Land Price Crest?

This chart is open to that interpretation (from Big Picture Agriculture):

 With already falling grain prices, the bearish impact of the ethanol mandate reduction, lack of interest from Wall Street, higher interest rates due to eventual Fed tapering and increasing fear of  deflation, I think land prices will face severe headwinds going forward.  I would call a secular agricultural land price peak for the time frame between harvest 2012 and harvest 2013.
