Corn sulfur deficiencies this year?
I was at a soil fertility meeting a couple weeks ago here in Des Moines. Dave Franzen, a soil fertility specialist at North Dakota State, talked about sulfur deficiencies. He noted that quite a few S deficiencies surfaced in ND this year, and Iowa has also exhibited some. But it's been pretty much sporadic in the rest of the Corn Belt.
Did you notice any S deficiencies this year in your corn? It used to be really rare, only occuring on sandy soils. But combined with higher yields, more residue, etc., there's also less S in the atmosphere than there used to be. So anti-pollution laws work!
