During the 2010, 2011, and 2013 I estimated N losses in high clay soils based on my ongoing corn N rate project ranging from about 100 pounds per acre in 2010 to nearly 150 pounds per acre in 2011 and 80-100 pounds per acre in 2013. This spring, I established two multi-treatment corn N rate/side-dress N rate studies.
