Hey y'all! I have access to free aged horse manure and I am keep on coming across a problem. I ask each person if they use antibiotics or a dewormer and so far all of them use a dewormer. Obviously, this is a big issue. My question is this...if it has been aged for a year do you think it is still an issue?


For those who want to know, the free manure is found off of Craigslist.

Thanks in advance!!

I can't answer your dewormer question, hopefully others will chime in.  You may also want to ask about what the horses are eating.  Persistent herbicides on horse pastures can be eaten by the horses, pooped out, composted and still kill your garden plants.  See this Mother Earth News article for a bit more info.

It's hard to look a gift horse in the mouth but you have to wonder what else has been in that mouth

It's my understanding the dewormers are short-lived and can be assumed to have broken down within 60 days of aging (hence why they have to keep giving the horses the dewormer). That's standard of practice with vermiculture (worm farming), which means it won't kill composting worms.

As Kyle points out, Worming meds break down well within 60 days. Herbicides on pasture lands are less frequent than insecticides in my experience, neither of them are much good for compost.

If you take aged manures and compost them in a hot compost heap, you will degrade just about any "cide" residues that might be present.

I use horse manure all the time and worry about persistent herbicides to the point that I test, but wormers and the like not. After my manure has been sitting for a few months there are generally worms and grubs in it, which makes me think any pesticides have broken down like they're supposed to. After four years of horse doo on my main patch, I see at least as many bugs, worms, pollinators, and vertibrate friends (snakes and skinks) as my wife does in her patches not far away, which get very little (she likes more straight compost etc.). I'd say go for it!

Thanks y'all! That helps out a lot. 😊
 
When it is used for evil, then watch out! When it is used for good, then things are much nicer. Like this tiny ad:
