    Fluorescence analysis of humic-like substances extracted from composts: influence of composting time and fractionation

    Humic-like acids (HLA0, HLA70, HLA130, HLA730) were extracted from composts obtained from sewage sludges and trimmings after 0, 70, 130 and 730 days of composting, respectively. In addition, HLA130 was fractionat...
