Direct combine soybeans with a flex header when seed moisture is <14%. Seeds are prone to damage at <12% moisture. Carefully adjust cylinder speed and concave clearance to minimize cracking and
splitting of seed.
Measure harvest yield loss regularly using the Bean App Soybean Harvest Loss Assessor. Over 80% of harvest losses occur at the header. Reduced harvest speed at <5 mph will greatly diminish losses (4 beans/ ft2 = 1 bu/ac).
