Soybean question

If he plans on harvesting beans then he definitely wouldn't plant something so intrusive as rye grass under his beans. How many years have you hunted this property? My guess is that the beans are RR and he'll come back and spray to kill the unwanted grass.

 

My beans looked just like that this year. I only sprayed roundup prior to tilling under and no pre-emergence herbicide. That plot has been in been for 2 straight years and with all the extra nitrogen and the extremely favorable growing conditions the grasses took off out of control. Honestly I didn't even take any pictures of the plot because I was too embarrassed at how it looked. I sprayed it with roundup a week or so ago, so hopefully that knocked back the competition enough that the beans can get a good canopy.

I'm guessing your farmer has the same issue and will be knocking them back w. herbicide any day now.

 

That grass may have gotten away from him but farmers don't generally allow grass and weeds to get that large before hitting them with herbicide. RR beans can be sprayed from the time they are up...every hour that weeds and grass are actively growing they are cutting yield so by now he's lost probably in excess of 75% of that crops potential.

Food plots don't matter so much because they are mostly for forage and not grain production but even with them...the cleaner the better the tonnage/acre. That's why I asked the hay question, a crop like that works better than straight grass hay and was the only reason I could think of the guy would allow it to get that advanced, willingly.

 

The field directly across the rd, he planted also and the beans have no grass in them. Both fields were corn last year. I do most of my hunting on the side with no grass, so no big deal either way.

 

Well, my guess is brown mid rib, white midrib or conventional sorghum sudan grass. It's what i recommended to many people around the midwest last year to handle the wet/late plantings. Cows milk like crazy on it. Send me a pic and i'd tell you for sure. Perhaps it's resolve HQ

 

This was my first thought as well considering the semi broad leaves of the "grass" but if the farmer doesn't handle cattle it's confusing as to why he'd waste a perfectly good crop field for the season. Maybe he has a use for it the OP doesn't know about though. Would have been better choices for a cover crop so that's pretty much ruled out.

 

I have no idea why he would let grass get away like that. We run 500 acres of corn and soybeans and we keep a close eye on the weeds and when we can spray herbicide.

There are many types of sorghum sudangrasses out on the market. I fielded a call today from the Minnesota USDA asking me about a sorghum. I actually push the heck out of forage beans mixed with a fast growing sorghum. It also can be used for a food and cover mix for deer on ground that can't be planted til late.

There are also some people planting their "prevent planting" acres to mixes with sorghum, this is due to the inexpensive seed and the money they get from their crop insurance.


Note in the above pic, the holes in the leaves. I am seeing a lot of bug pressure in soybean fields. Populations explode in this weather. It is only about $3 an acre to spray your food plots for bugs.
