Ah, now I understand.

Down here a freeze is generally not the problem for double-crops; lack of rain and/or droughty, eroded, sloping soil usually is.

We usually have a killing frost by mid October but may not have enough hard ones until October is nearly over--depends on the year. My bigger concern with your timing down here, is that November can sometimes turn rainy--lots of cool, damp, drizzly days where nothing dries. The later we go, the fewer acres we can harvest in a day (even sunny days frost often keeps us out until nearly noon).

You don't have cockleburs there? Or sunflowers? Even with conventional or unknown-origin bean seed I think we'd be looking at an application of something like Basagran for burs.

But the entire program you describe intrigues me, and might be worth trying here on a few acres.

This year i'm going to plant oats + berseem clover--my first try with berseem, though I know others who've grown it here. The berseem is sensitive to frosting, so needs to be planted 3+ weeks after the oats (frost seeding is very risky). After overseeding I'm thinking of running a rotary hoe over it to improve seed-to-soil contact for a better stand. I can at least try the hoe a bit to see its effect on the seedling oats before I'm committed to that as a plan. Or maybe, run over it with a culti-mulcher with the teeth retracted, just to move a little soil. A lot will depend on whether the soil is dry enough or not.

Those who've grown it say it should give me at least two good cuttings most years. The first would be "stubble hay"--oat straw + berseem. Some of the best hay I've fed years ago was wheat + red clover stubble hay. Even 500# calves loved it & consumed a lot. And of course oat straw is more palatable.

One of my bigger concerns is how much N to use. I'm hoping the berseem is aggressive enough to survive a fair amount of N application over the top...while holding back a bit on the early spring application to avoid too much competition for the berseem.

Like every year, it will be interesting even if it's a train wreck.
