Horse Manure - is this ready to use?

what had you planned to use it for. It's not rotted as you can see all that straw in it but I believe it's ok for earthing up spuds with

I use fresh muck for growing all sorts of veggies in but I've been castigated on here that I'm playing with fire as there's a risk of salmonella

It does rot down very quickly in those black dalek compost bins    Even leaving it a few weeks on the plot would help it rot down a bit further if it's too wet and smelly. Cover it with a Wickes tarp or old carpet

Looks quite fresh, however you can pile it up and grow pumkins etc in it, just dig a hole fill with soil / compost and plant it will work a treat. In the autumn spread it on the plot were you want it.

Mix it in with your compost heap, it will be lovely next year.

Needs to be moist and crumbly, lovely stuff.  Like crumbled Christmas pudding.  Anything too 'fresh' can scorch.
