Cana-de-açúcar: o uso de fertilizantes e os impactos ambientais

Abstract

The excessive use of mineral fertilizers in sugarcane cultivation can cause environmental problems related to soil, water, and air quality. This work aimed to characterize the fertilizers used in this crop and the impacts associated with it through the scientific literature. For this, Google Scholar searches were performed using specific keywords and selecting only scientific literature that included field visits and reported environmental impacts. The information taken from the scientific literature to be analyzed were year, place (country), biome, soil type, cultivated variety, fertilizer brand, concentration of macronutrients and micronutrients, unit of measurement of fertilizer application (units of mass per unit of area), formulation used, type of environmental impact described, type of micronutrient, concentration of micronutrient. The results indicated that the most accomplished publication format on the subject was article, the years that stood out were 2011, 2012, 2016 and 2019, the country that most published was Brazil, which may be related to the region and the type of soil most used which was the tropical and the red latosol. In addition, the cultivated varieties were diversified for each work, the chemical component most used as fertilizer was urea, which is directly related to the most cited environmental impact in the scientific literature, which were greenhouse gases. It is concluded that the scientific production on the subject is reduced, in addition to the fact that one of the problems most associated with the use of fertilizers is greenhouse gases.
