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

摘要

"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.
