Commercial Fertilizer Basis for Production Minor becomes nsjcr whet easily corrected by proper ncientisu discuss latest fadings In the vital roles minor Hemruts play in so l fertility and crop production. New evidence that these plant nutrients are as important to plants as vitamins are to human development makes the term minor a misnomer," says Dr. Roy C. Lfpps. chief western agronomist for U S. Steel. "We dont think of them as minor anymore," he stresses, because our newest studies of western soils prove that small amounts of these plant foods make major deferences in profitable crop production." CAREFUL SOIL research po nts out while such elements as rinc, copper, Iron, molybdenum, and manganese are used by plants in small amounts, an absence of these micronutrients can have a devastating effect on plant growth. According to Dr. Lipps, these new studies underscore again and again the importance of soil testing programs. While general fertilizer 3 only through a scientific test can an individual farmer know exactly what his farm soil contains, its strengths, its deficiencies and specific needs, he re- ports. Once tested, the soil can be which successful farmers say fertilized prescription" fanners say takes the guess work out of farming and greatly increases their profit potential. This way particular needs can be met on a crop by crop, field by field basis. which iMMatr by successful LATEST RESEARCH, points out these significant facts about western soils: Most soils in the Intermountain area are deficient In the key essential constituent of plant material - nitrogen fertiliof Krogesi-izers such as ammonium sulfate, anhydrous ammonia and ammonium nitrate. AH of the 11 western state contain areas of zinc and iron deficiency. Other elements like and copper boron, magnesium arc also reported in Insufficient supply, however. Iron and zinc d d f cicncies seem to be the most critical from a crop production standpoint. CORRECTION OF zinc deficiencies created dramatic responses in fruit trees, corn and beans plus a significant quality response in potatoes with more No. 1 potatoes produced. Iron deficiencies are most often found in alkaline soils. Soils with high phosphate level accentuate zinc problems where zinc is it insufficient supply. LACK OF molybdenum affects alfalfa and pea production. Crops sensitive to lack of iron include: citrus and fruit trees, sugar beets, potatoes, sorghum, miio, beans and the cereal crops, wheat, barley, oats and rye. Crops sensitive to low level of zinc include: corn, field beans, potatoes, tomatoes, onions, barley, red clover, alfalfa, sugar beets, oats, asparagus, mustard and broccoli. BOTH ZINC and iron can be made more available by using maacidic soil conditioning terials or acid forming fertilizers. Principal among these are ammonium sulfate, ammonium polysulfide and soil sulfur. In summarizing the newest data. Dr. Lipps said: "Re search information points to the fact that many western soils are borderline in their capacity to supply micronutrients for For maximum production. tunately the fertilizer Industry, now has materials and the pre- - Ttidaj.
