The hydrophilic polymer in three levels was blended with sandy soil. The aim of this study was an evaluation of the evaporation rate, water retention capability, and saturated water content of polymer-treated soils, for determination of plant survival and seed germination rate by cylinder and steep surface experiments. According to the results, sandy soil treated by a superabsorbent polymer (SAP) showed a significant rise of the soil water holding compared with the controls. In addition, in polymer-treated soils, there were significantly more sprouting seeds than in the controls. The survival times of ligneous and grass plants were lengthened under water scarcity. The treatment with 0.4\% polymer was the optimal choice for sandy soil amendment on a steep surface.}, issn = {0022-4561}, URL = {https://www.jswconline.org/content/73/2/173}, eprint = {https://www.jswconline.org/content/73/2/173.full.pdf}, journal = {Journal of Soil and Water Conservation} }
