| Abstract Scope |
Hydrogels derived from plant-based polymers such as starch, cellulose, guar gum, and pectin are gaining prominence in smart agriculture due to their water-retention capacity, biodegradability, and environmental safety. This mini-review explores recent developments in the formulation and performance of natural hydrogels designed for controlled water and nutrient release. Emphasis is placed on their swelling behavior, structural modifications, and field performance under drought-prone conditions. Applications in seed coating, soil conditioning, and precision farming are also discussed. Plant-derived hydrogels present a promising route for eco-friendly agricultural intensification while minimizing environmental impact and improving soil resilience. |
