Although coloring materials are not essential ingredients for fertilizers，non-binding addition has certain safety risks.Scientific risk management for coloring materials could reduce the impact on the ecological environment and food safety at source.The coloring materials currently used in fertilizer production mainly involve the pigments，dyes and food colorants. Different types of coloring products have different safety levels.For example，excessive dye input into the soil may cause adsorption，degradation or bioaccumlation.Combined with the management and technical regulations of coloring materials at home and abroad，the safety risk control measures of fertilizer coloring materials are proposed in the study.It is suggested that coloring materials should be divided into three levels of“ zero risk”，“controllable risk” and“ high risk”，and that risk assessment system of product quality，biological characteristics and soil environmental should be established，so as to guide fertilizer producers to preferentially choose safe coloring materials and realize green production of fertilizer.
