process for obtaining gradually released phosphorus granules (l.g.p.) in soil and resulting product

摘要

"PROCESS FOR OBTAINING GRADE OF PHOSPHORUS GRANULES (L.G.P.) IN SOIL AND RESULTANT PRODUCT". In order to eliminate phosphorus fixation by precipitation and adsorption, increasing the use of the phosphorus element in agricultural crops, comprising a set of procedures to create a skin protection over the phosphorus granule (A), this granule being formed by Super Phosphate Single, Triple Super Phosphate, MAP or DAP (A), which is covered by layers of polymers (B), which are defined by LGPL01, LGPS02, LGPS03 and LGPL04. cited polymers, where nebulization operations are cumulative, ie each new polymer nebulization overlaps with the previous coating condition until the desired phosphorus granule (A) product is reached, which in practice represents a reduction 50% of the amount of phosphorus applied to the soil, significantly reducing the losses by adsorption.
