With the high application of water much <br /> <br />salt is leached from the soil by deep perculation losses. From the <br />..-----.. <br /> <br />use, of water study approximately 25 per cent of all water applied <br /> <br />was lost through deep perculation. <br /> <br />The field representatives have worked with the 1972 and 1973 par-- <br /> <br />ticipants to increase efficiencies and reduce losses to deep <br /> <br />perculation. <br /> <br />With the purchase of soil retention equipment soil moisture holding <br /> <br />capacities could be accurately determined. This was needed to <br /> <br />, <br />determine what was required to replace the root zone moisture <br /> <br />without wasting water. <br /> <br />The installation of ground water wells are being used to determine <br /> <br />the ground water effects on crop consumptive use. <br /> <br />, <br />Some wells have <br /> <br />been installed in fields adjacent to canals. It has not been <br /> <br />determined yet if the water tables at these locations are caused <br /> <br />by over irrigation or canal seepage. <br /> <br />Approximately six hundred soil samples were collected during the <br /> <br /> <br />non-irrigation season. One-fourth of these have been anal~,ed <br /> <br /> <br />for the per cent salts. <br /> <br />Water quality samples are collected morlthly throughout the year. <br /> <br />These samples are collected at a number of locations along the <br /> <br />canals and where irrigation runoff returns to the river. <br />
