Bio
Jim Ippolito is currently an Associate Professor in the Department of Soil and Crop Sciences (2016– present). He was previously a USDA-Agricultural Research Service Research Soil Scientist (2007-2016), a non-tenure track faculty member in the Department of Soil and Crop Sciences at CSU (2002-2007), and research associate/PhD student in the Department of Soil and Crop Sciences at CSU (1991-2002). He earned his:
PhD degree in Environmental Soil Chemistry/Quality from Colorado State University (2001)
MS degree in Soil Fertility/Chemistry from Colorado State University (1992)
BS degree in Plant Sciences-Agronomy with a minor in Microbiology from the University of Delaware (1989)

Research Interests
Dr Ippolito’s expertise lies in biogeochemical cycling of nitrogen, phosphorus, carbon, and soil trace and heavy metals, leading to a greater understanding of their environmental mobility, fate, and transport. Dr Ippolito’s team utilizes a combination of wet chemistry and synchrotron-based analyses to ascertain how anthropogenic activities either degrade or improve ecosystem health. They utilize this expertise to answer real-world questions in (agro)ecosystems with respect to alterations in soil physical, chemical, and biological attributes, better known today as “soil health”. Specifically, they focus attention on ecosystem management practices and how they improve or degrade soil health in: 1) dryland/irrigated agriculture; 2) grazed perennial pastures and rangelands; 3) and heavy metal contaminated mined lands. When possible, they link alterations in soil health to water quality, plant health, animal health, and ultimately human health.
Dr Ippolito’s current soil health research focuses on:
Biosolids land application effects on soil health, and crop and plant growth/health within agroecosystems and grazed rangelands;
Best management practices to create sustainable, resilient (agro)ecosystems with respect to crop/plant growth, soil health, and edge of field water quality, focused on:
Alterations in irrigation practice (i.e., furrow vs. sprinkler irrigation)
Conventional vs. strip vs. minimum tillage
In-field residue management
Introduction of animals into managed agroecosystems
Organic agroecosystems
Edge of field grassed buffer strips
Highly disturbed mined land locations (in Colorado, Oregon, Missouri, China).
Manure applications to naturally degraded lands for improved soil and plant health
Reductions in irrigation water quantity and the effect on high mountain meadow and pasture ecosystem soil health
Closing the soil health gap within managed (agro)ecosystems via the use of potential benchmark soils
Creating a soil health program, metrics, for the state of Colorado
Correlating soil health management and assessments in the western United States.
Other current research includes:
Assessing biosolids treatment processes on environmental fate and plant uptake of pollutants (e.g., PFAS and PFOA) following long-term biosolids land application
Rethinking phosphorus fertilizer applications for potato production profitability
Improving fertilizer recommendations for fertilizing cool season grasses
Biochar use for reducing soil heavy metal bioavailability and altering redox chemistry
Integrated solution systems development for precision agriculture; and
Big data innovations projects in conjunction with the USDA-ARS and APHIS.
