Values in brackets are variations relative to the reference system. Nearly-direct margins were calculated for each crop by multiplying average crop yield and harvest price and substracting average herbicide costs and mechanization costs. Nearly-direct margins were then calculated over the rotation as the average of the individual nearlydirect margins of each crop of the rotation.
