Field trials and laboratory tests were conducted over a period of three years in order to determine the effect of treble superphosphate on small grain yields in southeastern Nebraska. Farmers in this area cooperated in the testing program by assisting in the placement of the plots on their farms. Emphasis was placed on the completion of as many well distributed tests as possible with a minimum of disruption to the cooperator’s own farming operations. The fertilizer was drilled with a combination grain and fertilizer drill or by mixing it with the seed and sowing the mixture with ordinary grain drills.
