PURPOSE: Provided is a preparation method of fertilizer which contains abundant organic materials and calcium element from potassium feldspar and thus enhances the growth of lawn and prevents soil acidification and water pollution. CONSTITUTION: A preparation method of fertilizer is characterized by: mixing potassium feldspar sand with fowl excrement, leaf mold; adding CMC(carboxylmethyl cellulose), sodium polyacrylate and charcoal powder; and further adding sesame pulp and shell lime. Wherein the potassium feldspar sand has 0.92-0.93 of emission ratio of far infrared ray at 5-20 micrometer wavelength, and consists of 66.56wt% of SiO2, 18.36% of alumina(Al2O3), 11.83wt% of potassium oxide(K2O), 2.42wt% of sodium oxide(Na2O), 0.08wt% of ferric oxide(Fe2O3), 0.06wt% of manganese oxide(MnO) and other miscellaneous elements such as cerium, selenium, cobalt, radon and the like.
