I doubt you'll see a yield response to copper here on corn or soybeans. Maybe on oats.
I once pumped about 10 lbs/acre copper sulfate through the pivot onto 1/4 circle. That showed up in the tissue tests! But not on the yield monitors.
You can get copper sulfate in prills for blending or you can get sprayable powder. I wouldn't be afraid to put either on top of un-frozen no-till soil, if you've got decent biology and residue cover it will work it's way down.
But I wouldn't expect an economic yield response unless you're already at very high yield levels.
Yes. You are much more likely to make gains focusing more on the basics of nutrition, than by simply adding adding cu |
