ORGANIC MATERIAL FERTILIZER COMPRISING N-GUANO AS MAJOR INGREDIENT

摘要

An environment-friendly organic fertilizer is provided to have excellent base manure and additional fertilizer effects and a broader application period and prevent the occurrence of soil salinity caused by nitrate and various insoluble salts. An environment-friendly organic fertilizer is obtained by blending 50-99 parts by weight of nitrogen guano with 1-50 parts by weight of at least one selected from sulpomag, natural MOP, or natural SOP. The organic fertilizer is prepared by the steps of: mixing the nitrogen guano with the sulpomag, natural MOP, or natural SOP homogeneously in a predetermined weight ratio; charging the mixture into a pelletizer to obtain pellets; and drying and cooling the pellets.
