The majority of my work involves manure management, pasture productivity and nutrient cycling. Much of the work has looked at nutrient cycling in pasture systems, developing techniques to document nutrient utilization and variety trails to determine varieties with improved performance. Additional work has involved cooper and phosphorus management on dairies and fiber digestibility in cool season grasses.
