Abstract
A coated granular fertilizer which comprises a degradable film containing 10% by weight or more of a polyolefin and/or petroleum wax having a weight-average molecular weight of 300-10,000 and an inorganic filler and/or a surface active agent and a granular fertilizer coated with said degradable film.
Claims9
A coated granular fertilizer which is coated with a single layer coating of a degradable film containing 10% by weight or more of a polyolefin and/or petroleum wax having a weight-average molecular weight of 300-10,000, an ethylene-vinyl acetate copolymer and/or an ethylene-α-olefin copolymer having a weight-average molecular weight of 20,000 or more, a ratio of weight-average molecular weight to number-average molecular weight of 1-3 and a density of 0.8-0.9 g/cm3, and/or an ethylene-vinyl acetate copolymer and an inorganic filler and/or a surface active agent, the weight ratio of the ethylene-vinyl acetate copolymer and/or ethylene-α-olefin copolymer to the polyolefin and/or petroleum wax being 0.01-2.0.
