| Research Abstract |
Humic substances are dark-colored amorphous organic matter derived from the microbiological decomposition of plant materials and the composting process. In soils, easily extractable humic substances are considered to be playing important roles in the mobilization of plant nutrients and metal ions. In this study, the chemical properties of easily extractable humic substances and their fate in soils were revealed.
