Potassium Management during the Rotation from Alfalfa to Corn

Matt A. Yost; Michael P. Russelle; Jeffrey A. Coulter; et al. Agronomy Journal 2011. doi:10.2134/agronj2011.0183

Other claims from this paper (8)

Intervention effect Potassium did not improve alfalfa yield.
Intervention effect Potassium did not improve alfalfa relative feed value or quality.
Association Each 100 kg ha −1 increase in available K index raised corn grain yield by 0.5 Mg ha −1 under carryover K alone.
Association Each 100 kg ha −1 increase in available K index reduced corn stover yield by 0.4 Mg ha −1.
Association Available K index did not affect corn silage yield under carryover alone.
Intervention effect Additional K applied to corn increased stover yield by 10%.
Intervention effect Additional K applied to corn increased silage yield by 8%.
