Page 32—Corn Talk, Lancaster Farming, Saturday, October 10, 1998 NORCROSS, Ga. When the nutrient deficiency symp toms appear in growing crops, we become concerned that yields and profits will suffer. Usually that is a safe assumption, and we know that the deficiency must be corrected and optimize prof its. Most farmers and crop advisers know the important deficiency symptoms in their crops and will be able to iden tify problems once they are visible. • Unfortunately, con siderable yield potential is already lost when visible symptoms appear. Some of the new tools of site-lpecific farming may offer opportunities to better detect and treat hidden hunger in growing crops. All essential plant nutri ents are required in at least a threshold amount throughout the life of the plant in order to support normal growth and development. If any nutrient falls short of its respective critical level at Conference Showcases Future ST. LOUIS, Mo. The corn indus try got a glimpse of its future as hun dreds of experts from around the world shared research and expertise at the Corn Utilization and Technology Conference (CUTC) here. Hosted by the National Corn Growers Association (NCGA) and the Corn Refiners Association (CRA), the CUTC brought together corn growers, corn refiners, and researchers to explore new uses for corn, share tech nological know-how, and familiarize themselves with new or improved equipment, innovative ideas, and tech niques for corn processing. Past conferences have yielded new technologies in amino and organic acid production from corn starch, major cost reductions and improved productivity and quality in corn refining and pro cessing; and the first genetic transfor mation of the com plant. Nearly 600 people attended this year’s CUTC, including foreign trade teams and visi tors from Japan, Korea, Egypt, Mexico, Brazil, Venezuela, Peru, Chile, the Dominican Republic, and Columbia. “As a corn grower, I want to see even greater uses and value for corn,” said Lee Schafer, NCGA Com Board mem ber and a corn grower from Brighton, lowa. “CUTC is not just pie-in-the-sky predictions of our future. It’s the corn industry’s efforts to ensure the tools we need are commercially viable and available.” CRA President Charles F. Conner agreed. “Corn wet milling technologies presented at past conferences added more than $3.5 billion to the value of 1.3 billion bushels of corn last year alone,” Conner said. “Technologies pre sented at this year’s conference promise to deliver even greater effi ciencies, increased production, and new product ideas that will benefit the entire com industry.” The Corn Utilization and Technology Conference merges NCGA’s popular Corn Utilization Conference and CRAte former Technology Conference into a single powerhouse New Tools Detect Hidden Hunger In Crops any time during the growing season, there will likely be a reduction in growth and potential yield. Even if the nutrient supply is replen ished, there may have already been irreversible damage done. The critical levels for each nutrient, and the effect of deficiency, vary with stage of growth. Deficiency symptoms are usually physiological reac tions to the insufficient sup ply of the nutrient. They are expressed as reduced growth, abnormal color, or death of tissue. Sometimes the effect can be overcome with the addition of supplemental fer tilizers, but often it is too late for corrective action when the symptoms appear. Hidden hunger, on the other hand, is less severe and does not produce the visible symptoms. Thus, it is also more difficult to detect. Analysis of plant tissue sam ples or in-field tissue quick tests can help identify these shortages. New electronic Of Nation’s Top Crop meeting of the best minds in the com industry.

Researchers are experiment ing with in-field measure ment of light reflectance with remote-sensing scanners to detect variability that may be due to hidden nutrient defi ciencies. Plotting such measure ments with global positioning system (GPS) tools and log ging the date into a geo graphic identification system (GIS) database permit farm ers and their advisers to ana lyze the spatial variability of the relative measurements and detect areas of the field where unseen nutrient defi ciencies are possible. Then plant analysis can be used to accurately determine whether there is a deficiency developing, so that corrective action can be taken before the problem reaches the point of severely impacting yield. As yield levels continue to increase and management is Storage intensified, the effects of stress factors will likely be more common, and potential for hidden hunger will increase. Farms and their advisers will benefit from Top Gun Conference Planned for Mercer MERCER (Mercer Co.) The Pennsylvania Master Corn Growers and Penn State Extension will be spon soring a conference on key corn production issues for western Pennsylvania corn producers on Dec. 18 here at the Mercer County Cooperative Extension office. The conference will fea ture some key topics specifi cally targeted at improving crop production in the west ern region. The program will feature Tom Murphy from Lycoming County Extension, who will review how produc ers in his area have initiated and benefited from a grain marketing club. The program will also fea ture presentations on how to produce and market quality grain, including the potential for the new high oil specialty corns on the market. The afternoon presenta tions will focus on how to manage machinery more The unique “Inline Drive" design features an internally mount ed gearbox inside of an expanded, bell shaped tube housing Auger flighting is positioned to allow a high volume of unre stricted gram flow around the internal gearbox A new intake design utilizes double flighting and a cupped intake guard to offer a high capacity, complete cleanout operation A specially engineered hopper bolts directly to top of the intake guard, further enhancing the augers capacity H«U|rv IYeUIIDCT 133 Rothsville Station Rd.

These will include a session on how to extend the effective life of your corn planter. Another presentation in the afternoon will address the process of deciding whether to buy new or used equipment and factors that you need to consider. The con ference also will review the potential of custom farming arrangements that have allowed some area producers to invest in newer equipment while providing a valuable service to the dairy industry in the area. The program will start at 8:30 a.m. and continue until 3:30 p.m. Area ag suppliers will be on hand with exhibits. Lunch will be provided on site. Registration for the pro gram is $7.
