Toxic Horse Manure

The allotmenteering world has been rocked recently by the news that a certain herbicide has somehow made it into livestock feed and bedding – the result is that many manure sources (and straw) including some certified as organic are now veggie killers.  Whilst it is noted that some vegetables are hardy enough not to be visibly affected the suspected culprit (aminopyralid) has a long soil life and the veg may be unsafe to eat (I stress the may).

Whilst the above guardian link suggests the company Dow agro have not confirmed vegetables are unsafe I can only find an article on their site suggesting back in November that farmers should not sow potatoes on contaminated land.

Regardless, the general advice from forums is to lay the affected manure as thin as possible to allow the chemicals to leach out and not to grow anything for a year.  At least it’ll keep the weeds down I suppose…
