Ilamson Acting Head, I'SU Horticulture Department Rapid growth of high qualrequires a n ity vegetables adequate supply of soil nutrients. Nitrogen and phosphorous are the elements most likely to be deficient in Utah soils. Mixed fertilizers such as or contain 5 per cent of nitrogen and 10 per cent of phosphrous, or 10 per cent of nitrogen, and 20 per cent of phosphorous, respectively. Nutrients may be applied in the form of nitrogen fertilizers, such as ammonium nitrate, ammoni u m sulphate, or phosphate sources such as superphosphate, trebel superphosphate, or mixed fertilizers. practice is to broadcast half the fertilizer before plowing i n the spring and work the other half into the top three inches of soil after plowing. If the garden i s plowed in the fall, fertilizer should be broadcast in the spring and worked into the top few inches of soil. Fertilizer applied in bands two to three inches deep and two to three inches to the side of the seeds or small transplants will be more A good -- h Research chemists have found ways to capture one particular type of smoke and change it into fertilizers and in the process have established a common bond between Vegetable garden needs supply of soil nutrient western soils, farmers and gar deners have found that these nitrogen-ricfertilizers i n crease their yields at low cost. They offer a vanaty o f services tailored to t he in- Utah coal miners and Utah farmers. Smoke from Utah coal is helping to produce three nitrogen fertilizers at a new Nitrogen Plant in this area. First of its kind at a major American steel mill, the plant is located at the U. S. Steels Geneva Works. The fertilizers are derived as are many thousands of other chemical compound s from captured black fumes given off during the coking high-streng- dividual farmers needs. Anhydrous ammonia is stored as a liquid and injected into the soil under pressure as a colorless gas. The gas adheres to clay particles in the soil and as the soil warms up, changes into nitrate nitrogen which can easily be taken by the plants. Prilled ammonium nitrate is particularly effective for crops that require nitrogen in both the ammoniacal and nitrate forms. It increases the protein content of forage crops, with resulting gains in meat The third fertilizer, ammonium sulfate, is advantageous because its acid residual effect offsets the alkaline nature of most western soils. The presence of sulfur in ammonium sulfate can be an advantage on sulfur-defi- c ient soils because it provides increased dark green color in plants of all kinds. th -- , of coal.
