Show Utah State Fair Offers Soil Saving Exhibits Profitable control of dam aging ag-ing soil and water losses comprise com-prise exhibits occupying 135 feet of frontage, secured from the U. S. Department of Agriculture for the Utah State Fair, Salt Lake City, September 15 to 23. J. A. Theobald is secretary-manager. Loss of productive soil, as pointed out in the exhibit, concerns con-cerns everyone. A model of a magnified section of topsoil most injured by erosion shows that this layer contains in greatest abundance the elements needed by plants to make a good growth. Eroded land, deficient in minerals and other elements, may produce deficient crops, which, in turn, affect the livestock live-stock which live on the crops, and in some cases the people who eat food raised on that land. First step is to "know your land' and its weak spots, which is covered in the exhibit with soundcolor. With such knowledge knowl-edge as a start, conservation measures are applied to promote better farming methods which save time, labor, machinery, fuel and fertilizers. Basic facts and methods of land and water conservation are set forth by enlarged en-larged photographs and attractive attrac-tive color displays. Conservation problems often require community or area-wide action for solution. The Soil Conservation Districts provides an organization for such action. Despite all such efforts, only 11 per cent of the soil subject to' erosion is now protected. Also included in this group is a watershed exhibit. Models and animated features in this exhibit show that a large proportion pro-portion of the water available comes from mountain watershed, water-shed, which can be protected by careful grazing and forest cutting, cut-ting, thus insuring a continuing supply of clear water. Visitors will be able to secure copies of available bulletins of the Department and get suggestions sugges-tions as to further sources. |
