<br /> <br />24 <br /> <br />FARM IRRIGATION IN 1981 <br /> <br />~ <br />~ Huntington Farm <br />~ <br />~ The irrigation applied to the Huntington Farm in 1981 was 570.3 <br /> <br />acre feet. The area irrigated was l53 acres. Thus 3.73 ft (44.7 inches) <br /> <br />of water per acre was applied. A study of the general climate of the <br /> <br />area indicated maximum evapotranspiration of about 30 inches/year. The <br /> <br />irrigation water applied on the plots, where irrigation was applied to <br /> <br />match evapotranspiration (irrigation level 5), was 27.6 inches from June <br /> <br />10 through September 2. This agrees quite closely to the 30 inches for <br /> <br />the entire year. Since it was desired to irrigate with about 10% leaching, <br /> <br />it soon became apparent that the water supplied to the evaporation pond <br /> <br />was too much for the acreage available. Apparently more water was put <br /> <br />into the pond than was originally expected, especially during time of <br /> <br />breakdown and repair. Thus, more land will be needed to handle this extra <br /> <br />water. Possibilities are being considered to enlarge the pond and enlarge <br /> <br />the acreage irrigated to about 300 acres total. <br /> <br />Hunter Farm <br /> <br />The irrigation applied to the Hunter Farm in 1981 was 410 acre feet <br /> <br />to 245 acres. This amounts to 1.67 feet (20.1 inches)/acre. Thus there <br /> <br />was, on the average, no leaching in 1981. The climatic study for this <br /> <br />area indicated that yearly evapotranspiration was about 33 inches/year. <br /> <br />Since two more units are in process of being built at this site, more land <br /> <br />will be added for irrigation in the future. <br /> <br />
