Investigating the use of satellite, aerial, and ground-based remotely sensed data to improve agricultural efficiency and protect natural resources.

Studying the impacts of spatial variability on our ability to measure and understand properties which impact crop development, runoff, soil erosion, and water quality.

Using crop development models to understand the effects of spatially variable properties, and to explore linkages between agricultural production and environmental impacts.

Studying ways in which site-specific farming can optimize production and efficiency while minimizing negative effects on soil and water quality.

Using hydrologic models, in combination with field measurements, to understand the hydrological behavior of water management systems, and to study the influence of alternative management scenarios.
