How does SAP help in agriculture?

The researchers world over (specifically Iran, China, Europe and USA) have extensively worked on utilizing SAP for increasing water use efficiency and enhancing crop yield. Various studies have strongly recommended that soil conditioning with Super Absorbent Polymers could be an innovative facet in the field of agriculture, which works as miniature water storage reservoirs. Research evidences suggest that problems associated with traditional micro irrigation and the factors which are catalyst in practicing efficient irrigation techniques can be taken care of by conditioning the soil with SAP. Better water management can be attained with the application of polymers and considerable water saving can be done without compromising the crop yield. Present literature review has been conducted to have a quick access in understanding various properties of Super Absorbent Polymers (SAP, Hydro-gels, and Polymers) to be used in agriculture. Science of SAP, hydrophilic property, irrigation efficiency, effects under drought stress, effects over the morphological features of the plant, optimum use of fertilizers, biodegradability and application rates under different condition are thoroughly reviewed.
