The confinement of pigs stands out as a great generator of swine wastewater (SW). The final destination of waste generated is currently a concern of society, since if handled improperly, it can cause serious impacts to the environment. One of the alternatives is the use of SW as a source of nutrients, which are made available to the plants, after the mineralization of organic matter. The objective of this work was to compare soil chemical attributes under two planting arrangements, in single and double lines of Corymbia citriodora. Two experiments were carried out at the Bonsucesso farm, in Uberlândia-MG, the first with C. citriodora in simple lines, with five plants per plot, spacing two meters between plants and 15 meters between rows. The second experiment was with C. citriodora in double lines, with two meters between plants in the line, three meters between lines in the plot and 15 meters between the double lines of C. citriodora. The statistical design was in randomized blocks. The treatments used were five doses of SW (0; 200; 400; 600 and 800 m³ ha-1) with five replicates. The application of SW rates was divided in the dry season, in the months of June, July and August. The chemical characteristics of the soil were evaluated in the 0-20 cm depth layer. Planting on double lines of C. citriodora provided higher soil nutrient contents. The application of swine wastewater raised the levels of potassium and heavy metals such as copper and zinc. The dose of 200 m3 ha-1 provided adequate levels for most nutrients present in the soil.
