This two year study is a follow-up to a study started in 1999, looking at phosphorus applications at planting on wheat and barley. Treatments applied were 0, 100, 200 and 400 pounds of 16-20-0 planted through the grain drill with the seed. Phosphorus applied at planting improved yields in most replicates, but because of the cost of the fertilizer, the higher yields were not always the most economically profitable.
