An area of approximately 40 <br /> <br />acres will be leased for the study. It is contempl~ted <br /> <br /> <br />that the area will be near the Government Highline Canal <br /> <br />from which the water supply will be obtained. <br /> <br />This intensive study area will be divided into about <br /> <br />60 plots each 100 feet square (10,000 sq. ft.). Both <br /> <br />timing and amount of water application will be varied. A <br />pump, power unit, and other pumping plant components will <br />be selected so that they are capable of supplying water at <br />a constant pressure for the variety of discharges which are <br />necessary to irrigate the various plots properly and at the <br /> <br />, time needed. <br /> <br />The amount and chemical quality of irrigation water <br /> <br /> <br />will be monitored to determine the system input. Rainfall <br /> <br /> <br />and temperature data will also be collected. Solar radiation, <br /> <br />wind, and humidity data will be obtained from the Grand <br /> <br />Junction weather station, which is located only a few miles <br /> <br /> <br />from the intensive study area. <br /> <br /> <br />Drains will' be installed across both the tipper sides of <br /> <br />the plot area. They will be used to intercept any natural <br /> <br />. <br /> <br />discharge water which might otherwise get into the plot area. <br /> <br />This natural drainage water,will be monitored for chemical <br />quality and quantity. <br />
