Influence of Extractant and Soil Type on Molecular Characteristics of Humic Substances From Two Brazilian Soils
In a previous study it was observed that humic substances (HS) extracted with NaOH solution and with Na4P2O7 solution presented different molecular weights, and also that the extracted HS yield by each method varied between an Oxisol and a Mollisol from South Brazil. In the present study, we further...
