The end of agriculture subsidies?

Obama:

In this budget, we will [...] end direct payments to large agribusinesses that don't need them.

I don't know what he means by "direct" and "large" (and "need") -- there is certainly ample room for interpretive fudging -- but I hope this is referring to the tens of billions of dollars that the US doles out each year in agricultural subsidies, much of which goes to farmers who don't actually farm. (For some of the many, many reasons why these subsidies are a terrible idea, see here.) This seems like one of those things about which there is economic consensus.
