Due to the characteristics of Brazilian soils, pH correction is necessary to improve agricultural productivity. With the increase in pH, there is an increase in the levels of basic nutrients and the simultaneous insolubilization of others that can be toxic to cultivated plants. In this context, the most used product is limestone. Other compounds, like plaster agricultural, a by-product of phosphoric acid production have been used frequently. In this logic, the by-product generated in the production of the sulfocalcic syrup, as it contains high amounts of sulfur and calcium in its composition, in addition to other nutrients in lesser quantities, and to a high alkalinity, presents itself as a potential compound for its application in agricultural soil, due to the benefits it can offer to the soil and plants.Therefore, the objective of this study was to carry out an evaluation of the potential application of solid waste from a fertilizer production industry, associated with limestone, as a corrective for agricultural soil. Based on the study, it was observed that the lower the limestone content used in the treatments, the lower the power to correct soil acidity. The length and dry mass of the plants are within the desired standards for harvesting and in relation to the levels of micro and macronutrients extractable from the soil and plant tissue, in both cases, some nutrients were in excess, which shows the need for more in-depth studies so that it only benefits the soil with the nutrients in its composition, without being made available in excess to the crops so that there is no damage in their development.pt-BREngenharia QuímicaResíduos sólidosAcidez do soloTratamento de resíduosTrabalho de Conclusão de Curso
