Kate Reardon

Educational Background:

I received a Ph.D. in microbiology in 2005 from Montana State University in Bozeman and a Bachelor of Science in 2001 from Idaho State University in Pocatello.

Research Program: Soil Microbiology

Current Research Projects:

  • The focus of the microbiology program is to develop new knowledge about microbial benefits derived from diversified crop rotations. The primary objective of the current research plan is to determine whether wheat-oilseed rotations compared to traditional winter wheat-summer fallow provide belowground benefits from changes in the soil microbiology such as increased nitrogen availability, improved soil structure, and reduced disease. DNA- and culture-based methods are being employed to (i) characterize and compare changes in the microbial diversity, composition and function in response to crop rotation, (ii) identify key changes in fungal and bacterial populations with relation to soil structure, and (iii) determine whether Brassica oilseed crops inhibit or “biofumigate” soil communities near the root (or rhizosphere).

Additional Research Projects:

  • USDA-NIFA, AFRI Competitive Grants Program Climate Change Research, 2011-2015. Project Title: Site-specific climate-friendly farming. In collaboration with Washington State University-Pullman (David Brown, P.I.)
