if you counted every soybean on the ground in a square ft area , you can calculate an average loss per acre . Has anyone a table that refglects such a formula ?..thanx jim

It"s a bit more complicated than that. Gleaner op manuals, or the little shirt pocket notebook they had years ago, gave a step-by-step procedure to go through, depending on the combine and head. First of all you need to calculate loss in front of the head, (which you cannot save since they already popped out of the pods, usually from being too dry, or swelling after a rain) then between the head and the rear of the machine- that gives you actual header loss...then behind the center of the machine for separator loss, and losses to the side, through the chopper/spreader. Add each of them together to figure total yield loss. Beans lost per square foot behind the separator means nothing without header width.

figuring field loses is explained in your combine operating manual..... try reading it

I'm not a farmer, but in reading this, it seems like your saying there are a lot of beans lost that don't end up on the ground. Where do they go?
It depends on how your beans are planted.
In 7.5" rows a square foot would work. In 30" rows you would be better off measureing off a 30" by 30" square.
A more accurate way would be to count the beans in a 1/1000 of an acre.
In 30" rows that would mean you would count the beans on the ground from one row 17.5 feet long.
For 15" rows it would be about 35 feet of row.
Or count half the length I mentioned above and take it times 2000.
So if you count 100 beans in 8"9" on 30" rows that would mean 200,000 beans per acre. There are about 3000 seeds per pound, so your loss would be about 70 lbs. an acre.
Takes a lot of beans on the ground to make a big loss.

Hi heikemper: Regarding IaGary reply: You might get an easier method by refering to "Planting Rates" for your planter and its manual for seeds per row that you used? If your ending up with similar seeds per row as you planted, you know your loss is about equal to what you planted in bushel per acre. ( or double or half etc) The larger an area you count the more accurate your results.. ag
To make a little spending money in the 50's us kids would go to where the stationary bean thresher was parked to harvest lima beans. When it was moved to another field there was always a lot of spilled beans. Dad would pay us 10 cents a pound for all the beans we picked. We would come home so dirty from the bean straw Mom would sweep us off with a broom. Stan
Average bean seeds per pound of 2,200 x 50 pounds per acre (that is one bag or one unit) = 110,000 seeds per acre. An acre has 43,560 square feet. So a little under 3 seeds per square foot. That is walking the field before harvest, not behind the combine off the seives. That number will depend on the header width.
