In an experiment on soil management systems implemented in 1988 at the experimental station Fundação ABC, Ponta Grossa, in the central South region of the State of Paraná, inorganic N dynamics were examined to find a soil management strategy with a view to a sustainable environment.
The objective of this study was to calculate the net mineralization and nitrification rates of soil N and the correlation with soil pH under management systems.
