Mine are all perennial. I don't even look in the establishment year. It's spendy.
After that, maybe $55/ac. I keep changing mine up, so take that for what it's worth. I'm bumping all my winter cereals and jap millet to late winter/early spring planting, so fall will only see a little flax, more jap millet, and maybe a top off rate of chicory and plantain.
