Soil Carbon Alterations with Management Changes

view full-size image

Cultivation generally leads to reduction of soil organic carbon, which, without offsetting practices, is exacerbated by corn-stover removal. A mechanistic understanding of long-term harvesting effects on soil fertility and other aspects of sustainability is essential for predictive models and monitoring procedures.
