water sources optimizing required a suitable irrigation program. different material can use to increase water use efficiency. superabsorbent is one of the materials where used in around the world. these materials put in the soil and absorb water so that reserved water is usable by plant in the time of drought stress and they can reduce stress and lead to prevent yield loss. therefore, the exper...
The present study describes two different methods for the preparation of superabsorbent polyacrylamide (PAAm) hydrogels for application in farming of sandy soil. The two methods were employed to induce the crosslinking of the polymer matrix. In the first method a PAAm paste was exposed to gamma rays, while in the second method the polymer was thermally treated in the solid phase. Crosslinked PA...
