Project Number: 1902-21000-008-10
Start Date: Sep 01, 2012
End Date: Sep 30, 2015
Soil respiration and N2O and CH4 emissions will be monitored on switchgrass that will receive biochar at 10 Mg/ha in one application prior to planting or at 2 Mg/ha in each of five annual applications. Soil carbon (C) and nitrogen (n) N content will be monitored annually to a depth of 1.0 m. A life cycle assessment of greenhouse gas sources and sinks for each system will be conducted. Additional data to be collected will include volumetric soil water content, bulk density, air temperature, solar radiation, and rainfall. Weather data will be collected continuously during the growing season. Algorithms will be developed to quantify the effect of biochar on the measured soil properties.
