Controlled release vegetation enhancement agents coated with sulfonated polymers, method of production and prcesses of use

A method of producing controlled release fertilizers comprising:

• (a) providing a vegetation enhancement agent consisting of a first member selected from the group consisting of at least one nitrogen fertilizer including a member selected from the group consisting of an inhibitor of urease and an inhibitor of nitrification activity, and a slow release fertilizer, and mixtures of a pesticide and a member selected from the group consisting of at least one macronutrient, micronutrient, nitrogen fertilizer including a member selected from the group consisting of an inhibitor of urease and an inhibitor of nitrification activity, and slow release fertilizer;
• and
• (b) coating at least one surface of said vegetation enhancement agent with a sulfonated polymer dissolved in a solvent system including an organic liquid to form a controlled release coating on said vegetation enhancement agent wherein said first controlled release film comprises an interpolymeric complex of a neutralized sulfonated polymer and an amine containing polymer, said amine containing polymer containing basic nitrogen atoms wherein said basic nitrogen content ranges from about 4 to about 500 meq. per 100 grams of said amine containing polymer.

An agricultural process comprising:

• providing at least one layer of barrier material comprising a first film controlled release of sulfonated polymer between a vegetation enhancement agent and wherein said first controlled release film comprises an interpolymeric complex of a neutralized sulfonated polymer and an amine containing polymer, said amine containing polymer containing basic nitrogen atoms wherein said basic nitrogen content ranges from about 4 to about 500 meq. per 1 00 grams of said amine containing polymer, said vegetation enhancement agent consisting of a first member selected from the group consisting of at least one nitrogen fertilizer including a member selected from the group consisting of an inhibitor of urease and an inhibitor of nitrification activity, and a slow release fertilizer, and mixtures of a pesticide and a member selected from the group consisting of at least one macronutrient, micronutrient, nitrogen fertilizer including a member selected from the group consisting of an inhibitor of urease and an inhibitor of nitrification activity, and a slow release fertilizer, and vegetable matter to control exposure of said vegetable matter to said vegetation enhancement agent.
