Biodegradable and environmentally friendly agricultural hydrogels based on urea

In this project, based on acrylic acid, carboxy methyl cellulose and urea, agricultural hydrogel has been produced that has the ability to absorb maximum water under load due to soil weight and water salinity due to dissolution of salts in water. In this project, instead of using acrylamide, which is the common monomer in the field of agricultural hydrogel production, a significant percentage of urea is used in hydrogel. Urea as a cheap material with relatively high water absorption, in addition to reducing the price of the final product, as a nitrogen-rich material, has converted this hydrogel into a slow release fertilizer.
