<br />this project that we are working on now. The Soil Conservation <br />determined that the optimum furrow amount of this project was six <br />gallons per minute in each furrow. So we had 60 sets there, and this <br />amounts to 360 gallons a minute which was set on the little flume there. <br />On the recorder, we set this to r~n 360 gallons a minute. Here is one <br />set just starting to operate there. <br /> <br />One of the things that we finally had to do was to go back in there <br />to adjust these ports SO that each one of them would put out the exact <br />amount. <br /> <br />This is the farmer out there adjusting the output. It is going to <br />take a lot of tedious, time-consuming work to measure these flows in <br />the furrow; but we feel that this is the way to get going to get <br />optimum, level, uniform irrigation through~ut the -field. . <br /> <br />Here is the irrigation in progress, and each one of those things have <br />been set to give us six gallons per minute in the furrow. <br /> <br />There is the time gate that has been used in this area, and we think <br />it is going to do the job for us. .When this gate goes down, the water <br />goes out that port. <br /> <br />MR. FETCHER: How does that time clock work? <br /> <br />MR. LONGLEY: <br />of hours that. <br />and the water <br /> <br />It is a 24-hou~ time clock. you can <br />you want. When the gate comes down, <br />goes out the port. <br /> <br />set it for any a~ount <br />it stop's the water, <br /> <br />MR. FETCHER: Just trips it and drops the gate? <br /> <br />MR. LONGLEY: Yes, it has a trip. It has a chain that hangs on the gate <br />itself, and it just lets it go. <br /> <br />MR. GORMLEY: It is a mechanical clock, not electric? <br /> <br />MR. LONGLEY: No, it is not electric. It is mechanical. <br /> <br />That is the part I wanted to show you about the measurement on the field <br />and how important-it is to go back and work with the farmer so that we <br />attain the desired results for this irrigation. <br /> <br />NOW, I would like to show you some irrigation practices that we use in <br />the Orchard Mesa area. This pertains to the Orchard Mesa operation up <br />there and what we think needs to take place there. <br /> <br />That was a drip irrigation. This is a spot spitter, Roberts Irrigation <br />spot Spitter. It is somewhat the same as this little emitter that I <br />have here. I will pass it around. This is one we think is going to <br />work very well, because it takes care o~ a lBO-degree span, as I will <br />show you later on. <br /> <br />One of the big problems is weed control. It is really tough.- tOe manage <br />the weeds in this irrigation. <br /> <br />-24- <br /> <br />I <br /> <br />I <br />
