<br />" 'OC0524 <br /> <br />Waters above an EC of 1.50 "may have adverse effects on many crops, Salinity will increase <br />without adequate leaching", This results indicate that with com, a yield reduction of 10 to 25% <br />can be expected when using irrigation water with an EC of 1,7 to 2,5, (See enclosed Table 3,) <br />And-AGAIN- this has been a year of exceptionaUy high river flow and rainfaU, <br /> <br />Milton Rink continues to be pleased with the surge valve and controUer that he is using on alfalfa <br />and com, He was able to reduce the time ofrun on a field of alfalfa and still get the center of the <br />field wetter than with conventional irrigation he has used in the past. He is also pleased with the <br />stainless steel wedge wire screen that was instaUed to reduce trash in gated pipe on a com field, <br />He said that he has not had trouble with the gates stopping up with trash as he had before the <br />trash screen was instaUed, A short waU around the edge of the trash screen will improve the <br />removal of trash from the water, <br /> <br />As soon as harvest season is over, I am to meet with Jimmy Holmes to discuss installing an Oxion <br />Air System on one ofhis center pivot systems, The Oxion Air unit "pumps atmospheric air <br />through its patented Oxion ceUs, where the air is electricaUy ionized and broken down to the free <br />radical form", "Highly ionized air is injected directly into irrigation water through the water line <br />as it flows to the sprinkler for distribution over the field", Oxion has indicated it will furnish the <br />unit for demonstration for the 2000 growing season, <br /> <br />Oxion presently has two units instaUed on the pwnping units at the Dick Evan's farm east of <br />Pueblo that I will also be working with in 2000, <br /> <br />CWCBHPRIO,99 <br />
