A chaff feed stream conditioning system for installation in a combine having a crop residue handling system that operates to separate crop residue into a straw feed stream and a chaff feed stream which may include weed seeds, where the straw feed stream directed to flow towards a straw spreader or chopper and the chaff feed stream directed to flow toward a mechanical devitalisation system or other processor, the feed stream conditioning system comprising:

• a separation mechanism located between the straw feed stream and the chaff feed stream, the separation mechanism configured to impede material from the straw feed stream from entering the chaff feed stream or otherwise reaching a downstream end of the chaff feed stream;
• and
• one or more magnets located at one more points along straw or chaff feed streams and/or upstream of crop residue handling system to capture at least some metallic matter entrained in the crop residue and thereby reduce an amount of metallic matter in at least the chaff feed stream or otherwise reaching a downstream end of the chaff feed stream.
