Abstract: In one aspect the invention provides matrix based fertilizer formulations that reduce plant nutrient leaching into water sources. In another aspect, the invention provides matrix based formulations that reduce pesticide leaching into water sources. In still another aspect the invention provides matrix based fertilizer formulations comprising both fertilizers and pesticides wherein the formulation reduces pesticide and plant nutrient leaching into water sources. The invention also provides methods for the application of matrix based fertilizer formulations.

Abstract: The biopolymer additive, in combination with water, functions as a soil conditioner that affects soil erosion and water infiltration. The biopolymer additive is derived from complex galactomannon-rich succulent plants. The succulent-derived (biopolymer) additive (SDA) may be used alone or in combination with polymers and copolymers of polyacrylamide (PAM). The combination of the SDA and PAM has a synergistic effect so that the resulting composition yields unexpected results and is a more effective treatment than either SDA or the PAM alone.
