The objective of this research is to study the greenhouse gas emission and groundwater pollution potentials of the soils amended with raw swine soli and swine biochars made from different thermochemical conditions.  Triplicate sets of small pots were designed: 1) control soil with a 50/50 mixture of Norfolk Ap and E horizon; 2) soil amended with raw swine solid to provide 200 lb-N/ac; 3) soil amended with high-temperature swine biochar at a rate of 20 g/kg-1; and 4) soil amended with hydrothermally carbonized swine biochar (hereafter it will be called hydrochar) at a rate of 20 g/kg-1. The biochar structural properties were characterized using 13C-NMR spectroscopy. The leachates were collected and analyzed for oxygen-demanding water quality parameter (COD), nutrients (N, P, K, Na), and heavy metals (Cd, Cr, Cu, Ni, Zn).  Soil samples from the initial set up along with samples at the end of the 54-day study were analyzed for fertility. GHG emission and water quality data will be presented at the meeting.
