Abstract : Three dimensional cross-linked macromolecular structures of polymeric hydrogels (PHGs) that have more capability of absorbing and holding large amounts of water in comparison of their dry mass. Their outstanding water retaining potential and ability to controlled discharge of nutrients, agrochemicals, and bioactive compounds have attracted considerable interest in sustainable agriculture. This review illustrated about the structure, classification, synthesis, and applications in agricultural field. Their hydrophilic nature of polymeric materials has emphasis on their responsibility in soil conditioning, water management, fertilizer delivery, crop productivity, and microbial activity. The advantages, limitations, and future prospects of synthetic, natural, and hybrid hydrogels in agricultural systems are also discussed.

Keywords : Hydrogels, Agrochemicals, Soil Conditioning, Sustainable Agriculture, Natural and Hybrid Hydrogels.
