Full text not available from this repository. (Request a copy)Abstract
Humic acid (HA) and fulvic acid (FA), key passive fractions of soil organic matter, differ in molecular size and solubility, contributing to long-term carbon sequestration and nutrient exchange, and are extracted using base–acid fractionation. Their characterization provides insights into soil quality, carbon stability, and nutrient availability.
