Table 4.

Input and operational costs as well as margin of selected cropping systems with occasional mouldboard ploughing from the Burgundy case study (adapted from Ballot, 2009).

Reference system OWB 76 262 338 286
OWBOWb 82 258 340 (+1%) 296 (+3%)
OWBOWp 67 253 320 (−5%) 289 (+1%)

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.
