<br />....., <br />00 <br />~ <br /> <br />,- <br />- <br /> <br />demands to be used in developing irrigating plans for the coming season, In addition, crop <br /> <br /> <br />consumptive use requirements for the early part of the season (April) not previously developed <br /> <br />were to be estimated. <br /> <br />Crop water requirements or gross crop consumptive use is the amount of water a plant needs <br /> <br />to grow and attain full yield potential. The gross consumptive use value estimated depends on <br /> <br /> <br />the crop type, location, and month. As part of the Phase 1 Study analyses, gross crop <br /> <br />consumptive use values were estimated using an altitude calibrated Jensen-Haise procedure. <br /> <br />The gross consumptive use values estimated with this procedure for alfalfa, spring grains and <br /> <br /> <br />grass hay jpasture for the months of May to September for the Norwood area are shown in <br /> <br /> <br />Table 1 and for the Redvale area in Table 2. <br /> <br />TABLE 1 <br />ESTIMATED GROSS CROP CONSUMPTIVE USE (INCHES) <br />NORWOOD AREA <br /> <br />QLQQ <br />Alfalfa <br /> <br />Apr <br /> <br />Mav <br />1.32 <br /> <br />Jun <br /> <br />JY! <br />7.31 <br />9.59 <br /> <br />Aug <br />7.30 <br />6.48 <br /> <br />~ <br />4.36 <br /> <br />Oct <br />0.75 <br /> <br />Total <br />29.68 <br /> <br />Spring Grains <br /> <br />Grass Hay j <br />Pasture <br /> <br />1.26 <br />0.37 <br />1.09 <br /> <br />1.62 <br />1.34 <br /> <br />7.38 <br />5.33 <br /> <br />0.0 <br /> <br />0.0 <br />1.01 <br /> <br />23.39 <br />30.31 <br /> <br />7.14 <br /> <br />7.87 <br /> <br />7.38 <br /> <br />4.48 <br /> <br />NOTE: <br />1) <br />2) <br /> <br />May to September data estimated using 1983 altitude calibrated Jensen-Haise procedure as part of <br />Phase 1 Study. <br />April and October data estimated using SCS "Colorado Irrigation Guide" values. <br /> <br />3 <br />
