Show Several Methods Are Detailed Summit County Bee 7 Fertilizer Edition for Supplying More Nitrogen Scientists at Utah State Uni. vanity hart indicated that hand-lin- g fertiliser requirements of spring trains can 1m dona In several ways. In the past, ani mal manure was used to supply the needed plant nutrients. With the Increased Intensity In farm, tag currently in practice, It is no longer possible to obtain enough snlmal manure to take care of these needs. As a result, It has been necessary to resort to fertlhiera. com-tutrcl- al A practice that la followed by farmers to supply nitrogen, which Is the principal plant growth element needed by grains, It to follow alfalfa wKh small grains. When alfalfa is plowed up, the nitrogen-fixin- g organisms in the nodules remain on the plant roots, decompose end release nitrogen to the new crop. As a result, when alfatfa has been plow ed up, the spring grain planted, the nitrogen level of that son Is usually relatively high the first yeaf. Very often the amount of nitrogen supplied by the aXatfa crop Is adequate to take care of a good crop of grain. Normally, a residual effect will be gotten the second year following the plowing out of alfalfa. However, th'n Is depleted primarily At that time. Where aKaKa Is not used In How many kmk THURSDAY, MARCH 25, 1968 a residual effect left over from the previous years. One excep tion to this would he with the growing of small grains following rotation or where the grain crop a crop of sugar beets in which H planted several years beyond considerable nitrogen usually rethe time the alfalfa Is plowed out, mains in the soil then it becomes necessary to ap A number of trials have been ply nitrogen fertiliser. When a conducted over the 10 years nitrogen fertiliser Is applied to to determine the past re fertility small grains, usually an increase In yield results. However, since a plant is more vigorous, it grows more lush and the problem of lodging la acute. Stiff ttra wed varieties of grains should be used In order to avoid this problem. The amount of nit rogen to be applied to small trains will be Influenced In part by the amount of water available and tlao by the amount of red. dual nitrogen present In the soil. Normally, the range would be something on the order of 50 to 100 pounds of available N breaker. This can be supplied with 100 pounds of ammonia nitrate or some 350 pounds of ammonia aul. phate. The nutrient acquirement for small grains In Utah In prl marUy limited to that of nitrogen. -- Nitrogen supplied wKh commercial fertiliser usually Is used up the Urst year It Is applied. Residual effects . with nitrogen are relatively small ft they exist at alL It Is necessary to plan the nitrogen requirements of small grains each year, and not rely on quirements of small grains on dry lands. These studies have shown that most of our state Is lacking In available water oreolortation. Where precipitation is favorable, nitrogen application on small grains on the dry lands has been relatively successful. Rates for dry land winter wheat will bo on the order of 40 pounds per acre. 0 i.jt . - do you raise to the acre?
