Improvement introduced in a protected urea manufacturing process for use as fertilizers in the production of formulations containing macro and micronutrients used for covering or planting annual and perennial crops.
"IMPROVEMENT INTRODUCED IN THE MANUFACTURING PROCESS OF UREA PROTECTED FOR USE AS FERTILIZERS IN THE PRODUCTION OF MACRO AND MICRONUTRIENT FORMS USED IN THE COVERAGE OR PLANT OF ANNUAL AND PERENNAL CROPS". Characterized by the fact that it comprises: a process where protected urea is a product obtained by extruding the starch mixture, urea, which may contain macro or micronutrients, and in the extrusion process occurs the pre-cooking of starch under high temperature and pressure, where the urea molecule and the other nutrients are retained by the characteristic gelatinized starch that gives the product great stability and that in the soil can present a slow and simultaneous degradation of its components, and when applied to the soil surface the process of urea hydrolysis occurs. slower, allowing greater N infiltration into the soil profile reducing volatilization losses, thus by retaining N more strongly the protected urea applied at planting would release N more slowly in small amounts, reducing losses from leaching and volatilization. .
