Abstract:
     The present invention provides a magnesium-calcium-silicon chemical fertilizer prepared by using waste slag in iron and steel industry. Said invented chemical fertilizer is made up by using steel slag,blast furnace grain slag, calcined magnesio-dolomite offscum, vertical kiln flue ash and white residue as raw materials, and adopting such processes as breaking, screening, magnetic separation, proportioning, fine-grinding and homogenization. Said invented chemical fertilizer is low in production cost, simple in production process, can obviously raise the yield of crops of rice, peanut, maize, cane and jute, etc., and can raise their resistance to insect pest and plant diseases, and can effectively prevent soil from hardening.
