Burnt Horse Muck - good or bad?

[toby6668]

I have just found a source of well rotted horse muck but the owner (who couldn't find anyone to take it!) had tried to burn it in a big heap. The outer 4 inches or so is a little charred, but is fine under this top layer. I'm wanting it as the main material to fill some new raised beds. Is there likely to be any problems caused by the burnt stuff? My gut reaction is that it will be fine...but would appreciate any advice
Thanks - from a Newbie.

Should be fine. I'm not surprised it didn't burn well though

I agree with rustylady

Thank you. My big brother tells me that horse muck isn't great because it can contain a lot of weed seed. Is this much of a problem? Thanks for your help.

Not a problem at all - it's great for enriching your soil. Then there's the added advantage, that in a couple of years, you'll soon be an expert on all growth stages of Couch Grass, Nettle, Dandelion, Dock, Sow Thistle, Cleavers...

But they're all compostable!

Errrrrr. Not sure what to do now. Seriously, am I going to regret using this? Feel a bit daft asking. :-)

Oh for goodness sake Toby. Use the stuff - you'll get weeds on your plot whether you use it or not.

Ha. Brilliant. Just look at my plot not worried about the muck now.

If it gets hot when its composting (needs a 1m cube to get hot enough) you kill the vast majority of the seeds. If its then sat for longer anything not dead would grow out the compost...
