Education Training

Evaluating Alternative Meteorological Data Sources for Potential Use in Irrigation Management   Carefully selected alternative data sources can complement agricultural weather station networks, provided data and siting biases can be addressed adequately through calibration and associated data techniques. Machine learning methods can be helpful in filling spatial data gaps.  

Educational video and slide show content addition to OAP and TXHPET Web sites   A two-year project to develop educational digital media addressing Ogallala water use issues for Texas High Plains agricultural producers has demonstrated that online outlets are an effective means for dissemination.   

Cotton irrigation for sustainable production in a thermally limited region   Irrigation of 5 to 7 inches, depending on rainfall, produced 2.5 bales of cotton in Southwestern Kansas. Factors limiting cotton are total growing degree days and hail storms.   

Field Evaluation of Center Pivot Nozzle Package Application Intensity   A tipping bucket rain gauge was added to the data collection set during linear and center pivot uniformity evaluations. The collected data are consistent with industry ranges of application rates for particular nozzles and configurations.  

Training, user feedback, testing, economic impact, and revisions of the Crop Water Allocator and Crop Yield Predictor models   These models are useful and user-friendly irrigation resource management planning tools. Impact of the products can be maximized by incorporating user feedback, expanding the regional applicability, and supporting adoption through promotion, training and technical support.   

Training, user feedback, testing, economic impact, and revisions of the Crop Water Allocator and Crop Yield Predictor models.   Irrigators, Extension agents and specialist, water conservation professionals, and crop consultants found that the Crop Water Allocator (CWA) and the Crop yield Predictor (CYP) are useful in management decisions for limited irrigation.  

Developing Future Water Conservation Researchers   Teacher workshops on water management can make a positive change in teacher attitudes toward the content, their confidence in being able to teach the content, and their intentions to integrate the content into their local curriculum. However, these outcomes are not sustainable without follow-up.  

Survey and in-field observation of emerging alternative Ogallala region irrigated crops.   Six non-traditional crops were identified in the southwest area of Kansas for observation including onion, potato, dry bean, switch grass, canola and cotton. Information on crop growth characteristics and field observations on water use was collected and water budgets developed.  

Map Series for the Texas High Plains / Ogallala Aquifer   In Texas, spatial variability in the saturated thickness of the Ogallala Aquifer is largely controlled by the late Tertiary landscape. Consequently, the ancient landscape has had a profound influence on the spatial distribution of center pivot irrigation systems and rates of aquifer depletion  

Mass media resources and youth cirriculum   Stakeholders are satisfied with the public web site developed for the project. Suggestions for improvement in the site have been used to change the site to its current format. In addition, research results have been recreated into 2-page summaries for easier consumption by various stakeholders.
