GM field trials, Glastonbury Festival waste becomes farm fertiliser
UK field trials have shown that a variety of GM wheat designed to repel aphids has not worked. Plus the farmer who is turning Glastonbury Festival waste into farm fertiliser.
UK field trials have shown that a variety of GM wheat designed to repel aphids simply hasn't worked. The idea was that the wheat would release a chemical signal that mimicked the aphids in distress. In the lab, it kept the aphids away but in the field they started to ignore the smell. Charlotte Smith considers where this leaves GM crop trials in the UK.
This weekend sees 177,00 music fans head for the Glastonbury Festival on a dairy farm in Somerset. But what happens to all that waste from the portable loos? Emma Campbell meets the farmer who's recycling the waste from compost toilets into fertiliser for the fields - proving that where there's muck, eventually there's money!
