14 Claims

1. A method of increasing yield of a crop in a field, the method comprising providing an agricultural composition during planting of the crop seed in the field, wherein the agricultural composition comprises

a. a root proliferant component, wherein the root proliferant releases about 70-90 cumulative % of phosphate between about 30-90 days into soil after planting the crop seed and comprises about 0.002 to about 2.0 grams of phosphate; and

b. a crop protection agent, wherein the crop protection agent is released into soil such that about 70-90 cumulative % of the crop protection agent is available to the crop during about 20-100 days after planting the crop seed and the uptake of the crop protection agent by the crop is increased due to the presence of the root proliferant;

wherein the agricultural composition comprises a biodegradable polymer layer having a water permeability of about 1 to about 2000 g/m²/day at 25 degrees Celsius and thereby increasing the yield of the crop.
