Synthetic inorganic chemical fertilizers are treated with lignosulfonate to harden and provide anti-caking and anti-dusting properties to the fertilizer particles. The fertilizer/lignosulfonate mixture includes up to about 5.0% by weight lignosulfonate on fertilizer. An improved method of treating inorganic fertilizers with lignosulfonate is also disclosed.
