Study of agricultural watersheds and carbon losses
Date:6/19/2009

MADISON, WI, JUNE 15, 2009 Dissolved organic carbon (DOC) losses from tile drains are an underquantified portion of the terrestrial carbon cycle. This is particularly important in the eastern corn belt where tile drainage dominates the agricultural landscape. Specific land management practices, such as manure application, can play a large role in the export of DOC as soluble organic carbon is applied to or injected into the soil surface. As animal agriculture intensifies in the upper Midwest, measuring DOC exported through tile drains is important when evaluating carbon budgets and carbon sequestration potential.

Scientists at Purdue University have investigated the impacts of manure application, crop rotation, and nitrogen application rate on DOC losses from tile drains. Research was conducted over a six-year span (1998-2004) at Purdue University's Water Quality Field Station, which was designed specifically to measure drainflow and solute losses from agricultural practices. Forty-eight drainage lysimeters were established at the field site in 1992. Twelve field treatments included a restored prairie grass, continuous corn rotations and cornsoybean rotations fertilized at three nitrogen rates, and continuous corn rotations fertilized with lagooned swine effluent applied in the spring or fall of each year. The study was funded by the USDA through Consortium for Agricultural Soils Mitigation of Greenhouses program and through the CSREES-NRI Watershed Processes and Water Resources Grant; the results were published in the May issue of the Journal of Environmental Quality.

The study determined that annual losses of DOC were not affected by any crop management practice. However, when drainage-inducing rainfall occurred with one month of manure application, the monthly DOC concentration of the manured plot was greater than that of non-manured plots. Overall, drainage hydrology was determined to be the largest sole driver of DOC loss. Great
