Show Fertilizers can make good soils better in most instances Assuming that the soil is in that it is well drained, and that any undue acidity or alkalinity has been corrected, we are then in a position to .'get full benefit from recomgood tilth, mended applications of chemical fertilizers. For fertilizers serve aiot only as sources of the mineral nutrients and nitrogen required by crop plants, but of those required by the soil microorganisms as well. Nitrogen and phosphorus are especially important constituents of their bodies. Crop residues are rapidly changed into compost when nitrogen is added, assuming that phosphorous and other required food elements are present in ample amounts in the .soil. Use of fertilizers is the starting point with any unproductive soil, whether farm, lawn or garden. Fertilization provides a means of adding organic matter to all soils, improving their physical properties, and partially overcoming drouth effects. For fertilizer means bigger crops, deeper root systems, and larger amounts of crop residues to be made into organic matter. There are millions of acres FLOYD HARMER Branch Mgr. UTAH POULTRY & FARMERS CO-O- for your P of farmed land that are naturally in good physical condition without any effort on the part of man. This is true of many of the sands and sandy loams on the coastal plain that extend from Massachusetts to Texas, including virtually the whole state of Florida, except for the Everglades. Unproductivity of much of this land is due almost entirely to lack of available nutrients or to serious imbalance among them. Under such conditions, except where drainage is a major problem, a given field can be brought to a high state of productivity in one day merely by applying the necessary lime and fertilizer. Home garden survey indicates need for more fertilizer use A survey of 278 home gardens in six Utah counties last season indicates that home gar- deners are not using enough nitrogen fertilizer for best quality and high yields of sweet corn, says Dr. Howard B. Peterson .agronomy department head at Utah State University. Eighty-twper cent of the gardens observed, says Dr. Pet o erson, showed a corn crop with nitrogen deficiencies. Evidence of the nitrogen lack is seen in the light green to yellow color of the leaves, and in ears that are short and not filled with kernals. A proper balance of nitrogen and moisture in the soil is usually the key to high yields of good quality sweet corn, according to Dr. Peterson.. "Nitrogen also hastens the rate and uniformity of maturity, he added. Nitrogen may be applied as manure or by adding commer- - 5 hal nitrogen fertilizer two or three times during the growing season. It is practical to fertilizer commercial spread between the rows during the growing season. This should be donp often enough to keep the plants a dark green color. Dr. Peterson recommends either broadcast or banding with a fertilizer drill a pound nitrate or 1.6 of ammonium pounds of ammonium sulfate for each 200 square feet, three times during the season. Applied fertilizer can be beneficial as late as silking time. Increase livestock forage by fertilizing irrigated pastures Irrigated pastures are one way of increasing forage for livestock and Utah State University scientists have found that the yield of pasture forage continues to increase when phosphate fertilizer is applied in large amounts. In a study conducted during the past two years by C. H. Mickelsen, G. Q. Bateman, L. Perkes and Dr. G. E. Stoddard of the USU dairy industry department, it was shown that fertilizers continued to give increased response in pasture good yields even when applied at rates as high as 800 pounds to the acre. A grass-legum- e mixture consisting of about 70 legumes was fertilized with a 45 per cent available phosphate fertilizer at the rate of 200, 400 and 800 pounds per acre. Green weight of forage per acre as measured by 60 square foot samples, amounted to 58,352, 53,579, and 54,014 pounds for the three treatments, respectively. The 400 pound application yielded 508 pounds more dry basis than the 200 pound application. When 800 pounds was applied per acre, the dry matter yield was increased 1275 pounds over the 400 pound application and 1783 pounds over the 200 pound application, the USU scientists found. The protein and phosphorous were increased from the 200 to the 400 pound level of application, but not from 400 to of the store that 800.
