Doing this completely without
herbicides is a tremendous challenge, one that our research has only
partially accomplished. Until that goal is realized, I truely believe that
the trade-off between the possible ecosystem disruption of careful herbicide
use and the certain, major disruption of tillage is positive one. Ask any
I'm curious about how/why you would grow a
cover crop in a no tillage system? Are you
talking about land at extreme risk of water
erosion in the non-cropping season?
I agree that soil erosion is one of the pervasive
and and permanent treats to sustainability.
Are there any large scale no-till cropping
systems that minimise herbicide use? Or are
you talking about using a "little" less
than conventional systems?
