Publication: The Ecological Socielty of America, published online Sept. 14, 2011

Abstract: Plant breeding programs primarily focus on improving a crop’s environmental adaptability and biotic stress tolerance in order to increase yield. Crop improvements made since the 1950s – coupled with…

Publication: "Crop & Pasture Science," July 2010

Abstract: Annual cereal, legume and oilseed crops remain staples of the global food supply. Because most annual crops have less extensive, shorter-lived root systems than do perennial species, with a…

Publication: Agriculture, Ecosystems and Environment, (2009), doi:10.1016/j.agee.2009.11.008

Abstract: Soil ecosystem properties and processes which simultaneously maintain native fertility and sustain plant yields are of principal interest in sustainable agriculture. Native prairies in Kansas are relevant in this…
