Book excerpt: Excerpt from The Relations Between Crop Yields and Precipitation in the Great Plains Area, Vol. 1: Crop Rotations and Tillage Methods The cost of the maintenance of a practical summer fallow is one-half the acre cost of producing a crop of wheat, oats, Or corn. These relative values are therefore used in the following comparisons of crop rotations. As an example of one method of studying the theory and practice of crop rotation and tillage371 methods based upon these investigations covering 228 crop years, the continuous-cropping series, the aitel nate-fallow series, and rotations 1 to 9, inclusive, have been selected. They include 33 crops and 6 fallows each year at each of 16 field stations for an average period of 14% years, a total of plots. The rotations are simple 3-year rotations, and they are so arranged as to facilitate the comparison of different crop sequences and tillage methods.
