“…High demand for vegetable protein and favorable economic condition enables the expansion of soybean cultivation in areas that were not traditionally cultivated, i.e., the lowland areas in southern Brazil (Rocha et al, 2017;Sartori et al, 2016), entailing 1/3 of the area traditionally sown with irrigated rice (IRGA, 2019). In addition, crop rotation is an alternative to control weed infestations (Scherner et al, 2018;Fraga et al, 2019), break pest and disease cycles, improve soil conditions for plant development and increase the sustainability of the system (Goulart et al, 2020) Imperfectly drained soils (Planosols) predominate in these areas due to the water table being close to the surface (Streck et al, 2008).…”
