Chaff Lining
The chaff lining technique is clearly the cheapest in terms of capital cost.
Chaff lining involves making a simple chute to divert the chaff fraction (containing weed seeds) into a narrow row in the centre of the harvester instead of onto tramlines.
The chaff is then left to mulch while the residue can be chopped and spread to maintain ground cover. Although suited to controlled traffic systems, chaff lining can work in non-CTF systems if the harvester operates along the same runs for consecutive years.
