1. Precision Mapping Technology in Dryland Cropping System Increasing availability of cropland geospatial data are providing farmers with opportunities but also challenges in interpreting these data for precision cropland management decisions. The objective of this study is to evaluate spatial variability and precision management decisions using mapping technology in dryland cropping system. The study was initiated in 2018 in Akron, Colorado on field size plots ranged from 2.4 to 4.5 ha (6-11 acres) with substantial production variability. ... M.M. Mikha, D.M. Barnard, K.R.

2. Effects of Climate Change and Narrow Rows with Higher Plant Densities on Yields of Irrigated Corn Climate change is significantly impacting agricultural systems worldwide, and although there are reports of these impacts contributing to higher yields in some regions, the general consensus is that there will be negative impacts on yields and soil quality across large regions. Management practices that can contribute to higher yields and adaptation to a changing climate will be important during the 21st century. This presentation will cover results from two manuscripts that are current... J.A. Delgado, B. Floyd, R. D'adamo, A. Villacis, A.D. Brandt, A. Halvorson, C.E. Stewart, J. Alwang, S. Del grosso, D.K.

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 t... S. Del grosso, J. Derner, J. Delgado Download paper
4. Measuring N2O Emissions from Dryland Sorghum Production Using Gas Chamber and Eddy Covariance Flux Methods Nitrous oxide (N2O) emissions are not well quantified in the dryland production systems of the Great Plains. Lack of field-based data has led to the use of questionable assumptions in various life-cycle analyses when dryland grain production is a feedstock. A field-scale trial of 81 acres was established within a 160 acre production field of dryland grain sorghum in northwest Kansas in 2021. Grain sorghum was no-till seeded into wheat stubble. Grower practices for nitr... L. Haag, P. Tomlinson, S. Patel, E. Santos Download paper
