Fig. 2. Cumulative soil water depletion by Year 1 crops measured in 0.3-m-depth increments by comparing soil water status with the chem fallow control at four sites in Montana. Bars marked with the same letter do not differ (P < 0.10). Denton is not included because the soil depth was only 0.6 m and soil water differences among crops did not occur at that site due to the shallow soil.
