1. Nitrogen Fertilizer Application and Depth of Moist Soil at Planting Affected Grain Sorghum Yield The depth of moist soil before planting is critical for grain crop production in intensified dryland cropping systems. We investigated depth of moist soil at planting and nitrogen (N) fertilizer application rate effects on continuous grain sorghum yields on a Crete silt loam soil over 32-years in western Kansas. Treatments were four N rates (0, 20, 40 and 60 lb ac-1) in a randomized complete blocks design with four replication and depth of moist soil at planting determined with Paul... A.K. Obour, J.D.

2. 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
3. Soil Properties and Winter Wheat Nutrient Uptake As Affected by Long-term Tillage and Nitrogen Fertilization Knowledge gained on the long-term effects of crop management practices on soil fertility is critical in developing nutrient management strategies to optimize crop yields and environmental sustainability in semi-arid cropping systems. This study examined the long-term effects of nitrogen (N) fertilizer management and tillage intensity [conventional tillage (CT), and no-tillage (NT)] on soil properties and nutrient uptake in a dryland wheat-sorghum-fallow cropping system. Results showed winter wheat... A. Obour, J. Holman, L. Simon, Y.M. Assefa Download paper
4. Stacking Regenerative Agricultural Practices Under Irrigated Forage Production Incorporation of forage production into producer landscapes is an opportunity to hedge economic risk and increase yield stability. Regenerative agricultural management practices that also reduce N fertilizer and pest control costs, recycle nutrients, and preserve and capture precipitation are needed in semi-arid regions. There is little information on how the combination of regenerative practices such as no-tillage (NT) and cover crops will influence the timing and effect (e.g., additive,... C.E. Stewart, D.K.
