Using AGGRAND: Crop Application Rates

Coffee

Nitrogen is typically the limiting macronutrient in coffee production. ¼ to ½ pound of actual nitrogen per tree per year is recommended when using chemical fertilizers. However, when growing coffee organically only a fraction (5-10%) of that amount needs to be applied because biological activity in the soil fixes nitrogen from the atmosphere and releases nitrogen from organic matter that is applied as compost, cover crops, and AGGRAND fish and kelp products.

Minor nutrient deficiencies are normally the only other disorders necessitating the application of corrective measures. In the majority of cases the application of AGGRAND fertilizers corrects any deficiencies.

Applications of AGGRAND Natural Organic Fertilizers stimulate soil biological activity, supply macro and micronutrients, and release nutrients from the soil. When AGGRAND Natural Organic products are applied along with organic matter plant cell structure and soil water holding capacity are improved.

Foliar applications:
The foliar application of AGGRAND fish and kelp fertilizers corrects many micronutrient deficiencies and increases drought, heat, and cold tolerance of coffee. Foliar application of AGGRAND Natural Organic Fertilizer reduces pest problems in coffee production. The foliar application of AGGRAND Natural Organic products as a part of the early bloom, summer and fall spray programs is effective in reducing the number of insect pests.

1.) Mix 3-5 gallons AGGRAND Natural Organic Liquid Fertilizer 4-3-3 with 25-40 gallons of water per acre. Apply as a fine mist with enough solution to thoroughly cover leaves. Apply with pre-bloom, post-bloom, and fruit set.

The addition of fulvic acid increases penetration of the leaf cuticle. Add 1-3 quarts to the spray tank along with the fertilizer. Use 1.3 quarts when applying AGGRAND Natural Organic Liquid Fertilizer 4-3-3.

Rates vary according to soil fertility and other inputs used. Higher dilution rates are more effective than lower dilution rates. Do not exceed a 3 to 4 % dilution rate.

The addition of a biodegradable surfactant increases uptake by increasing adhesion to the leaf surface. Apply AGGRAND Natural Organic products in early morning or late evening. Do not apply before or after rainfall or irrigation. On standard sprayers use the turbo flood jet nozzles when applying AGGRAND Natural Organic products to reduce clogging.

Soil/Root applications:
Apply 3-5 gallons of AGGRAND Natural Organic Liquid Fertilizer 4-3-3 diluted in 20-81 gallons of water. Apply to 1 acre with root application to each tree, once per month.

General applications:
Apply 1-3 pints per tree per year (rates depend on tree population, soil fertility, and the use of cover crops and/or application of compost or manure). The total amount includes soil and foliar applications.
The application of compost, composted manure, and incorporation of green manure crops improves soil structure, nutrient, and water holding capacity of desert soils. Annual medics (medicago spp) such as barrel medic (medicago truncatula), strand medic (m. littoralis) and snail medic (m. scutellata) are low growing and adapted to neutral to alkaline soils. These species will grow during the cool season and go to seed before summer. They add organic matter and nitrogen to the soil. They must be kept short by mowing to 3-5 inches in height.
