Abstract
"PROCESSO PARA OBTENçãO DE GRANULO DE FóSFORO COM LIBERAçãO GRADATIVA (L.G.P.) NO SOLO E PRODUTO RESULTANTE". A fim de eliminar a fixação do fósforo por precipitação e por adsorção, aumentando o aproveitamento do elemento fósforo nas culturas agrícolas, compreendendo um conjunto de procedimentos para criar uma proteção pelicular sobre o granulo de fósforo (A) , sendo este granulo formado por Super Fosfato Simples, Super Fosfato Triplo , MAP ou DAP(A), o qual é recoberto por camadas de polímeros (B), estes por sua definidos como LGPL01, LGPS02, LGPS03 e LGPL04, sendo que para tal se faz a aplicação individual de cada um dos polímeros citados, onde as operações de nebulização são acumulativas, ou seja cada nova nebulização de polímero sobrepõem-se à condição anterior de recobrimento, até que se chegue ao produto grânulo de fósforo (A) desejado, o qual representa na prática, uma redução de 50% da quantidade de Fósforo aplicado no solo, reduzindo inclusive sensivelmente as perdas por adsorção."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.
