Green waste problem!!

I've been reading a lot recently about how certain parts of the country (and certain rallies) have experienced problems with green waste.

For those who are unsure what I mean, I'm referring to farmers who are being paid to dump recycled waste from councils into their fields. As the councils are under more and more pressure, to stop landfill, they are in turn turning to farmers to plough this stuff back into their fields.

The problem occurs when these green bins, are contaminated with other stuff, such as silver paper, aluminium cans etc Much of which goes undetected by the council machines, so are being shred into little pieces and strewn across the fields.

As each year goes by and more skips are dumping this stuff on the fields, it is not only risking our hobby, but also has potential health risks to humans who eat the crops.

As all detectorists know, farmers have (and will) plough many different 'by products' into the soil, but this takes it to another level. A couple of hundred tonne of 'green waste' on these fields, will leave junk for years to come. Stories of hundreds of hinges/screws etc are becoming more and more common.

As yet I have not come across the problem on my sites, but it is becoming more widespread. These greenfield sites will soon become 'brownfield' sites, unless something is done quickly to stop it.

It would be interesting to hear peoples views. Maybe as a detecting community we should be doing more, before it gets too late??

Thanks
