In the bad drought year of ‘12, we had a fall strip tilled COC field make 117 bu. acre. Field adjacent was also COC, but previous fall was hit with a dominator and then with a sunflower finisher that spring. Very little residue left on top and pretty black. They ended up selling it to a local cattle guy for silage. Crop insurance adjuster appraised it at 17 bu. acre. That year, soil temps got incredibly warm if there was no residue left to reflect the suns hot rays. My heavy mat of residue between the rows greatly helped keep the ground beneath much cooler. Was a real eye opener for me. I know you’re asking about now, but those were my iowa experiences in the worst drought I’d ever endured, and I’ve seen a few.
