ProveN ProveN® 40 (Pivot Bio) is a biologically-based product containing N-fixing bacteria claiming users reduce their supplemental fertilizer nitrogen. This product was compared in combination with Xyway and Vitalize Silver and separately in an on-farm eFields trial in Fayette County in 2022. Despite having a 3 bu/ac spread between some treatments, due to high variability in the field as a result of uncontrollable factors, no statistical difference was seen between treatments.
