Internal anti-caking agent is mainly used in the production process of inorganic fertilizer anti-caking agents manufacturers can improve moisture (relative humidity increase the critical sales inorganic anti-caking agent, or slow absorption rate); increase the strength of the fertilizer granules , roundness, or change crystal morphology [38]. Studies have shown that certain inorganic substances such as aluminum sulfate (Mg), potassium nitrate (magnesium, aluminum), ammonium polyphosphate (potassium), boric acid, copper oxide (iron, aluminum, magnesium) salts and other anti-caking agents guaranteed, and Certain organic compounds, such as p-toluidine, azobenzene, etc., to prevent caking of fertilizer has a role [26, 32]. In recent years, China's fertilizer industry is developing rapidly, but fertilizer caking issue has been one of the important factors that affect the quality of fertilizers.
