re: What to plant for ducks

I was wondering how it was classified as an “Ag field” if it was that deep this year.

I would go Chiwapa and Egyptian wheat. It will create somewhat of a “shrub-scrub” (un-harvested does this too) and offer a lot of food. As the water gets higher it will still have seeds for food, cover and invertebrate substrate. This is as long as the currents, other animals and the winds don’t knock it down.
I haven’t been to your place but that batture land typically holds tons of deer and they would probably eat most of your corn. I would totally forget about soybeans unless you are planting them for deer. If you are, I would plant jap & brown top millet Aug-September. I have had pretty good success with planting behind the combine. I was able to irrigate the millet though.

If the hole is surrounded by woods, then rice might be susceptible to blast which limits the kernels from heading out.
