The results show that while the major composition of organic matter of sorbent consists of humic acid(Chelsea soil),sorption of phenanthrene for soil sample is easy to get equilibrium and no clearly hysteresis exists between sorption and desorption.

Seasonal variation of light fraction organic matter in degraded red soil after vegetation restoration;

In this article, we reviewed the latest studies of the sensitive evaluation indicator of effects of land-use change on the soil carbon pool, including the microbial biomass carbon and microbial quotient, CO2 flux and qCO2, light fraction organic matter and particulate organic matter, and dissolved organic carbon.
