Granulær, langsomt avgivende gjödningsblanding og fremgangsmåte for fremstilling av gjödningsblandingen |
摘要 |
<p>A carrierless granular slow release fertilizer composition is prepared by spraying a urea-formaldehyde resin composition having a U/F molar ratio ranging from 2.4 to 13.3 onto finely divided solid particulate raw materials and cooling the resulting sprayed product to solidify the resin composition providing a matrix within which the solid particulate raw materials are bound. The fertilizer composition is characterized by having desired physical and chemical properties in regard to chain length of nitrogen polymers in the product, nitrogen release patterns, hardness and dust free nature of the product and the dispersibility characteristics of the product. The product has an abrasion index of about 0.800-1.000.</p> |
