Fertilizer additive containing GRE activity factor and preparation method therefor

Abstract

A fertilizer additive containing a GRE activity factor and a preparation method therefor, the fertilizer additive is composed of a modified derivative mixture, an enzyme composite system, sodium n-butyl phosphonoaminolevulinate, and an inert stabilizer. Through multi-component synergy, the fertilizer additive is configured to efficiently control the loss of nitrogen, phosphorus, and potassium nutrients, reduce their leaching, significantly increase the contents of nitrogen, phosphorus, and potassium elements in soil one month after fertilization compared with conventional fertilizers, achieve significant effects in controlling loss and preserving fertility, and improve fertilizer utilization efficiency.
