Effect on the content and distribution of organic C After 28 yr of continuous cultivation of rice, the effects of winter planting of different green manures on the size of water stable aggregates of the plow layer soil were inconsistent (Table 1, Yang et al. 2012). The content of organic C of the plowed soil layer (0-15 cm depth) of long-term winter planted green manure (hereafter termed winter green manure) and of long-term winter fallow treated plots (hereafter termed winter fallow plots) differed significantly (P<0.05). The soil organic C (SOC) content was significantly higher in plots receiving winter green manure than winter fallow (P<0.05). Specifically, the SOC contents of the rice-rice-rape (R-R-RP), ricerice-Chinese milk vetch (R-R-MV) and rice-rice-ryemgrass (R-R-RG) plots were 8.0, 4.8 and 6.7% higher than those of rice-rice-fallow (R-R-WF), respectively.
