628 Symposium --The Role of Carbon and Energy Budgets in Organic Systems

Oral Session
A08 Integrated Agricultural Systems
One of the key issues in the sustainability of organic farming systems is the positive overall energy balance and maintenance or enhancement of soil carbon in a system necessitating occasional tillage operations for weed management. Researchers from key institutions in the U.S., Canada and the E.U. will present data on balance sheets of energy, carbon and other nutrients on organic farms compared to conventional systems relying on fossil-fuel inputs.
