Scarcity and misuse of water reservoirs is a major global issue excruciating by the increase in population and pose serious and growing threats to sustainable development and protection of the environment. Saving water in irrigation is a vital solution in protecting water reservoirs.1 Superabsorbent polymers (SAPs) are lightly crosslinked hydrophilic hydrogels, which can absorb up to 2000 g/g water with reversible swelling properties.2 In the past decade, many researchers have been focused in the field of particulate composites of hydrogels. Meanwhile, many of those have focused on superabsorbent hydrogel composites, and superabsorbent hydrogel nanocomposites.3 Due to their unique properties, superabsorbent nanocomposites can find applications in different areas including agriculture, hygiene products, ion and dye removal, controlled release and sanitary products.2 - 4 These smart materials and smart delivery systems helped the agricultural industries to increase the efficiency of pesticides and herbicides, allowing lower doses to be used and protect environment.1 This report will review the key aspects of used superabsorbent polymers in agricultural area and highlighting the different classification and production background of superabsorbent polymers.
