I only found out about it when reading the Guardian this morning and seeing a photo of what looks like our withered and misshapen broad beans. At least we now know why they did so badly.
We have two large raised beds - used manure from a friend's cow shed on one, and bought organic manure (because said friend was slow at giving us more manure) for the other. The bought manure was obviously contaminated - bed 1 did well, bed 2 has done terribly.
