1. 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
2. Can Soil Health Metrics Improve Standard Soil Fertility Recommendations? It is commonly speculated that integrating soil health (SH) testing with soil fertility (SF) testing would improve fertilizer recommendation decisions. However, quantified impacts of SH properties, specifically soil biological properties, on fertilizer demand have not been well established. The objective of this research was to explore corn (Zea mays L.) yield response to phosphorus (P) and potassium (K) fertilization as influenced by established SF analysis and common SH metrics....

3. Effect of Seeding Rate on Annual Warm Season Forage Yield and Plant Structure Due to the decline of the Ogallala Aquifer and reduced irrigation capacity, there is growing interest in more water-efficient cropping systems in the semi-arid central Great Plains. To support the region’s livestock industry, there is increased interest in forages because they use water more efficiently than grain crops. However, there is insufficient information on summer annual forage seeding rates in the range of environments encountered in the region. The objective of this study was... J. Holman, N. Detter, A. Obour, P. Tamea Download paper
4. Summer Annual Legumes: Yield Potential and Water Use Due to the decline of the Ogalla Aquifer and reduced irrigation capacity, there is a growing interest in more water-efficient cropping systems in the semi-arid central Great Plains. One of the most water-intense crops grown on the semi-arid central Great Plains is alfalfa (Medicago sativa L.). Alfalfa is grown for its nutritive value and protein, which is highly desired by cow/calf, feed yards, and dairies of the central and southern Great Plains. The purpose of this study was to evaluate... J. Holman, N. Detter, A. Obour, L. Haag, K. Roozeboom Download paper
