Some times farmers will plant a soybean field and let the field grow to a certain length of time just to get a nature nitrogen from the plant.
Yes, possible, but I was having trouble thinking of why you’d let a soybean crop get all the way to late August, probably less than a month from normal bean harvest and then not harvest it AND go through the additional trouble of mowing it down while it was still growing and presumably fixing N? It’d seem to me that it’d be funny to just blow the bean yield on the ground rather than combine it off and recoup more of your planting investment, but it could happen.
What else could get planted this late?
Well, the most likely option is nothing. Sorry to be a downer and you don’t say exactly where this is, but assuming it’s MN or WI, then both cover crops and overwinter crops like winter wheat and rye are relatively rare for a variety of reasons. If this is further west or south, other options are more common. Anything could happen, but just don’t want to falsely boost your hopes.
Have you thought about talking to the farmer and seeing what his plans are?
Interesting situation, though. I’ve noticed that it seems with the low grain prices that all kinds of non-traditional crops and methods are being tried now. Edible beans are a hot one, so are hops. Organic grain is another, out by Alexandria last year I saw the weediest wheat field I’ve ever seen and dad commented what a mess, but then it dawned on us that he’d gone organic. Saw a guy on a swather cutting grain in western MN a few years ago as well, almost nobody’s used a swather out there for probably 40 years, but going organic makes you get creative to get the weeds through the combine.
