Spafford, R.R. (1919) Farm types in Nebraska, as determined by climatic, soil, and economic factors (Research Bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No. 15)
This bulletin treats chiefly of Nebraska agricultural areas as determined by climatic, soil, and economic factors. Most of the subject matter centers about the kind of farm crops grown and their yields. Cultural practices applied to crops are only incidentally considered. Most of the data used are from the Thirteenth Census of the United States and cover the crop year 1909. The small amount of data not derived from this source comes largely from field studies in this State and is used merely to support certain methods of treating census data.
