Abstract:: Biochar is a highly porous, carbon-rich residue produced by thermochemical conversion (pyrolysis) of plant biomass and carbonaceous organic materials under oxygen-controlled conditions. Chars produced by this process tend to have high ion-exchange capacities and, when added to soil, increase retention of water and nutrients and improve soil aggregation, porosity, and...

Abstract:: In order to properly utilize organic amendments as nitrogen sources, reliable methods to estimate plant-available nitrogen (PAN) are needed. The objectives of this study were to (1) evaluate the use of crop and soil responses in fertilizer N equivalence (FNE) calculations, (2) examine the relationships between the C/N ratio, total...

Creator:: Wanzek, Thomas
Abstract:: Soils have a critical role in global carbon (C) cycling, containing one of the largest fast-cycling carbon stocks on earth. Robust representation of soil organic matter dynamics in Earth System Models is critical for future climate prediction. Current C cycling models assume that all C cycling in non-hydric (i.e. ‘upland’)...

Creator:: Kirkpatrick, Molly C.
Abstract:: The archaeological record of the First Americans is known almost exclusively from interior sites located away from coastal margins. While archaeologists hypothesize that early peoples initially migrated into the Americas along the Pacific coast, environmental changes associated with postglacial sea level rise may have destroyed or obscured such early sites....
