Abstract

A fertilizer is rendered non-dusting and non-caking by coating with 0.01-0.6% of an isomerized drying polyene polymer. The polymer may be obtained from isoprene, piperylene, cyclopentadiene, cyclohexadiene-1,3, butadiene, 3 - methylheptatriene - 1,4,6, or n - decatriene-1, 5,9. It may be copolymerized with up to 50% of ethylene, propylene, butylene, isobutylene, vinyl-acetylene, styrene, a -methylstyrene, or acrylonitrile. It may also contain up to 50% of a polymer which is incapable of further polymerization, e.g. polystyrene or polyacrylonitrile. It may have a molecular weight of 500-40,000. Isomerization may be effected before, during or after coating. The fertilizer may contain ammonium, potassium, calcium, copper, manganese, zinc, phosphate, nitrate, chloride, sulphate, carbonate, or urea. It may be in granules having a diameter of 2-4 mm.
