چکیده:
Production of agriculture products is significantly depended on water and fertilizers. Nitrogen which is existed in fertilizers is one the most important nutrient for plants growing. However, nitrogen washes in form of nitrate in farms leads to pollution of underground water. Slow or controlled release of fertilizer technology can be appropriate solution of this problem and can decrease environmental pollution considerably. In this method by leaching of active substances underground water pollution is prevented. In addition nutrient is delivered to plant root gradually. In this research by synthesis of zeolite Nano-Composite with acrylate structure release behavior of potassium nitrate as a fertilizer have been studied. Since using nano-particle can leads to increase water adsorption and improve release behavior in system, Y-type Nano-Zeolite is used as the dispersed component. Various amounts of acrylate monomers have been studied. Finally, advantages of this technology and prevention of surface/underground water pollution are investigated.
