Centre county Pennsylvania, USA | Interesting numbers Jon, thanks. Your dismal numbers for "Drought of 2011" pretty much agree with climate yield model for the US cornbelt. That model uses only summer climate temperature, not summer climate precipitation, to achieve very high correlation (Rsquaded = 0.91) with USDA reported corn yield. That says that high temperature, not drought (precipitation) explains corn yield in the corn belt. Your 2011 irrigated corn yield numbers ("Whole pivots made 65 bu down from 220 the year before") agree with the climate yield model. It says irrigation will not reasonably compensate for high summer climate heat. |
Sea Change... Wasn't this suppose to be the 1980's again?
