This document describes a water retainer product called PolySorbTM. It is a superabsorbent polymer made of cross-linked acrylamide and potassium acrylate. When water contacts PolySorbTM, it is drawn into its molecular network through osmosis. As soil dries, PolySorbTM releases up to 95% of absorbed water. The document provides application instructions and advantages, such as increasing water and nutrient retention in soil while reducing irrigation needs by 30-50%. PolySorbTM demonstrates no toxicity and degrades naturally into beneficial compounds.
