Superabsorbent polymers agricultural applications

Superabsorbents are superabsorbent polymers, which are loosely crosslinked hydrophilic polymers and have ionic charges in the polymers. They absorb water, swell, and retain aqueous solution above hundred times their own weight. Because of the excellent characteristics, the superabsorbents have been widely used in many applications such as disposable diapers, feminine napkins, soil additives in agricultural or horticultural applications, gel actuators, water-blocking tapes, materials for drug delivery system, absorbent pads, etc., where water absorbency or water retention is important. 

Starch from surplus corn has been converted into a superabsorbent material known as SUPER SLURPER. This is being marketed under license by several companies for use in removing water from refined petroleum products and as an absorbent in bandages and diapers. Biodegradable plastic films of starch mixed with other polymers find application as mulches in agriculture and as a...

Application of superabsorbent polymer (SAP) in agriculture and greening ean be largely divided into the following two methods. The first method is to mix dried SAP into soil. Upon watering, SAP absorbs and holds water, showing the effeet of inereased water-holding capacity. Practical applications include ... 

Superabsorbents can also help conserve water in a variety of agricultural and horticultural applications. Mainly, the polymers are used in the same way as...
