Mine too. *Bloody good stuff is horse poo, but the Brits have had problems
with weed killers spread on pastures contaminating the poos - it's then
gone on to kill plants in gardens. *I don't have this problem in my
country and it appears that the worst thing to do with the weedkiller
infested British horse poo is to pile it and try to 'age' it - the poison
apparently doesn't break down going that route but does if spread.

What poison is it?

On our plots, Manchester UK, it was an herbicide call Aminopyralid
introduced by Dow Chemicals a few years ago to treat broad leaved
weeds in commercial crops. The herbicide binds strongly to plant
material which when grazed by or fed to cattle and horses in
feedstuffs such as silage or hay can pass through the animals without
breaking down. We've been advised to rotavate or dig over the soil
several times between summer and autumn when the soil is warm. The
contamination is widespread here - seen in Scotland, Wakefield and
Cornwall.

Luckily I was on holidays when we got a load - I was upset I had
missed it. Not any more!! The RHS wrote to us advising us to 'scrape
off' any loose manure! What a shame ...
