Disponibilidade de nitrogênio pela oxidação do carbono lábil com permanganato de potássio

Abstract: Availability of nitrogen by the oxidation of the labile carbon with potassium permanganate Abstract: The present work had the objective of evaluating the liberation of the nitrogen associated to the labile carbon oxidized with KMnO 4 (333 mmol L -1 ) and to verify the supply capacity of nitrogen by its correlation with the nitrogen absorbed by the plants. The soil used belongs to a Cambic Yellow Red Podzol, cultivated with corn since 1984, and its productivity is being evaluated as a function of the doses of 0… Show more
