These minerals can be applied directly to the soil as a granular fertilizer, sprayed onto the leaves foliar , or delivered to the soil through irrigation system fertigation. How much of each element and the best way to apply it will vary between orchards and growers due to differences in soil type, topography, and management practices.

A balanced nutrient program is a part of good horticultural practices. A nutrient program is never a replacement for proper pruning, crop load management, and pest control. Soil applied nutrients, either granular or fertigated, is the ideal means of supplying the bulk of a trees needs for such nutrients as nitrogen, phosphorus, potassium, and sometimes calcium.

Other micro-nutrients that should be checked and sometimes balanced every few years are boron and magnesium. Boron is highly soluble in the soil, which can result in large differences in boron levels under drip irrigation systems vs the alley ways in an orchard. Magnesium, while usually applied as a spray, will also be supplemented whenever Sul-po-mag or dolomite lime is added to acid soil.

There are some soil amendments that are used to help manipulate the chemical or structural make-up of the soil to improve conditions for nutrient uptake. Such soil amendments are various lime products, peat, compost, sulphur, gypsum, compost, and various mulch materials.

Foliar sprays are an efficient way to deliver some nutrients when they are required more at a specific growth period or when there are limitations to soil uptake by the tree.

However, foliar fertilizers are very limited in the total amount of minerals they can deliver to the tree and thus, are most effective for minerals required in lesser amounts micronutrients. In most orchards, foliar sprays of boron, zinc, and magnesium should be applied regularly to prevent the development of deficiencies of these elements.

Multiple calcium sprays are applied annually as a means to aid fruit quality. If needed, manganese, and iron must be applied as sprays. The best time of day for foliar sprays is the early morning when temperature favour slow evapotranspiration.

Morning is when the stomata pores in the leaves are open and the nutrients are taken up best when wet. With over-tree irrigation, apply mineral sprays as soon as possible following an irrigation to allow maximum time for absorption before the next irrigation.

The elapsed time between spray and the next irrigation must be not less than 24 hours but the longer the time the better. Fertigation is the addition of fertilizers with irrigation water. Information is growing with this technique as local experience is gained with research and grower interest.

Equipment specific to fertigation includes a back flow prevention device and equipment for injecting fertilizer into the system. A list of certified testers for backflow prevention devices is available at BC Ministry Agriculture offices.

Fertigation has several advantages:. Transport of nutrients directly to the root zone so that fertilizer amounts and timing can be precise.

Only soluble fertilizers can be applied and rates of fertilizers can be adjusted only by irrigation zone, not to suit individual trees. Begin fertilizer injections after the system operating pressure has stabilized following turn-on; and. Allow 30 minutes of flushing with water after injection has been completed prior to switching to the next zone or turning the system off.

Soluble fertilizers which have been successfully applied include urea, ammonium nitrate and calcium nitrate as sources of N. There is an advantage to using the more expensive calcium nitrate Ammonium polyphosphate , monoammonium phosphate , and phosphoric acid have been successfully applied as a soluble replacement for first year planting hole granular P applications.

Fertigation of phosphorus P is physically easier than the application of P to the planting hole. When using fertigation, lower amounts of P can be applied to achieve similar improvement in tree vigour and P nutrition. Although chelates or sulphates of most minor elements can be safely fertigated, such nutrients, if required, are more efficiently applied via foliar sprays.

Boron is important for pollen tube growth and thus, is needed at bloom to aid fruit set. It is also needed for movement of plant sugars, and new cell formation in shoots and roots. Fruit trees grown in the British Columbia interior often require ground and foliar applications of boron at some point.

However, excess boron is toxic to fruit trees, especially peaches, prunes and apricots. Leaf symptoms of boron deficiency and toxicity are similar in appearance. Therefore, where symptoms occur, leaf and soil testing must be done to determine which problem is present.

Periods of drought or water-logging of soils can artificially result in a boron deficiency in the tree due to poor root uptake from the soil. Soil and leaf analysis can be helpful in determining where boron should be applied and at what rate.

Leaves showing suspicious symptoms can be collected in May for analysis compared to regular leaf analysis done in July. Leaf analysis cannot be used to test boron levels after post-bloom sprays have been applied to foliage. To avoid this problem, boron can be applied effectively in the fall before leaves start to senesce.

In these cases and where boron toxicity is suspected, soil analysis is useful. High boron levels in the soil can be an indication of a potential soil drainage issue.

Issues could be a hard pan that is not allowing proper drainage or there is a problem of leaching or seepage from a higher property. Applying boron without testing could aggravate tree damage where boron levels are already high.

High boron levels in fruit are associated with early maturity and storage problems. Where required in the soil, boron ideally should be applied in August. Dry or spray applications to soil should be distributed evenly over the main root zone areas and should not be made within one month of liming.

Boron is normally applied to the soil at very small rates that can be difficult to apply uniformly and thus has started to be incorporated as a coating on fertilizer mixes to allow easier even distribution. Soil boron levels should be balanced with a soil application once every three years on fine and medium textured soils or annually on coarse soils.

The best boron application methods to the soil are through a blended fertilizer mix or as Solubor dissolved in water and applied with the herbicide sprayer. Care should be taken not to exceed recommended rates with use of multiple products that contain boron.

Foliar boron sprays can be combined with sprays of chelated zinc, magnesium, manganese and urea. Boron sprays may also be combined with some pesticides. This may include a supplemental boron spray of solubor Boron can be applied in the fall with other nutrients on all crops.

In apples and Anjou pears, boron can be applied with the tight cluster stage dormant oil spray or at the pink-bud stage if not used the previous fall.

Consult the container label to determine mineral-pesticide compatibility. Foliar boron sprays are not to be considered as substitutes for soil application in all years. Soil boron B values less than 0. Soil values should not exceed 1. It is relatively easy to increase leaf and fruit boron concentrations via fertigation of modest rates of 0.

The preferred time for fertigation applications though is within 4 weeks of bud break when leaf boron concentrations have been chronically low. Like nitrogen, boron is very soluble and can be leached from the soil with excessive irrigation, especially for sandy soils.

As boron has a narrow range of suitability for most fruit trees it is not advisable to exceed recommended application rates or else toxicity and growth reduction will occur. Calcium is very important for the building of strong cells in the fruit, new shoots, and roots.

Calcium deficiencies contribute to certain fruit disorders including bitter pit, internal breakdown, storage rots, cork spot Anjou pit , and alfalfa greening. Honeycrisp and large sized apples are particularly sensitive to bitter pit development.

Fruitlet samples are the best method to determine if there are adequate amounts of calcium reaching the fruit. Leaf samples are the next best choice for monitoring calcium levels in the tree. Soil samples are not useful for determining the amount of calcium needed by the tree; however the use of lime to correct pH can add calcium to the soil see Liming below.

Unfortunately, calcium is not highly mobile in the plant and can be limited in uptake from the soil in cool weather. The competition within the plant between leaves and fruit for limited calcium results in a need to supplement calcium through foliar sprays in season to the fruit every year.

Calcium sprays are most effective when applications start during the period of fruit cell division petal-fall when demand and interplant competition is high.

The next good timing is later in the season when the fruit is larger and acts as a bigger target. Calcium sprays alone cannot be expected to eliminate calcium related fruit disorders. There are several cultural factors that impact the amount of calcium in the fruit see cultural and chemical controls below.

Bitter pit on apples shows as small pits that resemble miniature bruises. The skin within the pit is grey, brown or black and the flesh beneath is dry, brown and spongy. Bitter pit is most common on vigorous trees bearing light crops and is especially common on large fruit in the upper part of the tree.

The symptoms may show in the orchard but more frequently they become apparent in storage. Bitter pit is a disorder that results from an inadequate supply of calcium to developing fruit. Cork spot, often called Anjou pit, affects only Anjou pears. Pears develop a bumpy, uneven surface as they approach maturity.

Affected areas turn yellow and soften prematurely. The flesh beneath the depressions is soft and turns brown or grey. Anjou pit occurs most seriously in seasons when hot, dry weather precedes picking. Cork spot is a disorder that results from inadequate supply of calcium to developing fruit.

Alfalfa greening Green stain affects only the Anjou variety of pears. Fruits develop dark green, slightly sunken areas on the skin shortly before picking. Alfalfa greening is a physiological disorder, most likely caused by a nutritional imbalance between calcium and nitrogen, and excessive irrigation.

Avoid dormant pruning practices that stimulate excessive growing points and growth in tree. Use bees to ensure good pollination for crop load and full seed set for drawing calcium to fruit.

Practice summer pruning in vigorous trees mid-July to expose fruit to calcium sprays. For Apples — There are several foliar calcium products to choose from. Some calcium products should not be tank mixed with other nutrients or pesticides, such as Calcium Chloride see warning below.

Apply choice product at 10 day intervals beginning at petal-fall. Calcium Chloride WARNINGS— Application of unbuffered calcium chloride almost always causes non-serious burn of leaf edges but severe leaf and fruit injury is possible under some conditions.

To reduce the chance of severe injury, be careful not to exceed recommended rates. Do not apply the spray under wet, humid, or slow drying conditions. Spraying when temperatures are high may also produce injury. Although the safe upper temperature limit is not known, it is suggested that damage may occur at about 27°C.

In hot weather, growers should apply the spray during the coolest part of the day. Compatibility of Calcium Chloride with Pesticides. Compatible with wettable powder formulations of Imidan. Do not mix with spray oils or emulsifiable concentrate formulations of pesticides.

Do not add spreaders, stickers or emulsifiers unless specific instructions for their use are given. Sprays should be applied promptly and not left in the spray tank longer than necessary. Not compatible with magnesium, zinc or other plant nutrient minerals. Not compatible with captan, carbaryl Sevin , thiophanate-methyl Senator.

For specific recommendations, consult your fieldman or Horticultural consultant. In general, the following table may be used as a guide.

Apply three or more sprays at 2-week intervals beginning mid-May. For dilute applications use 0. Early applications at the petal-fall or husk-fall stages are also beneficial for fruit quality in all stone fruit.

See chart for application rates of various products. Ca Sprays in Rain to Prevent Cherry Cracking. This application may not always work and is based on research using overhead irrigation application. Calcium sprays to prevent rain splitting go on during the rain event.

Can be applied every two hours during continuous rain showers. Potential problems — reduced fruit size if applied too often. The high concentration of salts can cause some leaf burning. Low leaf copper concentrations have been observed in a few Interior orchards, especially in young high density plantings.

Leaf copper concentrations in all crops less than 4 ppm, especially if accompanied by symptoms involving sudden withering of leaf tips and die-back of the terminal portion of apparently normally growing shoots in summer, may indicate copper deficiency.

Copper sulphate applied at g product per L of water using a gun sprayer should correct symptoms of copper deficiency. WARNING — Do not apply to fruit during the growing season, especially Anjou pears, as fruit russeting is likely to occur.

In other areas copper sprays have been applied at green tip or as a post-harvest foliar spray when there is no risk of spray injury. Post-harvest foliar sprays may also be applied as chelates or other copper containing compounds at recommended label rates.

Iron chlorosis can occur with high pH soils lime-induced chlorosis , such as seepage sites where salts have accumulated in the soils, or in water logged soils. Peaches and nectarines on peach seedling rootstocks are extremely susceptible to iron chlorosis. Foliage may be made greener by foliar application of iron chelate products.

This is a provisional measure and does not correct the basic cause, thus yearly application may need to be part of the orchard spray program if the underlying problem is a difficult to correct high soil pH condition. Although a temporary measure, it still can make an improvement in stem quality of cherries where iron deficiency is causing a problem.

When iron deficiency is severe, repeat once or twice at day intervals. It is best to apply early in the spring, under cooler temperature due to burning risk to plant tissue. Iron sprays may not be combined with sprays of pesticides or other minerals. Applied alone, they have occasionally injured sweet cherry and pear foliage and fruit.

Dilute application is not recommended. Suggested Range of Levels for Leaf Iron in all Fruit Crops. Magnesium is a critical component of photosynthesis.

Unless leaf magnesium is high, most orchards require at least one annual spray. Some orchards have become seriously deficient requiring 2 - 3 magnesium sprays annually. It can show up on McIntosh and Spartan basal leaves in a heavy crop year. High levels of potassium K or low levels of available phosphorus P in the soil can also result in poor uptake of magnesium in the tree.

Repeat preventative spray two or three times, at week intervals depending on the severity of the deficiency. Manganese deficiency occurs in only a few orchards, usually on alluvial fans near the lakes.

Frequently, deficiencies are associated with a high soil pH together with the accumulation of soluble salts in the soil. Other orchards may suffer from manganese toxicity.

Red Delicious and Fuji may show manganese toxicity in the form of bark measles. Apply manganese only if foliar analyses indicate that a deficiency exists.

Manganese sprays may be combined with sprays of boron, zinc chelate, magnesium or urea. Suggested Range of Levels for Manganese. Manganese - ppm. Nitrogen is the primary mineral used in tree fruit nutrition.

It is essential for tree growth, fruit sizing, and fruit set. However, too much nitrogen can lead to poor fruit colour and storage qualities, increased bitter pit, increased crown and root rot of apples, excess tree growth susceptibility to fire blight, increased pruning costs, mildew, increased populations of aphids, leafhoppers and pear psylla , and alfalfa greening and Anjou pit of pears.

When trees do not respond to increasing amounts of nitrogen, the cause is frequently a deficiency of some other nutrient, most often zinc. Nitrogen applications can be wasted with excessive irrigation sets that drive the nutrients down past the rooting zone.

Over irrigating and excessive nitrogen applications can be toxic in the environment due to leaching into ground or surface water. Nitrogen is best applied as a soil application very early in spring.

The nitrogen is then available very early to help the tree during critical growth and fruit development stages.

Nitrogen applications to the soil should not exceed end of May in all fruit bearing blocks. It is especially important in apples so that soil nitrogen levels are low by the time the fruit is colouring in late summer. In young nurseries and new plantings, soil applied nitrogen should not be applied after mid-July clay or mid-August sand depending on soil type.

Determining how much nitrogen to use is not always easy. The nitrogen needs of an orchard will be higher with young trees filling space, large crop years, and stone fruits. Any suggested rates in this chapter are just starting points and will need to be modified through observations and data from your own orchard blocks.

All nitrogen fertilizers must convert to the nitrate form of nitrogen in the soil for the majority of uptake by the tree. Some ammonium can be taken up directly by the tree. Thus, the different choices of fertilizers can vary in how long they take after application to be available to the tree.

The most commonly recommended ground nitrogen fertilizers used are urea and ammonium sulphate that can take up to 3 weeks to convert for tree uptake, especially in cool springs.

Ammonium sulphate is more acidifying than the other fertilizers. Ammonium nitrate is the old standard, but only available through limited controlled locations, requires ID, and is an expensive form of nitrogen. Ammonia urea sulphate Calcium nitrate Calcium ammonium nitrate CAN is half calcium nitrate quick uptake and half ammonium can take 3 weeks to convert with no acidifying effect.

Nitrate and urea forms of nitrogen are more easily leached out of the soil than ammonium forms however, ammonium will readily convert to nitrate under optimum pH and aerobic conditions. It may be spread evenly over the orchard floor in orchards with closer-spaced smaller trees, however, fertilizer rates should be adjusted to match the total area of application.

Spread fertilizer a day or two after a full irrigation set, then irrigate for only 2 hours following application to help move the fertilizer just into the root zone of the trees.

Urea fertilizer left sitting on the surface of the ground in warm weather can lose nitrogen to the air through volatilization. Rates and Frequencies of First-Year N Soil Broadcast Applications. First soil application recommended soon after planting. Most nitrogen fertilizers especially Nitrate forms are highly soluble and are washed from the root zone with frequent and over irrigation.

Fertigation Rates and Timings for First-Year Plantings. Commence applications at post-bloom when finished phosphorus applications. These fertilizer rates compensate for the inefficiency of nitrogen uptake from sandy soils where irrigation can leach nitrogen below the root zone.

Recent research has indicated in an orchard with a sandy loam soil and irrigation controlled by atmometer based scheduling that production and quality of apples could be sustained by application of a total of g nitrogen per tree, applied during any 4 week period.

If high density planted trees have failed to adequately fruit after first year, continue first year nutrition program. If vigour has been low, also investigate possibility of another nutrient deficiency leaf analysis or inadequate first year irrigation.

If vegetative vigour is excessive, reduce nitrogen application rates by to ½. Mature producing trees are considered to be those capable, due to size, of carrying 30 to 50 bins of fruit per acre. Reduce the suggested nutrient schedule if mature trees that are capable of carrying a full crop, have experienced a frost or event that results in a significantly lighter crop.

Smaller trees that must still grow to achieve a structure that fills the tree spacing and are older than 3 to 4 years may be carrying too heavy a crop for the tree size.

These weaker trees should receive the start of their nutrient schedule after bloom and should not have rates cut with the removal of crop load. In all apples, too much nitrogen can lead to poor fruit colour especially in heavy crop years , soft fruit, poor storage quality, increased bitter pit issues, crown and root rot of apples.

There can be varietal differences in nitrogen requirements. For example, Honeycrisp is especially sensitive to balance tree needs compared to fruit needs. The fruit requires low levels of nitrogen as long as growth is adequate pruning and crop load management seems to encourage adequate growth as fruit size and quality is easily negatively affected.

Factors such as fruit size, block colouring, crop load, susceptibility to bitter pit and maturity dates may influence the amount of nitrogen needed in a given block. Growers should plan to make adjustments to their nitrogen rates based upon these and other influencing factors.

Some of the rich silt soils may require very little, if any, nitrogen for mature producing trees for a number of years in a row. Vegetative growth, leaf nitrogen analysis, fruit size and fruit colour development must be used to adjust rates of application.

These nitrogen recommendations are guidelines only! There is no substitute for careful observation. As mentioned above, the rate will depend upon tree growth, commodity, and fruit quality.

The lower rates are for apples growing in good soil compared to the higher rates for peaches growing in sandy soil. As a good balance between cropping and vegetative growth is achieved, less nitrogen per kg of fruit is used.

Good consistently cropped trees have proportionately less vegetative extension growth. There is less demand for calcium, i. a better leaf to fruit ratio. High leaf to fruit ratios, that is lots of vegetative growth and a light crop, particularly under low humidity, creates a stronger leaf demand for calcium away from the fruit.

Large fruit size with a small crop will also contribute to a calcium dilution in the fruit. Too much or too little growth, as well as leaf analysis results provides the information needed to help adjust the required nitrogen rates for the following season.

Measure leading terminals growing outwards at an angle of 45 degrees around the outside of the tree and take an average of these measurements. Increase, reduce or eliminate the quantity of nitrogen fertilizer to achieve the correct amount of terminal growth as shown in the following table:.

Also known as Black Tupelo, this tree offers a dense buffet of small black berries that are irresistible to songbirds and game birds alike Fall and Winter is an often overlooked, but perfect time to get some seedlings in the ground.

Spring and summer applications of hydrated lime require care be taken to avoid deposits on foliage and fruit, which can suffer burning.

Lime must be broadcast evenly over areas in which the pH is low pH 6. These will usually be areas where fertilizer has been spread year after year.

Areas of an orchard in which soil tests show pH levels above 6. Shallow cultivation after application will aid in the absorption of lime. However, shallow cultivation can also damage tree roots, outweighing any advantage to cultivating in the lime. Limed soils begin to re-acidify from the surface upon reapplication of the commonly used nitrogen fertilizers urea, ammonium nitrate and ammonium sulphate.

Regular pH monitoring of the surface layer 10 cm will indicate when there is a need to reapply. Before planting trees, soil samples should be taken at cm depth.

If the soil pH is below 6. Lime should be applied at a rate to bring the soil pH to 6. Otherwise the pH could drop below 5. This chapter has been prepared in the spirit of encouraging effective use of high quality compost to improve the long term sustainability of fruit production in interior BC.

Not all compost is the same, and raw manure is not compost. Enhancing soil organic matter is critical for sustaining orchard productivity, particularly for orchards on coarse-textured soils with low organic matter contents.

Enhancing soil organic matter has multiple benefits that all contribute to improved root growth. For orchardists, the most effective means of enhancing soil organic matter is through the addition of compost to the root zone, either through incorporation into trenches or planting holes before replanting, or through surface application to established plantings.

Composts are distinct from manures and other organic wastes: It is very difficult to use manures and some other non-composted organic wastes as soil amendments without injuring crops and having negative impacts on environmental quality.

Such materials can burn roots salt stress, ammonia, organic acids , and surface application can increase the prevalence of fecal bacterial contaminants in the orchard environment which in-turn increases the probability of fruit contamination. How is compost distinct? Compost is stabilized earthy matter having the properties and structure of humus or native soil organic matter that is beneficial to plant growth when used as a soil amendment.

Compost is produced by actively managing the decomposition of large quantities of fresh organic matter. The first phase of composting involves intense microbial activity as the most easily decomposed parts of the organic matter sugars, starches, proteins are quickly metabolized.

In most cases, this phase generates heat and the material reaches temperatures in excess of 50 C, which kills fecal bacteria, plant pathogens, insects and most weed seeds.

This property of stability is important because the application of non-composted organic materials to soil in relatively large quantities can stimulate undesirable flushes in soil microbial activity resulting in the immobilization of nutrients and production of organic acids that are detrimental to root health.

In the case of organic wastes with high nitrogen contents, such as poultry manure, high application rates can also generate toxic levels of ammonia in the soil. Compost can be produced from a wide variety of initial feedstocks, including manures, prunings, municipal yard trimming, kitchen wastes from municipal greenbin collection programs, food processing wastes, old or spoiled hay, and wood wastes.

Growers can obtain finished compost from commercial and municipal composting operations. Composts can also be made on-farm. The requirements of OMRR ensure that the material has passed through a thermal phase adequate to kill-off fecal bacteria, and that the finished compost is stable, i.

The requirements of OMRR also include limits for heavy metals that are set to prevent their accumulation to problematic levels with long-term repeated compost application. Collectively, the requirements of OMRR ensure that the compost is generally safe for the environment and stable. Some municipal composts include biosolids or municipal sewage sludge as a feedstock.

Such composts can be very high quality and meet OMRR specifications for environmental safety. It should be noted, however, that guidelines for organic production and some food safety certification programs such as CanadaGAP prohibit the use of compost made with biosolids as a feedstock.

On-farm production of compost: For growers in the Okanagan and Similkameen, poultry manure from the Fraser Valley is a common source of feedstock for making compost.

Using inadequately or improperly composted poultry manure is not substantially different from using fresh poultry manure. As described above, such materials can burn roots salt stress, ammonia, organic acids , and surface application can increase the prevalence of fecal bacterial contaminants in the orchard environment.

Growers attempting to produce on-farm compost from poultry manure should be familiar with how to compost properly. A list of suppliers of composts and manures for composting:. Bighorn Contracting Ltd. Phone GlenGrow, City of Kelowna.

Wholesale quantities of GlenGrow are available at the Glenmore landfill, North Glenmore Road. Phone compost info line Ogogrow contains biosolids , City of Kelowna. Wholesale quantities of Ogogrow are available at the Regional Compost Facility, Commonage Road.

Superior Peat Inc. includes bark mulches and composts , Carmi Avenue, Penticton Phone Corfe Farm. Wholesale quantities of poultry manure compost, delivery available. Southern Plus Feed Lot.

It is important to note that chemical properties can vary substantially between composts made with the same feedstocks, and even among batches of compost made at the same place out of the same feedstocks.

Regardless of whether composts are obtained from commercial suppliers or made on-farm, they should be analyzed before use. The influences that composts have on soil and tree growth are affected by how they are applied as well as their properties. See Soil and Tissue Testing Labs page 9. Typically, very little of this N is immediately available to the crop as occurs with chemical fertilizers, but becomes available in the long term as the organic material decomposes and interacts with soil N.

Consequently, composts should be considered as soil amendments rather than N fertilizers. Nonetheless, they will affect soil N availability.

This can occur for composted dairy solids. Total P and K contents: As with N, the P and K in compost is not as readily available as it is in fertilizers. In contrast to N, however, less is known about factors governing the availability of P and K in composts.

Electroconductivity EC : The EC of compost is a critical property reflecting the salinity of applied materials. It is possible to utilize high EC amendments, but care must be taken to avoid direct contact with roots or the material must be sufficiently diluted with low EC soil to prevent root burn.

In general, surface application is safer than mixing compost into root zone soil when EC is a concern. Composts are generally mixed into soil in planting holes or trenches before replanting or surface-applied as a mulch.

The following are general guidelines for commonly used rates. Maintenance rate - 4 tons per acre covered 4 tonnes per hectare or approximately 10 yards.

In response to trees showing decline — 12 tons per acre covered 12 tonnes per hectare. Root examination before and after application is recommended and may indicate when additional applications are necessary.

Compost is generally spread by shovel off a trailer. In this case the compost should be spread evenly in the herbicide strip. The application rate can be estimated by weighing a 20 litre bucket, spreading the contents evenly in a 10 sq.

This gives a visual indication of the rate. For example, a 20 litre bucket full of compost zinc sulphate container should cover the 4 ft.

herbicide strip of 2 ½ trees on a 1 ft. Biochar: Biochar is an amendment which has received recent publicity due to its perceived environmental benefits which include the potential to stabilize and elevate the carbon content of soil at the same time providing the benefits associated with increasing organic matter content.

It is produced by the incomplete combustion of organic material such as forestry waste wood under low oxygen conditions and is often a by-product of its use for energy production.

There are several BC companies actively researching its production. At present there is considerable variability in its composition and limited research on its benefits for use in perennial horticultural production systems.

Humic materials: Commercial formulations of humic acid or humate solid form of humic acid are being marketed as growth-promoting soil amendments. These materials are extracted from ancient decomposed plant material in the form of leonardite or lignite soft forms of coal. Their nutrient contents can be low but formulations can be supplemented by the addition of nutrients.

They also have high cation-exchange capacities. The effects of these materials on fruit tree growth have not been studied adequately to support any recommendations. A phosphorus amended humic material improved initial growth of grape in half the plantings when tested in local vineyards.

Liquid organics: There are several liquid organics available and suitable for application with irrigation water, but there have been few comparisons of their effectiveness. Compost teas are from the leachate produced by aerated or anaerobic no oxygen digestion of manures and have been advocated for insect and disease control and as nutrient supplements.

There is limited documentation of their effectiveness under field conditions. Vermicomposts: Composting carried out via earthworms does not include a high temperature incubation period since temperatures above 35 C kill earthworms.

Commercially available vermicomposts will have had to meet requirements of OMRR with respect to pathogen reduction. Acceptance of vermicomposts can be greater than that of composts because of better visual aspect, high nutrient content and microbiologic activity but there is limited documented proof of superior performance relative to other composts from replicated field trials.

Over the past 20 years a wide range of field experiments have been conducted in grower and government research station orchards to test the effectiveness of increased application of organic matter applied either as surface mulches or amendments incorporated into the soil profile.

The experiments have been conducted in high-density apple orchards on dwarfing rootstocks and involved randomized and replicated comparisons of treatments carried out for years. The number of sites where increased use of organic matter improved orchard performance primarily increased tree yield is summarized in Table 1.

It is important to note that about half of the trials with incorporated amendments were with compost. In one orchard it was found that surface mulching and amendment incorporation buffered against water stress and associated reductions in fruit size which occurred from accidental failure in the irrigation system.

Summary of number of orchards exhibiting improved performance in multi-year experiments conducted over the past 20 years by PARC-Summerland in grower and research high density apple orchards on dwarfing rootstocks. From this data it can be concluded that use of surface mulches has generally been more effective than incorporation of amendments and that benefits have not always been observed.

In the course of experimentation it was discovered that organic amendments may not result in improved growth of trees on sites with fertile soils or with strong fertigation programs suggesting that for these sites there was no measurable effect on tree performance by the addition of compost.

However, as previously noted, compost can be used to promote long term improvements in soil quality and nutrient reserves. Although use of composts can improve soil moisture regimes this is not a substitute for proper and timely irrigation. For example high frequency irrigation four times daily with small volumes of water could be more effective than surface mulching on a very coarse loamy sand soil.

Also over-irrigation resulting in excessive leaching of nitrogen mineralized from compost could negate the benefits of using composts. Compost is not a substitute for fertilizer programs. Routine soil and leaf analysis are still recommended in order to maintain nutrient balance in tree fruit blocks.

Growers are encouraged to discuss their plans for composting with their field person or with the BC Ministry Extension Service. Organic application could be ineffective when an important limitation such as replant disease or a nutrient deficiency such as potassium was unaffected by the treatment.

Although beneficial, the grower should not rely on composts to overcome severe replant disease or nutrient deficiency which can often be diagnosed by soil analyses or a plant pot test at the time of planting.

As previously indicated compost with a high salt content can inhibit plant growth particularly if concentrated around bare roots. BC Tree Fruit Production Guide.

Currently Viewing: Fruit Tree Nutrition. Fruit Tree Nutrition Monitoring and Assessing the Nutrient Needs of the Orchard Proper balanced nutrition is important in all crops; however, knowing what the right nutrient needed at the right time for the right reasons with the right product can be very different between commodities, orchards, and seasons.

Leaf Analysis Leaf analysis is currently the best available method of determining nutrient status of most minerals in fruit trees. Leaf Sampling Methods for Orchards What to sample : A sample is a composite sample of leaves from multiple trees within a similarly comparable block within the orchard and should not represent more than 10 acres.

Fruitlet Mineral Analysis Like soil and leaf analysis, fruitlet analysis can be a valuable tool when making decisions about feeding programs in apple orchards. Optimum 'Ambrosia' fruitlet mineral values and ratios for samples collected six weeks before anticipated harvest.

Soil Analysis Soil analysis is mostly used to determine the soil acidity or alkalinity pH , the level of soil salts as electrical conductivity EC , and boron. Soil Sampling Methods for Orchards When to sample: Soil sampling is typically done in the fall or spring.

com MB Laboratores Ltd. com Pacific Soil Analysis Inc. net Apple Leaf Drop Apple leaf drop is sometimes diagnosed as a disease or sometimes as a nutrient deficiency. Application Methods of Mineral Elements All fruit trees in the British Columbia Interior require applications of mineral elements in addition to nitrogen.

Fertigation has several advantages: Transport of nutrients directly to the root zone so that fertilizer amounts and timing can be precise. Reductions in the amount of fertilizer applied relative to standard broadcast application.

Less excess nutrients will therefore be available to be leached and pollute the groundwater. Fertigation cautions: Drip irrigation system must be well designed to provide uniform water distribution System must be maintained regularly to prevent plugged emitters.

To ensure that fertilizer is uniformly distributed regardless of the irrigation system layout: Begin fertilizer injections after the system operating pressure has stabilized following turn-on; and Allow 30 minutes of flushing with water after injection has been completed prior to switching to the next zone or turning the system off.

Such procedures are especially important if injections are infrequently made i. Mineral Nutrients Boron B Boron is important for pollen tube growth and thus, is needed at bloom to aid fruit set. Apply only when soil or leaf levels of boron are low.
