Summary
The biogeochemical impacts of alternative management practices for a row-crop field in Iowa were modeled. Numerous field measurements were made to quantify the impacts of no-till on crop yields, soil organic carbon (SOC) dynamics, nitrate leaching, and trace gas emissions. The observations provided first-hand information to understand the comprehensive effect of an alternative tillage method on agricultural production and the environment. Field observations indicated that the impacts of no-till on the Midwestern agro-ecosystems were highly variable in space and time due to the companion management practices, as well as the climatic and soil conditions. The modeled results indicated that the best management practices systems could be [...]
Summary
The biogeochemical impacts of alternative management practices for a row-crop field in Iowa were modeled. Numerous field measurements were made to quantify the impacts of no-till on crop yields, soil organic carbon (SOC) dynamics, nitrate leaching, and trace gas emissions. The observations provided first-hand information to understand the comprehensive effect of an alternative tillage method on agricultural production and the environment. Field observations indicated that the impacts of no-till on the Midwestern agro-ecosystems were highly variable in space and time due to the companion management practices, as well as the climatic and soil conditions. The modeled results indicated that the best management practices systems could be achieved by combining no-till with other management practices, in accord with local soil and climate conditions.
