Harvesting forage of the perennial grain crop kernza (Thinopyrum intermedium) increases root biomass and soil nitrogen cycling
Background and aims Emerging perennial grain crops yield less grain than annual crops,
but the economic viability of these perennial systems could be improved if both forage and …
