djm,

My apology for putting up the first chart - have changed to intended log scale.  

It's difficult for me to get too excited about four or seven dollar corn. Both are relatively cheap. It's equally difficult to get excited about rising interest rates. They, too, are nominally low. That, combined with observing many commodities - from metals(not necessarily, but including PMs), to softs, to grains, all making major lows this year.
