Abstract
Disclosed is a slow release fertilizer composition comprising a slack wax-urea adduct prepared by urea-dewaxing petroleum hydrocarbons in which the wax to urea ratio ranges from 0.08 to 0.30 and particularly intended for use on dry, desert-like soils. Solar radiation causes the wax to melt thereby slowly releasing the urea with the wax forming a biodegradable protective layer against wind erosion and water losses.
