It is the purpose of this study to further characterize the major soils of the different sections of the state which are devoted to wheat production, and then analyze fertilizer practices and results in recent and past years in relation to the soil properties determined. The data presented are summarized for the four sections of the state designated as southeastern, east south central, west south central and western. These subdivisions have been made because of variations in soils, climate and customary soil management practices; thus each section is reasonably uniform as to these factors.

The results of the recorded fertilizer studies with winter wheat in Nebraska are presented for the entire period 1920 to 1949. The major zonal soils upon which wheat is produced are recognized as Sharpsburg, Crete, Hastings, Holdrege, Keith, Sherman and Rosebud soil series.
