Bio

Jim Ippolito is an Associate Professor in the Department of Soil and Crop Sciences.  He earned a PhD degree in Environmental Soil Chemistry/Quality from Colorado State University in 2001, an MS degree in Soil Fertility/Chemistry from Colorado State University in 1992, and a BS degree in Plant Sciences with a focus on Agronomy from the University of Delaware in 1989.  Jim’s professional activities and research interests include soil fertility, chemistry, and environmental soil quality in a number of ecosystems such as production agriculture, rangelands, forests, burned areas, and mine lands.  Among other capacities, Jim also serves the American Society of Agronomy, Soil Science Society of America, the Western Nutrient Management and Water Quality Workgroup(WERA-103), the Beneficial Reuse of Residuals and Reclaimed Water Workgroup (W3170), and the International Conference on the Biogeochemistry of Trace Elements Committee.  He has (co)authored over 180 peer and non-peer reviewed articles.

Research Interests

My expertise lies in biogeochemical cycling of nitrogen, phosphorus, and carbon, and soil trace and heavy metal mobility, fate, and transformations.  I utilize this expertise with respect to the utilization of materials that otherwise would go to waste, such as biochar, biosolids, and drinking water treatment residuals, for beneficial reuse in (non) irrigated agroecosystems, disturbed rangelands, mined lands, and forest fire burned areas.

My current research specifically focuses on:

  • Biochar effects on soil chemistry, fertility, microbiology, water, crop growth, and environmental quality within (agro)ecosystems;
  • Biochar sorption of heavy metals: quantification and sorption mechanisms in extremely disturbed ecosystems;
  • The effect of dairy lagoon waste effluent on soil copper chemistry and crop growth, and means of recovering copper effected soils as well as copper from lagoon effluent;
  • Changes in soil nitrogen, phosphorus, and carbon chemistry within irrigated and non-irrigated (agro)ecosystems;
  • Soil and irrigation water phosphorus sorption by alum-based water treatment residuals, alum, and polyaluminum chloride.
