PROCEDURE FOR OBTAINING NITROGEN GRANULATED FERTILIZER WITH HIGH CONTENT IN MICROELEMENTS AND FERTILIZERS SO OBTAINED.

摘要

Procedure for obtaining nitrogenous granulated fertilizer with high content of microelements and fertilizer thus obtained. Fertilizers that are composed of a nitrogen-based raw material, preferably dissolved ammonium nitrogen or liquor, another raw material with a high content of chelated trace elements or in the form of sulfates such as metal sulfate as a byproduct in obtaining titanium dioxide and finally another High magnesium content such as calcined magnesium oxide. Optionally, other raw materials such as phosphorus and potassium base can be added. In the process of obtaining the sulfate is neutralized with magnesium oxide, and the nitrogenous base is added in a conventional granulator, forming the granules, drying them and rejecting to re-crush those granules having certain dimensions.
