<br />,: "1Ifo.'" <br /> <br />ljlJ\j~\ <br /> <br />A PAM injection pump was installed on the Paul Frank center pivot system and PAM will be <br />applied through the pivot. The effect ofP AM on water penetration will be observed on the two <br />areas comparing sprinkler application with water application through drag hoses. Yield and <br />quality will also be compared under the two methods of water application. <br /> <br />Two surge valves were installed at the John Allen farm on alfalfa to demonstrate a more effective <br />method of applying irrigation water. The alfalfa is on a very sandy soil with a very high <br />in:fiItration rate and is very difficult to irrigate. Surge irrigation may be combined with PAM to <br />able in increase advance rates if erosion takes place. <br /> <br />Twenty five (25) observation wells were also drilled on the Donnie Hammit furm to do testing for <br />hydraulic conductivity for subsurfuce drainage as well as on the Fletcher, Frank, and Thompson <br />furms. Each of these wells will be used to observe the effect of the different BMPs at the different <br />demonstration sites. <br />
