ABSTRACT:
A vegetation enhancement composite including a vegetation enhancement agent consisting of a first member selected from the group consisting of at least one macronutrient, micronutrient, nitrogen fertilizer including an inhibitor of nitrification activity, slow release fertilizer, and mixtures of such members and a pesticide; and at least one first controlled release film including a sulfonated polymer coating at least a portion of a surface of the vegetation enhancement agent. A method of producing controlled release fertilizers involving providing a vegetation enhancement agent consisting of a first member selected from the group consisting of at least one macronutrient, micronutrient, nitrogen fertilizer including an inhibitor of urease, nitrogen fertilizer including an inhibitor of nitrification activity, slow release fertilizer, and mixtures of such members and a pesticide; and coating at least one surface of the vegetation enhancement agent with a sulfonated polymer dissolved in a solvent system including an organic liquid to form a controlled release coating on the vegetation enhancement agent. An agricultural process involving the application of a vegetable enhancement agent coated with a sulfonated polymer to plant growth medium to stimulate germination and enhance growth of vegetable matter.
