Abstract
Suspension fertilizers containing humic acid as a crystallization inhibitor and crystal growth modifier. Suspension fertilizers containing from 0.05% to 3% humic acid and from 0.25%-3% bentonite have excellent stability as evidenced by a low concentration of crystals, a low crystal growth rate, good suspension characteristics and good rheological properties. An improved method of manufacturing suspension fertilizers which consists of adding from 0.05% to 3% by weight humic acid to the suspension fertilizer, and a method of inhibiting the formation and growth of crystals from a supersaturated solution of at least one fertilizer chemical which comprises adding from 0.05% to 3% by weight humic acid to the solution before it becomes supersaturated.
