Abstract

Polyacrylamide (PAM) has gained prominence as an effective Superabsorbent Polymer (SAP) for agricultural applications, particularly in arid and semi-arid regions. Its ability to enhance soil water retention and improve soil physical properties makes it a valuable tool for sustainable agriculture. This short communication explores the benefits and mechanisms of PAM-based hydrogels in increasing soil Water Holding Capacity (WHC) and Water Retention (WR), reducing irrigation water consumption, and improving soil quality. The article highlights advancements in the synthesis and application of PAM hydrogels, compares PAM with other polymers, and discusses innovations in its formulation. Overall, the incorporation of PAM in agriculture presents a promising solution to water management challenges, soil degradation, and crop yield improvement.
