ABSTRACT:
A composition comprising lignosulfonate, sugar and optionally urea useful in preventing the formation of dust and caking of granular fertilizer particles. The composition has a lower viscosity at room temperature, is more effective in preventing dust and caking than lignosulfonate, urea, or sugar alone or mixtures of lignosulfonate and sugar, and mixtures of lignosulfonate and urea. The composition is preferably sprayed on the fertilizer after granulation, or when blending of the fertilizer particles is completed.
