Show SOIL MANAGEMENT STUDIES ARE BEING UNDERTAKEN A sound system of soil managj-ment managj-ment must satisfy two fundamental conditions. It must insure: (1) a high yield of crops if farming is to be worth while, and (2) the least possible possi-ble loss of plant food from the soil to obviate the dangers of depleted and worn out soil, acording to Dr. D. S. Jennings, who is charge of soil surveys of the Utah Agricultural Experiment Ex-periment Station. To secure a high yield a number of 'cvois must be considered. Fertilizers Ferti-lizers can be applied to the soil to insure in-sure plenty of plant food. Barnyard I manure is the best fertiliers we have, but if it cannot be secured commer- cial fertilizers can be used provided it is known just what elements of plant food are lacking in the soil. It is poor management to buy expensive fertilizers that are made up of elements ele-ments that the soil already contains in abundance. Irrigation, drainage, j rotation, , and cultivation are other big factors in the producing of high : yields. ; It has been found that one kind of treatment of soils in a given locality may not give results when applied to soils in another locality. Even on a single farm several classes of soil may be found. Each class of soil requires a different kind of treatment treat-ment to obtain the best results. ' The Experiment Station in cooperation cooper-ation with the Bureau of Soils of the U. S. Department of Agriculture is attempting to classify soils. It has been found that classes of soils in an area are often duplicated in other areas so a number of definite classes can be established. When all these classifications have been made then a treatment for each class will be worked out. ' I |
