Resumen
Soy is a product of agriculture that has a diversified use as food or raw material for derivatives such as oil and bran. There are studies evaluating the effect of residual vegetable oil on soil and other natural resources. However, environmental impact studies of refined soybean oil were not found in the literature. Thus, due to the large production volume of refined soybean oil, this work aims to investigate the response of earthworm escape, simulating the inadequate disposal of this residue in sandy and clayey soil. A completely randomized design with seven treatments consisting of doses of refined soybean oil added to the sandy and clayey soils was used: T1 - 1.0 mL; T2 - 10.0 mL; T3 - 15.0 mL; T4 - 20.0 mL; T5 - 25.0 mL; T6 - 30.0 mL and T7 - 100.0 mL in triplicate. The results show that for 15 mL and 20 mL doses, the refined soybean oil promoted a deleterious effect on the sandy and loamy soils, respectively, causing at least 60% of the earthworms to escape.
