Abstract
The present disclosure relates to zeolite based agricultural compositions and their use as delayed release compositions. The delayed release compositions comprise an agricultural composition absorbed into or on the zeolite and the impregnated zeolites can then be coated with a polymer material to give the delayed release composition. Release of the agricultural composition can be tuned to coincide with the demand needs of a growing plant.
Claims17
A delayed release composition comprising:
- a) a core comprising a zeolite impregnated by an agricultural composition;
- and
- b) a layer of a polymer composition on at least a portion of the core,
- wherein the agricultural composition comprises a fertilizer, a pesticide, a plant growth regulator, a Nod factor or a combination thereof, and wherein the polymer composition comprises a polymer and, wherein the polymer is a polylactic acid polymer, polylactic acid glycolic acid copolymer, polybutylene succinate adipate copolymer, a polybutylene succinate copolymer or a blend thereof.

A delayed release composition comprising:
- a1) a continuous matrix of a polymer composition;
- and
- b1) dispersed within the polymer matrix, a zeolite impregnated with an agricultural composition,
- wherein the agricultural composition comprises a fertilizer, macronutrients, micronutrients, a pesticide, a plant growth regulator, a Nod factor or a combination thereof, and wherein the polymer composition comprises a polymer and, wherein the polymer is a polylactic acid polymer, polylactic acid glycolic acid copolymer, polybutylene succinate adipate copolymer, a polybutylene succinate copolymer or a blend thereof.
