| Abstract: | Light fraction organic matter is largely composed of plant residues at various stages of decomposition and a lot of microbial debris. Soil fertility varies with its changes as indicators. The isolation method and the composition of light fraction, the effect of planting and fertilization on the light fraction, the distribution of light fraction in soil aggregrates and soil profiles as well as the seasonal changes of light fraction were reviewed in this paper. |
