Résumé
Rainfed agricultural systems in the Southern Great Plains (SGP) are plagued by persistently low yields and water use, due to the combined effect of droughts, monoculture, and soil health degradation. This environment amplifies yield variability posing a risk to the food supply and producer’s income. Novel cropland observation nodes (CRONOS) will deliver real-time soil moisture information to producers and extension agents. Data from field experiments will construct detailed water and nutrient budgets of existing and improved cropping systems. Integrated modeling, remote sensing, and ground-based monitoring will simulate innovative crop-livestock production systems and generate effective decision support tools. On-farm sites will evaluate production practices for successful adoption of intensified/diversified systems for enhanced water and N use. This project will provide training to undergraduate and graduate students, who will gain hands-on experience regarding sustainability of rainfed agricultural systems.

Objectifs
Our long-term goal is to sustainably increase productivity of rainfed agricultural systems in the SGP by increasing water and nitrogen (N) use efficiencies and reducing yield losses due to environmental stresses while enhancing soil health. Toward this goal, we have assembled an interdisciplinary team with research, teaching and extension expertise in agriculture, economics, and sociology. The overall objective of the project is to develop and extend new information and technologies that enhance long-term strategic management and in-season tactical management of SGP cropping systems and to create new opportunities that educate and equip producers and students to utilize these best management practices. The project includes four integrated research, extension, and education objectives : 1) Develop effective strategic management for diversification and intensification of SGP cropping systems, 2) Develop effective tactical management for improved mid-season input decisions, 3) Provide integrated extension to empower stakeholders to understand and use the resulting information and technologies, and 4) Create educational opportunities to recruit and train the next generation of agricultural systems managers and researchers.
