  • Rainfall and manure application timing affect organic carbon losses

    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 ...

  • Nitrogen use by warm-season grasses for biomass production

    Perennial, warm-season grasses are being evaluated as potential renewable energy crops. These species are well-suited for the production of biomass for energy applications because they utilize C4 photosynthesis and are perennial. Grasses that employ the C4 photosynthetic pathway use water, nitrogen (N), and solar radiation more efficiently than plants having the C3 pathway, and therefore are ...
