We will also have new trash screen <br /> <br /> <br />materials that we are working with made from polyurethane as well <br /> <br /> <br />as surge valves and controller, atmometers, probes and other <br /> <br /> <br />equipment to improve irrigation water management," said Barbara <br /> <br /> <br />Barnett, soil conservationist with the Prowers County NRCS. <br /> <br /> <br />The tour will go to the Ed Bates Farm to look at PAM on corn <br /> <br /> <br />and drainage problems. "The field we will be seeing was growing <br /> <br /> <br />crops in 1994 and now I can't even farm it", said Ed Bates. Luis <br /> <br /> <br />Garcia of Chemical and Bioresource Engineering and Tim Gates of <br /> <br /> <br />civil Engineering at Colorado State University will discuss some <br /> <br /> <br />of the work they will be doing in the area concerning drainage <br /> <br /> <br />and salinity. The group will then go to the Paul Frank farm to <br /> <br /> <br />look at drags on a center pivot system. "I feel drags will <br /> <br /> <br />improve the infiltration of the water being applied and will <br /> <br /> <br />reduce the possibility of salt burn from the saline water being <br /> <br /> <br />applied to the alfalfa", Valliant said, <br /> <br /> <br />Availability of phosphate to the plant may be a limiting <br /> <br /> <br />factor in alfalfa production in this area especially with the <br /> <br /> <br />salinity of the water and the application of sulfuric acid <br /> <br /> <br />materials is being demonstrated by Cory Thompson on one of his <br /> <br /> <br />alfalfa and corn fields. Dr. Steven Petrie of the UNOCAL <br /> <br /> <br />Corporation will discuss the use of Phos-Phuric and N-Phuric on <br /> <br /> <br />these fields, <br />
