Controle da Qualidade dos Principais Fertilizantes na Região de Rondonópolis

Abstract

The increase in the emergence of industries and agricultural growth made the city of Rondonópolis, located in the southeastern region of the state of Mato Grosso, a highlight in the state's economy. Verification of the quality of agricultural products is necessary for efficient and sustainable production. As a source of contamination, fertilizers with high concentrations of toxic heavy metals have been a matter of concern and identified as one of the obstacles to sustainable food production. On the other hand, there is a growing demand for better quality agricultural products, with higher micronutrient content and less anti-nutritional factors, such as toxic heavy metals. Mato Grosso, being one of the richest and most diversified states in Brazil, has a concern in this sector to consider. Rondonópolis is considered the agro-industrial pole of the State, given the large number of companies from different sectors involved with soy and a significant increase in the industrial sector in the production of fertilizers. Fertilizer quality control is a necessary strategy for maintaining or increasing agricultural production, given the importance of food safety and its ability to adequately provide nutrients to animals and humans, avoiding contamination by heavy metals. The present study was carried out in a laboratory in order to verify the quality of the content of the following metals: Cd, Pb, Hg, Cr, As, Mo, Co and Ni in different types of fertilizers and agricultural correctives, marketed and produced in the city of Rondonópolis, through the METHOD 3050B method by acid digestion of sediments, sludge and soils (Acid Digestion of sediments, Sludges and soils), following all the guidelines contained in EMBRAPA IN 27. The results showed that all samples analyzed were within the range established by the aforementioned standard.
