Commonwealth National Bank «* N Usage don’t know. With so little knowledge of how the soybean plant ob tains nitrogen, and in view of the soybean’s need for such large amounts of the element, researchers fear, that nitrogen could some day become a limiting factor in producing higher yields. To prevent this from happening, the American Soybean Association (ASA) Research Foundation is funding a project at the University of Missouri to learn more about how the soybean plant obtains and metabolizes nitrogen. When the project began, it was believed that the soybean plant converted nitrogen into amino acids, the building blocks of protein, in only two ways: -Nitrates from the soil are transported to the leaves, where they are converted, or reduced, to Unlock amino acids. This process occurs largely in the early part of the growing season. -- A strain of bacteria called rhizobia form nodules on the roots of the soybean plant and draw nitrogen from the air for the plant to use. This occurs in the latter part of the season. However, researchers at the University of Missouri soon made an important discovery: The nodules not only fix atmospheric nitrogen, but also reduce a significant amount of nitrates from the soil. In fact, early results in dicate that nodules may be more important for the reduction of soil nitrates than for the fixation of at mospheric nitrogen. This new information changes the whole picture of soybean metabolism research and gives all scientists studying the Lancaster Farming. Saturday, Dec. 28,1974—17 soybean a better and more complete basis for their work. From experiments last summer, the Univcrsityof Missouri team obtained the general pattern of nitrate reduction and fixation over the season. This winter, the scientists are running growth chamber and greenhouse experiments in which they completely control the environment, enabling them to account for all of the nitrogen metabolized by soybeans. They are using a stable isotope of nitrogen to trace the pathway of soil nitrates and atmosphjeric nitrogen through the plant in order to calculate more precisely the relative importance of reduction and fixation in the nodules. Information gained will help answer the soybean nitrogen mystery and assure higher yields in the future.

Poultry exhibited at the Farm Show are exposed to many diseases not common to their flock of origin. These show birds should be kept separate from the main flock after the show for at least 30 days. Most infections contracted by poultry at shows will break before the 30-day isolation period is up. If there are no breaks, then it is probably safe to place these birds back with the flock. In the event that disease strikes, they should not be put back with the flock. Recovered birds remain carriers and shedders of certain diseases. Many disease breaks can be averted by establishing a sound vaccination program. However, there is no reliable vaccine available for some of the bacterial diseases for which the recovered birds remain carriers. Examples of these are coryza and fowl cholera. Be on guard for coccidiosis, too, because the show birds may have no immunity to certain species. Look for a coccidiosis break 1 to 3 weeks after bringing the birds home.
