The Texas High Plains serves as a model region when studying factors affecting agricultural sustainability with respect to water, soil, nutrients, energy, and community stability. In this semi-arid region, agriculture accounts for over 40% of the economy but depends heavily on irrigation from the Ogallala Aquifer at non-sustainable rates of use. This project entailed the first 3 years (2011 to 2014) of maintenance for the Texas Tech Research Station at New Deal, TX, to preserve basic long-term research facilities, support forage and livestock systems research, and to serve as a bridge between research and outreach to producers. Historically severe droughts in 2011 and 2012 prevented adequate forage production to support grazing research, and grazing was further postponed in 2013 to allow pasture recovery, elimination of bermudagrass, irrigation system repair, and installation soil moisture monitors. Results of an associated 9-year outreach project on irrigation conservation (Texas Alliance for Water Conservation) were summarized and submitted to the Texas Water Development Board. Alfalfa and sweet clover were successfully interseeded back into old world bluestem pastures where severe drought had reduced the legume content. Research in 2013-2014 comprised a Master’s thesis study on the use to digital image analysis for tracking grass ground cover, leaf area, light interception, and forage yield. That work continued in 2014 as part of doctoral research to refine a simulation model for predicting grass growth in response to water supply and hay vs. grazing management. New grazing research was initiated with steers in 2014 to study the effects of alfalfa on cattle weight gain in old world bluestem pastures at low water input. Another study characterized insect populations in old world bluestem and alfalfa pastures and on cattle flies to test whether old world bluestem deters potentially harmful insects. Early testing of the suitability of teff grass indicates its great potential as a summer annual grass for hay and grazing under limited water supply.
Project objectives:div style="margin-left:1em;">
The overall objective of our project is to (1) understand the biological, environmental, social, economic, and policy issues impacting agricultural sustainability in the Southern High Plains, and (2) translate research into adoption of more sustainable practices. Furthermore, we aim to transfer new knowledge into adoption of ecologically and economically sustainable crop production practices that use available water at maximum efficiency. The specific objective of this funding (2011 to 2014) was to provide supplies, equipment, and maintenance for the Texas Tech University New Deal Research Station to preserve basic long-term research facilities, support forage and livestock systems research, and to serve as a bridge between research and outreach to producers.
The performance targets were to 1) maintain productive stands of forages for testing their adaptability, animal production, and water use, 2) receive and manage beef cattle for grazing trials, 3) maintain infrastructure for irrigation systems, fencing, weather recording, roads, and stock waterers, controlling pests, 4) monitoring and correcting soil fertility deficiencies, and 5) conduct educational and demonstration activities related to the research and outreach missions.
