The objective of this work was to evaluate, for two years, the acidity of the soil in a silvopastoral system, using swine wastewater, cultivating pasture and eucalyptus. Notably in relation to Brazilian pig farming, we see that the procedure is well studied as it has positive effects on national farming. The procedure has proved to be a very interesting alternative for the regulation of soil pH in situations that require intervention. The experiment was conducted at Fazenda Bonsucesso, located in the city of Uberlândia. The statistical design used was randomized blocks with 5 repetitions. The treatments applied are 5 doses of swine wastewater: 0, 200, 400, 600 and 800 m³ ha-1 year-1. The contents of macronutrients and micronutrients in the soil will be evaluated. The data were analyzed by analysis of variance verifying the significance of each variable individually for dose (ARS). With the application of ARS there was an increase in the content of K and B in the soil regardless of the dose. According to the results obtained with the application of ARS in a silvopastoral system, it was found that the dose of 200 m³ ha-1 year-1 is the most indicated.
