I have heard several different numbers for pounds per acre of soy beans. These are going in notill into sod with a four row planter. The County employee I spoke with(owner of the drill) said 40lbs per acre and a half. Another sorce said 50lbs per acre and yet another said 70lbs per acre.
The last word I received said if I over seeded the yeild could be cut severly.
Let me know what you know. Thanks

The links should help you out but I have to say that I have never seen a problem with "over planting"
For one thing the deer are likely to hammer it pretty hard anyway. Yield from a farmers perspective will maximize at a certain population rate and fertility levels...but it takes a heckuva lot to reduce yield.
As the links should explain...there will be -X- number of seeds per # and based on 50# you can figure from there. Many seed companies are selling by seed count...normally at 80,000 seeds per bag. So you have to check with the seed dealer also. You can easily go as high as 200,000 seeds per acre if drilled or broadcast but that's pretty high for a 4 row. I have planted mine with a 4 row no-till also but I went over it twice so it was closer to 15" rows.
If your using RR beans you need the canopy that prevents further weed growth or you may need to spray several times. 15" rows will give you decent canopy but even then it's iffy.
If the field is hidden and it's a small acreage...plant on the heavy side because the deer and turkeys will both eat much of it before it ever get's more then a few inches high
