Comparison of carbon and nitrogen determination methods for samples of a Paleudult subjected to no-till cropping systems Comparação de métodos de determinação de carbono e nitrogênio em amostras de Argissolo sob plantio direto

Organic carbon (C) concentration evaluated by the Walkley-Black method, and total nitrogen(N)concentration determined by Kjeldahl method, were compared with corresponding results of C and N concentrations obtained through the dry combustion method (Elementar Vario EL analyzer), using samples of ten...
