The management system normally affects soil nutrient availability, as a consequence of tillage practices, crop rotation and crop residues remaining in the cultivated area. The objective of this study was to evaluate the alterations in cation availability in two Oxisols in the Brazilian Cerrado under conventional and no-tillage systems for more than 10 years. The experiments were conducted in Costa Rica, state of Mato Grosso do Sul, and in Luziânia, Goiás. Both soils were Oxisols, but one being a Red Latosol […]
