Estudo de amostras de calcário de indústrias do estado de Mato Grosso

Abstract

Agricultural limestone improves the chemical and physical characteristics of soils, as Brazilian production is severely limited because of the toxic elements and acidity that occur in Brazilian soils. The present work aims to analyze and evaluate the results obtained from analyzes carried out in the laboratory to determine the percentages of calcium and magnesium oxide contents, neutralizing power (PN) and also the percentages of passing material in the granulometric analysis. The analyzes were carried out in the limestone and fertilizers laboratory of the company Agroanálise Laboratorios Intregrados, located in the city of Cuiabá in the state of Mato Grosso, and several samples of calcitic, dolomitic and magnesian limestone were received from five large limestone industries in Mato Grosso, noted In the analysis, the diversity of results for each type of sample was observed, where some companies presented CaO% and MgO% contents in their samples outside the established standards, most of the samples presented excellent results, with acceptable values and within the standards From the literature, it is up to the buyer to analyze and seek knowledge and, if necessary, professionals to analyze which product from these companies is best for their soil and planting.
