The Effects of Superabsorbent Polymers on Soils and Plants

Current climate change is projected to have significant effects on temperature and precipitation profiles, increasing the incidence and severity of drought. Drought is the single largest abiotic stress factor leading to reduced crop yields. Given the large share of water use in the agriculture sector and very low efficiency in this sector, selection and development of the new strategies to improve and optimise irrigation water use with significant savings is essential. The usage of Superabsorbent polymers (SAPs) is one of the strategies in this regard. This paper briefly mentions to the previous studies about the effects of SAPs on soils and plants, suitable usage rate of SAPs for improvement of soils, raising of WUE and amount of irrigation water saving in this field. The results showed that SAPs could store water and nutrients and release them in drought stress conditions in light soils. Therefore, an acceptable biologic and grain yield with less irrigation water depth could be achieved.
