Applications of Biopolymeric Gels in Agricultural Sector

Abstract

Hydrogels are three-dimensional cross-linked polymeric network having substantial affinity for water. Classes of hydrogels which are derived from biopolymers have been widely used in number of industries because of their biocompatibility and environmental safety. In agricultural sector, they are extensively used as soil conditioners, water retainers, and bio-remediating agents. Their recent application claims customized diffusion of different materials such as fertilizers and pesticides into surrounding soil matrix. They are proving very useful for crops in efficient distribution of water with minimum wastage, and utilization of fertilizer nutrients and pesticides in targeted zones. This chapter covers the recent advances on biopolymeric gels and different aspects of their usage with respect to agricultural sector.
