Dynamics of soil organic carbon following land-use change:insights from stable c-isotope analysis in black soil of Northeast china

Intensive soil tillage is a significant factor in soil organic matter decline in cultivated soils. Both cultivation abandonment and foregoing tillage have been encouraged in the past 30 years to reduce greenhouse gas emissions and soil erosion. However, the dynamic processes of soil organic carbon (SOc) in areas of either continuous cultivation or abandonment remain unclear and *** aims were to assess and model the dynamic processes of SOc under continuous tillage and after cultivation abandonment in the black soil of Northeast china. Soil profiles were collected of cultivated or abandoned land with cultivation history of 0–100 years. An isotope mass balance equation was used to calculate the proportion of SOc derived from corn debris (c_4) and from natural vegetation (c_3) to deduce the dynamic process. Approximately 40% of SOc in the natural surface soil (0–10 cm) was eroded in the first 5 years of cultivation, increasing to about 75% within 40 years, before a slow recovery. c_4 above 30 cm soil depth increased by 4.5%–5% or 0.11–0.12 g·kg^(-1) on average per year under continuous cultivation, while it decreased by approximately 0.34% annually in the surface soil after cultivation *** increase in the percentage of c_4 was fitted to a linear equation with given intercepts in the upper 30 cm of soil in cultivated land. A significant relationship between the change of c_4 and time was found only in the surface soil after abandonment of cultivation. These results demonstrate the loss and accumulation of corn-derived SOc in surface black soil of Northeast china under continuous tillage or cultivation abandonment.
