摘要:
Various groundwater table levels in paddy soil aggravate the complexity of soil organic carbon (SOC) sequestration under redox conditions. We investigated a long-term experimental field consisting of two groundwater tables (SWT, shallow groundwater table; DWT, deep groundwater table) and three straw application rates (NPK, without straw return; LOM, low rate of straw return; HOM, high rate of straw return). Soil samples from 0–10, 10–20 and 20–40 cm soil layers were collected and analyzed. Results revealed that SOC fraction contents signifi...
