    (University of Minnesota, Water Resources Research Center, 1987-06) Brown, Dwight A.; Gersmehl, Carol A.; Drake, Janet; Skaggs, Richard H.
    The purpose of this report is to define how variations in moisture affect state-wide crop production. To accomplish this goal we controlled geographic variations in the response of crops to changing technology, and regional differences in the severity and timing of wet and dry periods. The regional differences from local norms or unexpected values. Technology changes are controlled by subtracting the general trend in yield from the actual yield technology.
