METHODS OF COATING SEEDS AND A COATING COMPOSITION

摘要

Plant seeds, preferably leguminous, are coated with 0.1-5 parts by weight, per 100 parts by weight of seed, of a film forming material and further coated with at least 10 parts by weight (same basis) of solid particles of an agent such as calcium carbonate while the first cost is semi-solid and tacky. The film-forming material preferably comprises a prepolymer curable with water and/or an amine to a water insensitive but permeable solid. One particularly suitable agricultural use for the resulting coated seeds is in the growing of crops in acid soils.
