Biodegradable agricultural super absorbents with high ability to absorb saline water under load

In this paper, an agricultural super absorbent based on acrylic acid, carboxy methyl cellulose and urea has been produced, which has the ability to absorb maximum saline water under load - the closest test to the actual soil conditions. In this paper, instead of using acrylamide, which is the term monomer in the field of agricultural super absorbent production, urea is a significant percentage of superabsorbent. Urea is an inexpensive domestic substance that has the ability to absorb relatively high water, so in addition to reducing the price of the final product, it is also used as agricultural fertilizer, which also helps the biodegradability of this product.This hydrogel was compared with commercial samples on the market and showed better results in tests of water retention and absorption under load than commercial samples.
