Total and Active Soil Organic Carbon from Long-term Agricultural Management Practices in West Tennessee
Soil organic carbon (SOC) content is strongly influenced by agricultural management practices. Leveraging three long-term field experiments in Tennessee, this study analyzed the effect of crop rotation, tillage, and cover crops on SOC and permanganate-oxidizable C (POXC) at various soil depth increm...

Leveraging three long-term field experiments in Tennessee, this study analyzed the effect of crop rotation, tillage, and cover crops on SOC and permanganate-oxidizable C (POXC) at various soil depth increments (0–2.5, 2.5–5, 5–7.5, 7.5–10, 10–15, 15–22.5, 22.5–30, 30–45, and 45–60 cm), as well as at the 0- to 15-cm profile. Corn ( L.) and cotton ( L.)–based systems showed increased SOC from 0 to 22.5 cm compared with soybean [ (L.), Merr.]–based systems. Additionally, no-till systems accumulated more SOC than tilled systems from 0 to 5 cm, but cover cropping showed no effects.
