Topsoil and Deep Soil Organic Carbon Concentration and Stability Vary with Aggregate Size and Vegetation Type in Subtropical China
Fig 2
The organic carbon concentration and mineralization of aggregate soil within 71 days at various soil depths in two restored plantations of subtropical China.
Error bars show the standard error of the mean. The different letters represent significance differences among the different soil aggregate fractions within a depth at P<0.05 level.
