Apples

Apples respond well to foliar and soil applications of AGGRAND fertilizers. Peak foliar responses are obtained on perennial crops, including apples, by applying AGGRAND fertilizers after the leaves open during pre-bloom, during post-bloom and during fruit set. While nitrogen is an important nutrient in apple production, apple trees store nitrogen from season to season and too much nitrogen affects fruit quality and shelf-life. On the other hand, nitrogen deficiency may limit production. One symptom of nitrogen deficiency is when a tree’s leaves are chlorotic after they open in spring. Find the right balance of nitrogen in apple trees by adjusting the foliar spray and soil application rates, type of fertilizer applied and the number of applications.

Foliar Applications:

Per-acre mix ratio:

1 gallon AGGRAND Natural Fertilizer to 50 gallons of water (depending on tree density, spray equipment and canopy volume). Apply after the leaves open. Repeat after bloom if the trees require more nitrogen.

2 quarts AGGRAND Natural Kelp and Sulfate of Potash to 50 gallons of water and apply after fruit set. Repeat 3-4 weeks before final harvest.

Rates vary according to soil fertility and other inputs used. Lower dilution rates are more effective than higher dilution rates. Two or three applications may be more effective than one heavy application. If other constraints only allow one trip over the field, do not exceed a 3% dilution rate (3 gallons AGGRAND fertilizers to 97 gallons water).

To reduce susceptibility to attack of insects and disease-causing organisms, apply a per-acre mixture of 1 quart AGGRAND Natural Kelp and Sulfate of Potash and 50 gallons of water when signs of infestation become apparent.

Soil Applications:

Per-acre mix ratio:

3 gallons AGGRAND Natural Fertilizer to 30 gallons of water. Apply in spring and fall if soil is hard and low in organic matter. If bitter pit is a problem, add 1 gallon of AGGRAND Natural Liquid Lime to the spray tank to supply additional calcium.
