Did you know?

It's not too late to score all of your points in the EndZone!

Got 10,000 bushels of 9% beans? End zone can make you up to $6000 by helping you to rehydrate your soybeans  to 13%. The bins already full, no problem .  We have a system that allows us to get a probe into your bulkhead door and another monitor probe in the top of the bin, to allow differential moisture measurements. Talk to the folks at Farm Shop MFG to learn more 712-219-0148.

Producers may want to recondition soybeans harvested at lower moisture contents to bring the moisture up to the market standard of 13%. On a 40-bushel-per-acre yield, harvesting soybeans at 9% moisture content, rather than 13%, is equal to 1.8 bushels of lost weight per acre. At $9 per bushel, that is $16.20 per acre.

Just as grain is dried with bin fans, soybeans can be reconditioned by operating fans during periods with the desired air temperature and relative humidity. Reconditioning requires high airflow rates for several weeks using air with an average relative humidity of about 70% to recondition soybeans to 13% during normal fall temperatures of 30°F to 60°F.
