Long-Term Trends in Nitrous Oxide Emissions, Soil Nitrogen, and Crop Yields of Till and No-Till Cropping Systems

No-till cropping can increase soil C stocks and aggregation but patterns of long-term changes in N(2)O emissions, soil N availability, and crop yields still need to be resolved. We measured soil C accumulation, aggregation, soil water, N(2)O emissions, soil inorganic N, and crop yields in till and n...
