PROCESS FOR PRODUCTION OF GRADUALLY RELEASED FERTILIZER CONTAINING UNIFORM QUANTITIES IN EACH MACRO AND MICRO NUTRIENT GRAIN MAY BE OBTAINED BY COATING OF GRANULATED FERTILIZERS AND POSTERIOR FERTILIZERS PERSONALLY POSTERIORIZING BY FERTILIZER MORE AGRICULTURAL ADDITIVES

摘要

The present invention is in the field of sustainable agriculture referring to a process of gradual release granulated fertilizer production. One of the process routes, called coating, is the mixture of one or more fertilizers to be coated with agricultural additives. In the granulation route, both powdered fertilizers and agrifineral additives are granulated together. agromineral additives used in the present invention comprise rocks containing any type of macro or micronutrient, such as, for example, green arene-pelitic rhythmite and / or green glauconitic and / or green siltstone and / or green metasilite and / or verdigris type rocks. and / or potassium and phosphate rocks generally. In the present invention it is possible to incorporate powdered macro and micronutrients on the surface of the granules to be coated with agromineral additives in order to obtain a high agronomic efficiency fertilizer product. Granular materials such as urea, simple superphosphate, triple superphosphate, mono-ammonium phosphate, kcl may be employed as coating fertilizers, as well as alternative fertilizers and other materials that perform functions of interest to soil or plants.
