Lethbridge Herald, The (Newspaper) - July 9, 1974, Lethbridge, Alberta Lethbridge Research Station Water loss from sprinkler irrigation By KEN KROGMAN Soil Scientist Water can be applied nore uniformly with sprinkler systems than with surface irrigation. This is particularly true on uneven or on soils with low infiltration rates where excessive runoff is GOOD SERVICE Is AUTOMATIC TRANSMISSION 'LTD. Phoni 327-0910 1520 3rd AVI. S. Guaranteed Servicing Rebuilding and Exchange likely to occur with surface methods. But runoff loss can also occur under sprinklers if water is applied faster than the soil can absorb it. Losses from evaporation and spray-drift from sprinklers are also impor- tant. Under some weather conditions in Southern the evaporation loss from sprinklers may be large. Losses increase as wind and temperature increase or humidity decreases. They also increase as the droplet size is decreased by increasing the operating STORES USE OUR firestone CREDIT PLAN OR.

If water losses are to be sprinkling in hut windy weather should be avoided. if plants are wilting it will be necessary to irrigate the crop and accept the losses due to evaporation. Increasing droplet size by decreasing the pressure in the sprinkler system and increasing the nozzle size should not be attempted as nozzle size and pressure are matched'. Changes in the operating system may lead to inefficient applica- tion of water and may also result in damage to soil structure Evaporation from the sprinkler system cools the crop. In some this may improve yield and quality of some crops when the growing season is hot and night temperatures re- main high. In Southern the hot weather period is short and nights are cool. The cooling effect of sprinkling does not im- prove crop performance. Battle Potato Beetles GUTHKDN Spray Concentrate Fast knockdown Long-lasting control Easy to use.
