Excerpt from Water Input Used for Field Crops at the United States Scotts Bluff (Nebr.) Field Station, 1941-44
The tabulated data show a wide range in crop yields, believed to be due chiefly to differences in the soil fertility, resulting from differences in crop sequences and fertilizer applications. In conducting these rotation experiments the aim was to provide the crops with good cultural care, including an ample-supply of water in the root-zone reservoir. The crops were not intentionally irrigated excessively nor were they allowed to suffer for lack of water.
The table shows that in respect to each crop there were great differ enoce in the quantity of irrigation water applied. These differences were not predetermined, nor was the time of irrigation decided in advance. Each plot was irrigated when the condition of the soil or of the crop indicated that it should be, and the quantity applied was determined in the light of long practice and experience. It is possible that in some cases more water might well have been applied and also that in some cases more was applied than could be held in the root zone reservoir. In the latter case there would be, of course, some loss by deep percolation. The detailed data do not indicate that the crop yields were limited through lack of irrigation water.
