Being 80 miles or so West of you, Brisel, the numbers here usually stack up.adding up the cost of remedial cultivations to repair the damage by the straw crews and the loss of OM and K and straw needs to be a good price.
The most difficult thing always to remember here is to re-invest that portion of one's straw income necessary to replace the nutrients lost, rectify the damage, etc, etc (typically 50-60% here) and not to allow one's accountant to divert it all towards a new combine.
