Are organic crops as productive as conventional?
Date:3/25/2008

Dr. Joshua L. Posner, University of Wisconsin.

There continues to be improvements in weed control for organic systems that may close the gap in productivity of corn and soybeans in wet seasons, Posner says. On the other hand, technological advances may accelerate productivity gains in conventional systems that would outstrip the gains in organic systems even in favorable years.

The true question of whether organic cropping systems are as productive as conventional systems is a dynamic question and one that requires continual reevaluation.
