Abstract
The disclosure relates to systems, compositions and methods for providing nutrients, root proliferants, crop protection agents and other crop inputs for a plant. The disclosure also relates to methods for increasing the uptake of a crop active compound into a growing plant.
Claims14
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.
