1. Assessment of Long-term Effects of Tillage and Nitrogen Management Practices on Irrigated Corn Yields and Nitrogen Use Efficiencies Corn grain yields and crop nitrogen uptake are affected by management factors such as tillage intensity and nitrogen rates. Additional data about the long-term effects of tillage and nitrogen rates on yields and nitrogen use efficiencies of irrigated corn are needed. We are presenting preliminary results from a 17-year study about the effects of these management practices on irrigated corn yields and nitrogen uptake in a Fort Collins clay loam soil at Colorado State University’s Agricultural...

2. Nitrogen Fertilization and Long-term No-tillage Impacts on Soil Properties and Deep Soil C Storage Under Irrigation The net soil greenhouse gas mitigation potential of conservation agricultural management practices is strongly influenced by the direction and magnitude of soil organic C (SOC) change in deep soil layers (>6”). Deep SOC is typically old, highly processed, and consists of microbial products and root exudates associated with clay and other minerals. However, it can be susceptible to decomposition and priming from the addition of new, labile organic C. We examined long-term soil C dynamics... C. Stewart, D. Manter, J. Delgado, S. Del grosso, F.

3. Legacy Impacts of Cattle Grazing on Soil N2O and CH4 Fluxes in Shortgrass Steppe Grazing cattle directly emit CH4 from enteric fermentation and contribute to soil N gas emissions related to nitrogen and organic matter additions from urine and manure deposits. Grazed soils can be sources or sinks of CH4, depending on moisture levels and localized manure patches. N2O emissions are related to availability of water as well as mineral N and labile C substrates in soil. Previously, we observed higher N2O and NH3 losses from fresh patches of urine and manure compared to... S. Del grosso, J. Derner, J. Delgado Download paper
