24 Water (manure) Control Structure Future research focus: More work with dairy manure Work with radishes in late summer Dragline on preemergent corn and preemergent wheat Fall manure work (maybe N stabilizers) Crop Enhancer for liquid manure application corn and wheat

25 Could expand the window for applying manure to growing corn Manure plots on the web Ohio State University Extension Agronomic Crops Network p On-Farm Research 2008 & 2009 Eventually 2010
