Mechanisms of Soil Aggregation and Crusting. Applications: Improved strategies for reducing soil erosion, increasing the efficiency of water use by plants, and reducing the need for irrigation.

Physical Behavior of Pollutants in Soils. Applications: Design cost-effective procedures for removing oil and gasoline from contaminated soils.

These research topics address the research priorities listed in, North Central Regional Association Multistate Prioritization Process (September, 1999).

1. Document the link between animal welfare/behavior, care and management and their environment.

2. Develop remediation systems to reduce agricultural, non-agricultural and chemical waste contamination of soil, water and air.

3. Develop methodology to measure and model air, water and soil quality.
