Review Article About Gel Polymers and Their Applications

One of the important applications of hydrogels is agricultural applications, as there is a controlled release of nutrients from the hydrogel into the soil, which are fertilizers loaded on the hydrogel. A large part of the fertilizer added to the soil is lost through leaching, especially in highly porous soils, in chemical processes, heavy rains, etc. A number of different polysaccharides, such as chitosan, pectin and carboxymethyl cellulose have been used to prepare hydrogels as a fertilizer release system for soil revitalization. Many studies have been conducted in this field. For example, Agaba et.al indicated that moisture retention in a particular soil due to the hydrogel is necessary to create a forest. Planted Water affects soil properties such as aeration, temperature, nutrient transfer, water absorption and conversion, which affects plant growth. Dimitri et al investigated the applicability of cellulose-based hydrogels in three different formulations, i.e. crosslinked by carbodiimide, as a carrier for sustained and controlled release of water and as nutrients in arid and desert regions.
