The objective of this study was to quantify the flux of greenhouse gas emissions from agricultural soil on the Texas High Plains and to identify the conservation practices and nitrogen management schemes with the best potential to mitigate the flux of these gases. In addition, yield was assessed for each of the two years, and a thorough accounting of applied nitrogen was also conducted. This study was conducted on the Texas A&M AgriLife Research station in Lubbock, Texas. Results will include cumulative flux of greenhouse gases, lint yield, and nitrogen use. Discussion will include which practices had the best ability to mitigate flux, coupled with increased or maintained yield. In addition, a discussion of the nitrogen use efficiency of each of the conservation practices coupled with nitrogen management will be included.
