In the process of chemical fertilizer storage,we find due to the various factors such as humidity,pressureand temperature,the fertilizer produces different degrees of clumping,and as time goes on the clumping situationbecomes more and more serious which causes the inconvenience of fertilization and transportation and increasing inlabor intensity. In this paper,a low cost,safe and environmental protection of anti-caking agent for fertilizers isdeveloped. The experiment of adding the anti-caking agent in compound fertilizer and ammonium bicarbonate showsthat after adding the anti-caking agent,their free water content is reduced. And compared with the fertilizer without anti-blocking agent,the lumps of fertilizers is significantly reduced. The effect of preventing fertilizer caking is remarkable.
