Water soluble organic carbon (WSOC) is considered the most mobile and reactive soil carbon source and its characterization is an
important issue for soil ecology study. A biodegradability test was set up to study WSOC extracted from 7 soils di erently managed.
WSOC was extracted from soil with water (soil/water ratio of 1:2, W/V) for 30 min, and then tested for biodegradability by a liquid state
respirometric test. Result obtained confirmed the finding that WSOC biodegradability depended on the both land use and management
practice. These results suggested the biodegradability test as suitable method to characterize WSOC, and provided useful information
to soil fertility.
