Rajun, hope you're ok. That's some rough weather that passed through.

I planted 2" deep. That's always worked well when I've been able to adequately hill the stalks. I used to just fertilize with 10-10-10 pre-plant and then like a neighbor used to do which is at knee high and at the first sign of a tassel.

Two years ago I did a lot of reading and switched up a bit. Kept the 10-10-10 pre-plant and then the first side dressing was at the 5 leaf stage with 2 oz ammonium sulfate per 18' row (I had read that corn likes a tad of sulphur) and added a drizzle of 5-10-15.

Then when the first tassels started pushing I side dressed with 15-0-15 with a drizzle of superphosphate. It was the first year I didn't see any sign of that maroon color low on the stalks indicating some kind of nutrient problem. And the corn did great.

This year I've switched from amm sulfate to nitrate. The nitrate was a lot less expensive.

This is a great pdf from N. Dakota Extension I found two years ago. It explains in detail every single leaf stage with photos too. I learned a lot from this.
