Show IDEAS ON FERTILIZER FOR SPRING GRAINS Scientists at Utah State University have Indicated that handling fertilizer requirements of spring grains can be done In several In Uie animal manure was used to supply Uie needed plant With the increased intensity in farming in It Is no longer possible to obtain enough animal manure to take care of these As a it has been necessary to resort to commercial A practice that is followed by farmers to supply which is the principal plant growth clement needed by is to follow alfalfa with small When alfalfa is plowed Uie nitrogen-fixing organism in Uie nodules remain on Uie plant decompose and release nitrogen to Uie new As a when alfalfa has been plowed and spring grain the nitrogen level of that soil Is usually high the first Very often the amount of nitrogen supplied by Uie alfalfa crop is adequate to take care of a good crop of a small residual effect will remain the second year following the plowing out of Where is not used in the rotation or where the grain crop is planted several years beyond the time the alfalfa is plowed then it becomes necessary to apply nitrogen When a nitrogen fertilizer is applied to small usually an increase In yield However since a plant is more it grows more lush and Uie problem of lodging is of grains should be used in order to avoid this The a-mount of nitrogen to be applied to small grains will be influenced in part by the amount of water available and also by the amount of residual nitrogen present in the the range would be something on the order of 50 to pounds of available This can be supplied with pounds of ammonia nitrate or some pounds of ammonia The nutrient requirement for small grains in Utah is i marily limited to that of nitrogen- Nitrogen supplied from commercial fertilizer usually is used up Uie first year It is Residual effects nitrogen are small If they exist at It is sary to plan Uie nitrogen requirements of small grains each year and not rely on a residual effect left over from Uie previous One exception to would be with Uie growing of small grains following a crop of sugar beets in which considerable nitrogen usually remains In Uie A number of trials have been conducted over the past 10 years to determine the requirements of small grains on dry studies have shown that most of our state is lacking in available water or Where precipitation is nitrogen on small grains on Uie dry lands has been relatively Rates for dry land winter wheat will be on Uie order of 40 pounds of available nitrogen per |
