Fertilizer formulation for reduction of nutrient and pesticide leaching

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.
