The 10-day is showing a potential frost event around May 8 for northern Iowa — 28°F at Mason City. If we plant corn early like April 25 and that frost hits, we could have emergence issues. ISU says corn can handle a light frost before V2 but I'm nervous. Tempted to push first planting date back to May 1 to be safe. What's your plan?
Same forecast here. I'm watching the 500mb charts and it looks like that ridge building after May 10 will push warm air north fast. I'll probably start April 28 and accept the risk — the yield drag from late planting in our area is about 0.5 bu/day after May 5.
