There is little question but that weather conditions are an important factor in the extreme variations of crop yields within the Great Plains area. Years of limited rainfall and extreme temperatures invariably result in greatly reduced yields of farm crops. Years of reasonably heavy precipitation well distributed over the year usually result in favorable crops. Weather factors occur in such a variety of combinations that it is extremely difficult definitely to determine the contribution of each factor toward crop production. A number of factors may enter to vary the benefits crops receive from a specified amount of precipitation. Intensity of storm, soil type, conditions of soil, topography, type and amount of vegetation covering all effect the amount of run-off and thus the percentage of precipitation that contributes to crop growth.
