The Magruder Plots: 120 years of Continuous Winter Wheat Research

摘要

Over the decades several articles, journal publications, and many insights have been derived from this un-replicated fertility study consisting of six simple treatments. In the summer of 1892 A.C. Magruder, the first professor of agriculture at the newly created Oklahoma Agricultural and Mechanical College, plowed under one acre of Tall Grass Prairie with an interest in producing continuous wheat without the addition of any fertilizer material. This acre would be used to demonstrate the need for fertility management. Over the next 120 years, treatments would be added and adapted.
