| Abstract: | Water-soluble polymer is a good soil conditioner which can be decomposed by micro-organisms. It has a good ad- sorption to soil nutrients so that the loss of element is reduced and the fertilizer efficiency is improved. A kind of slow release polymer fertilizer with nutrient elements is synthesized by adding degradable water-soluble polymer materials containing nitro- gen and phosphorus. The effects of reaction conditions on the fertilizer structure and efficiency are studied in laboratory. |
