Recent attention to the increasing environmental and monetary costs of mining dwindling phosphorus (P) reserves have lead to renewed efforts to design agricultural systems that use P more efficiently. The objective of these experiments was to evaluate the effects of cropping systems, plant genetics and soil microbiology on P use efficiency in crops. Field trials were conducted in five locations across Washington State over 2009 and 2010 to test the responsiveness of five spring wheat (
