From: Soil moisture and soil organic carbon coupled effects in apple orchards on the Loess Plateau, China
The relationship between SMC, SOC, SMDE, SOCSE and RDWD in the apple orchard varies with stand age. (*p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001). The SMC, SOC, SMDE, SOCSE and RDWD represent soil moisture content, soil organic carbon, soil moisture deficit effect, soil organic carbon sequestration effect and root dry weight density, respectively.
