Abstract:
     In the mixed fertilizer containing potassium provided by this invention, the gas dust of iron-smelting blast furnace, which is rich in potassium and more kinds of trace elements needed by the growth of crops, is used as its raw material and the pulp made of planes is used as adhesive. Above two matters are mixed with nitrogenous and phosphate fertilizers, going through mechanical prilling, to make up a particulate mixed fertilizer containing more than two kinds of main nutrient elements and more kinds of truce elements. This mixed fertilizer contains potassium of 5-25% as well as such elements as Ca, S, Zn, MgO, Cu, Mo and Mn. Its productive technology is simple. Its raw materials are easily available. Its contents of nutrient elements can be adapted to the requirements of different soils and crops, so having better effect of increasing production of crops.
