Do I still need an inoculant on my old rotated soybean land?
Yes. Since 1992, Becker Underwood has commissioned many trials with Soybean Extension specialists in the US soybean growing belt. From 1995 to 1997, HiStick returned a mean yield benefit of 2.64 bu/acre on old rotated land. Assuming seasonal soybean and HiStick prices, this returned a healthy $16.40 net benefit / acre to the farmer.
