Start planning your nitrogen management strategy for fall-planted wheat now (and consider using a N-rich reference strip to manage your N more precisely)
Recent UCCE research has illustrated the value of in-season applications of nitrogen (N) fertilizer, particularly applications made at the early vegetative growth stages. This is typically the stage of growth when N demand from the crop is...
