“Monitoring soil salinity and assessing adequacy of leaching and drainage”
My current areas of focus include the following: Nutrient requirements for Arizona crops, especially pecans, turf grass, and vegetables; nutrient requirements and management in contaminated soils, concentrating on effects of nitrogen on soil water potential and microbial petroleum biodegradation; irrigation water and soil salinity management in agricultural soils; and application of waste materials to soils, studying rates of degradation of soil-applied animal manures and environmental impacts of on-site human waste disposal systems. I received my B.S. (1976) and M.S. (1980) in Soil Science from the University of Wisconsin – Madison, and Ph.D. (1985) in Agronomy from the University of Georgia.
