Regimen often includes cover crop then burn down herbicide (and/or tillage) before planting. I am 100% in favour of perennial crop agriculture, but this is going to present entirely new weed mgmt problems for the kind of industrial scale cash crop agriculture this is apparently for. Annual planting gives the farmer a chance to manage weeds (and soil structure etc) every planting season.
