When wheat never dies
Could commercially viable and tasty perennial crops like Kernza be regenerative agriculture's holy grail?
Much of today’s crops are designed to either provide high yields through fertilizer treatment or to be part of a cyclic rotation between nitrogen fixers and net users.
A crop that never is tilled and is not part of a rotation to enhance yields will present lower returns and special challenges with weeds, with roots bound to less than ideal soil, resulting in less vigorous growth.
More land, more crop variety, less efficiency and more equipment intensive harvesting may be ahead.
