Soil organic matter as a function of nitrogen fertilization in crop successions Matéria orgânica do solo em função de adubação nitrogenada em sucessões de culturas

The interdependence between the C and N cycles is reflected by the levels of soil organic matter (SOM). SOM and organic C levels in water soluble (C-WS) humic acids (C-HA), fulvic acids (C-FA), and humin fractions (C-H) were evaluated through the classic chemical fractionation method in samples of a...
