THE BOX ELDER ' NEWS, Brigham City, Utah Tuesday, March 21, 1961 Alfalfa Crops Surface Use of Phosphorous Will Increase Alfalfa Yield Increase Use a number of fertilizer trials where a site is extremely deficient, even on a stand as old as eight to 10 years, a surface application of phosphorous very often will increase the alfalfa yield as much as according to Rex F. Nielsen, assistant professor of agronomy at Utah State University. The residual effects of phosphorous on alfalfa last over several years. A number of trials have been run where a single application of phosphorous on a highly deficient soil has increased yields as much as 100 five years after the initial application. He added that this will not hold on all situations, and he emphasized that if the soil is really deficient, a single application will last a long time. The residual effect is usually proportional to the amount of phosphorous applied, as the larger appli- cations will give a residual effect that will last longer than a smaller application. He continued, We would suggest that before applying phosphorous to alfalfa, that soil be collected and sent to the state soil testing laboratory at Logan where. a good estimate may be made regarding the phosphorous status of the soils. This is particularly valuable in determining those soils which are well supplied with phosphorous. j In Of Fertilizer Alfalfa is grown more widely in the state of Utah than any one Other single irrigated crop. As a result, considerable amount of fertilizer has and is being used. In the early days when land was Virgin, it contained adequate phosphorous or adequate plant nutrients to grow most crops that Were being produced. Some fifty to one hundred years later, it was found that many of these land nutrients have been removed from the soil so that it is now necessary to replace them in order to produce a satisfactory crop. WITH ALFALFA, the needs are primarily those of supplying phosAlfalfa feeds heavily on phorous. phosphorous and needs it in relatively large amounts in order to produce good yields. According to Rex F. Nielson, assistant professor of agronomy at Utah State it has been found University, through a number of trials that the soils of Utah are well supplied with potassium, another element that alfalfa needs in relatively large amounts. "However, he indicated, "it is available in fairly large quantities in most of our irrigation waters. HE WENT ON to say that a symbiotic relationship between organisms on the plant root is capable of taking free nitrogen from the air and fixing it so that additional nitrogen need ot be applied to alfalfa. "We have also run a number of tests in this area, he continued, and to date have never had any evidence that nitrogen is of any value to a crop of alfalfa. This is rather fortunate then, that we only need one commercial fertilizer to be used with alfalfa. We would Suggest that barnyard and poultry manures be used if they are available. However, they may be used more beneficially on other crops that will also use the nitrogen that is present. HE SAID that the problem with Haifa boils down to primarily Supplying the phosphorous fertili-reWith alfalfa, which is a perennial crop, it is better to Utilize phosphate for the fartilizer On a rotation basis; that is, if sug-h- r beets, which require a high amount of phosphorous, are grown, fertilize the sugar beets to main-tain or reach the phosphorous lev-t- ! that would be adequate for production of four or five years of olfalfa. this to be followed without any additional phosphorous on the alfalfa. Nielson went on to say that if Sugar beets are not grown, then it is desirable to apply phosphorout 8t the time the alfalfa is being planted. It can be applied broadcast prior to planting, or it may be applied after the crop is established. About 100 pounds of available F205, phosphorous, applied every two to four years, depending upon the nature of the soil and the productivity of the land, is usually adequate to take care of the needs of alfalfa. "This would mean, Nielson added, "if un application were made at the time of planta subsequent ing, application might be made two or three years later that would carry the altulfa through the normal three to five year rotation.
