Soil dissolved organic carbon （DOC） is essential for soil fertility and environmental health. Currently several different methods are available to measure soil DOC, which lead to poor comparability for soil DOC levels. Here, we used four methods, i.e., total organic carbon（TOC） analyzer method, volumetry method, ultraviolet absorption method, and colorimetric method, to determine DOC concentration in fresh soil extracts. In total 46 fresh soil samples from profiles which were belonged to 6 soil genuses developed in hills and mountains in mi...
