摘要:
Superabsorbent polymer (SAP) products for use in agricultural applications, and methods of making and using the same are disclosed. Certain of the SAPs include a monomer or a mixture of monomers, selected from acrylic acid, acrylamide, acrylonitrile, methacrylamide, 2-acryloamido-2-methyl-propanesulfonic acid, methacrylic acid, vinyl sulfonic acid, ethyl acrylate, potassium acrylate, derivatives thereof or mixtures thereof, that is graft polymerized onto a starch in the presence of an initiator to form a starch graft copolymer.
摘要:
Methods of making and using starch graft copolymers produce particle sizes useful in granule applicators for applying to agricultural fields. Starch graft copolymers on field crops provide excellent anti-crusting properties, increased seed germination and stand, increased crop growth, increased crop yields and reduced water requirements.
摘要:
Superabsorbent polymer (SAP) products for use in agricultural applications, and methods of making and using the same are disclosed. Certain of the SAPs include a monomer or a mixture of monomers, other than acrylonitrile, that is graft polymerized onto a starch in the presence of an initiator to form a starch graft copolymer that is cross-linked and the SAP product is isolated.
摘要:
A method of and a product formed by entrapping a bioactive, growth-promoting additive in a starch matrix to form a starch-based, superabsorbent polymer product for use in agricultural applications involves (1) graft polymerizing a monomer and a starch to form a starch graft copolymer including a starch matrix; (2) isolating the starch graft copolymer; (3) forming particles of starch graft copolymer; and (4) adding a bioactive, growth-promoting additive such that at least some of the bioactive, growth-promoting additive is entrapped by the starch matrix. Following placement of the starch-based SAP including a bioactive, growth-promoting additive in proximity to a plant, root, seed, or seedling, growth of the plant, root, seed, or seedling is promoted because availability of beneficial nutrients is increased.

Methods of making and using a superabsorbent starch graft copolymer involve producing starch graft copolymers having particle sizes useful in granule applicators for application to agricultural fields. Starch graft copolymers applied to field crops provide excellent anti-crusting properties, increased seed germination and stand, increased crop growth, increased yields, and reduced water requirements.

摘要:
A superabsorbent polymer combined with a beneficial additive and method for administering the same in agricultural applications is disclosed. A method for delivering a beneficial additive in agricultural applications includes obtaining a beneficial additive combined with a superabsorbent starch graft copolymer and dispensing the combined beneficial additive and superabsorbent polymer in an agricultural environment.
