Abstract
"PROCESSO PARA OBTENçãO DE GRáNULO DE URéIA COM LIBERAçãO GRADATIVA (L.G.U.) NO SOLO E PRODUTO RESULTANTE. Atuando na lixiviação e volatização, aumentando o aproveitamento do elemento Uréia nas culturas agrícolas, compreendendo um conjunto de procedimentos para criar uma proteção pelicular sobre o grânulo de uréia (A), o qual é recoberto por camadas de polímeros (B), estes por sua definidos como LGUL01, LGUS02, LGUS03 e LGUL04, 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 granulo de Uréia (A) desejado, o qual representa na prática, uma redução de 50% da quantidade de Uréia aplicado no solo, reduzindo inclusive sensivelmente as perdas volatilização ou lixiviação."PROCESS FOR OBTAINING GRADE RELEASE (LGU) UREA GRANULES IN THE SOIL AND RESULTANT PRODUCT. Acting on leaching and volatilization, increasing the utilization of the Urea element in agricultural crops, comprising a set of procedures to create a skin protection on the granule. urea (A), which is covered by layers of polymers (B), which are defined by LGUL01, LGUS02, LGUS03 and LGUL04, and for this the individual application of each of the mentioned polymers is made, where the operations of Nebulization is cumulative, meaning that each new polymer nebulization overlaps the previous coating condition until the desired Urea granule (A) product is reached, which in practice represents a 50% reduction in the amount of Urea applied. on the ground, significantly reducing volatilization or leaching losses.
