Research
I have a broad-based research and extension program in the area of applied soil fertility. Major nutrients of focus include nitrogen, phosphorus and chloride in dryland cereal and grass seed cropping systems in eastern Washington. I also develop fertilizer recommendations and management guides for dryland and certain irrigated crops. An emerging area of basic research is fertilizer-induced soil acidification and its impacts on crop performance and phosphorus chemistry in the inland Pacific Northwest. Read more.

Teaching
I occasionally  teach Soils 201, Soil: A Living System.
