Innovative fully soluble NPK gel fertilizers based on biopolymers with controlled release of nutrients

Abstract

The purpose of this work was to obtain and evaluate the properties of two innovative fertilizers based on multicomponent polymers, characterized by the controlled release of nutrients. One of the methods is based on the use of multicomponent liquid fertilizers containing different amounts of microelements NPK 15-10-50 with polyacrylamide hydrogel. The second method involves cross-linking biodegradable polyvinyl alcohol with multi-component NPK fertilizers.
