Agricultural hydrogels are granules that hold the water and swell many times their original size when exposed to water. When there is a lot of rain or irrigation, it can absorb a lot of moisture and store it, then release it when there is a drought when the rhizosphere zone dries up to lessen crop water requirements. By forming connections with water molecules, the cross-linked superabsorbent polymer may absorb aqueous solutions. This innovative method of water management in water-stressed conditions lower losses through evaporation, deep percolation, runoff, and preserving crops’ active rooting zones’ soil moisture. The availability of soil water, which also has a significant impact on agricultural activity in regions with limited water resources, is crucial for the survival of both plants and the microbial community in the environment. It is used in agriculture for some things, such as retention of water in the soil pesticides and nutritional distribution, the grain’s layer, reducing eroding soil, and as a nutrition ingredient. The comprises an amazing capacity to improve a variety of soil’s physicochemical, hydro-physical, and biological properties while also lowering irrigation requirements, and enhancing nutrient and water use efficiency. It will be a benefit to include the hydrogel polymer workable and useful innovation instrument to boost agricultural yield under moisture-stressed conditions. Owing to the scant moisture and erratic temporal and geographic separation that severally threatens the viability of agriculture in the world’s arid and semiarid regions, water shortage is a major environmental issue. The current approach to deficit watering innovation includes regarded as a crucial element in conditions of restricted water availability to preserve favorable higher water use efficiency with a balance of soil moisture in the root zone that doesn’t affect crop production. By prohibiting the polymers from maintaining their capacity to release moisture and swell under moisture deficiency situations, enhancing plant growth and crop productivity in arid and semi-arid areas all around the world. They also prevent deep water evaporation loss extravasation, as well as dumping of vital nutrients. The development of hydrogels as controlled-release devices have seen a lot of scientific interest recently. The current study gives a brief overview of the numerous synthesis techniques, hydrogel types, and cross-linking agents that have been employed to create hydrogels with properties that are suited for agricultural applications
