Missouri Soil Fertility and Fertilizers Research Update 2009 Agronomy Miscellaneous Publ. #10-01 January 2010 Agronomy Department College of Agriculture, Food and Natural Resources University of Missouri Thank You Missouri Fertilizer and Ag Lime Distributors The contributors to this report wish to express their sincere thanks for the willingness of the Missouri Fertilizer and Ag Lime Distributors of the state who provide funding, through their annual permit fees, for the research which is reported in this publication. These research projects would not be possible without this funding source. I want thank Dr. Randy Miles for providing the Sanborn Field Update report which is included in this herein. While Sanborn Field does not receive financial support from the Fertilizer/Ag Lime funds, this information provides some of the grounding base on which agricultural research was first established in Missouri. For anyone not aware, Sanborn Field is on the National Historic registry and is the oldest continuous plot research site, West of the Mississippi River conducting agricultural research. Researchers, being overtly curious people with a penchant to find out why or how to do it better, normally have a list of topics that they want to research. Perhaps you have a topic that is particularly perplexing to you? These people could very well be the one‘s to ask why? If they don‘t know, then perhaps you will have just suggested the next burning question that will become the object of new research. Any questions or ideas? If you do, send them too us at: Fertilizer/Ag Lime Control Service Attn: Joe Slater University of Missouri-Columbia Columbia, MO 65211-8080 or email them to [email protected] or phone 573-882-0007 1 Contributors to Report Blevins, Dale.
