Meat Compost

was just wondering does any of use compost meat and dairy products?
were does it be stored?
does it have to be airtite?
what does the finished product look like?
an does carbon materials have to be added to make it look more like soil?
ive seen animals rot an it seem to make a liquid mess!

Well blood meal dried up blood and bone meal boiled bones grinded to fine powder used to be primary fertlizers .....you can compost meat works out fine turns into compost just like anything else i know some people that composted a horse they just threw it in there pile ..But the reason most people dont compost meat is it attracts animals scavengers

This is great stuff on this thread. Take the time to read it. You'll find the answer to your questions. A good search criteria to find info on this is MEAT.

I do know that professional worm growers don't use Dairy or citrius by-produces due to the cause of harmful fungus & bacteria created. Also, citris oils is a stong acid. Meats broken down naturally, via an animal stomach seems to work well to begin the compost process.

Generally meat should be avoided in your garden variety compost pile. Blood and bone meal are one thing, maybe even a stripped carcass, but when you're talking about straight animal fat and protein I would have to figure there's going to be a heck of a lot more consideration. First of all, the basic principal is that any animal by-product used in crop production be it manure, blood or bone meal should come from a strict herbivore. If you think about how a ruminants digestive system works, you might realize that their manure is essentially a plant/microbial by-product. The cow or the sheep eats plant material; it masticates to break this material down (and swallows, regurgitates and masticates again) but the bulk of the 'digestion' which takes place is carried out by the gut flora (various microbes, primarily anaerobic). Once the manure leaves the animals behind it is still nutrient rich, still has undigested plant material and is still teaming with microbes, so the decay or composting continues.

The issue with meat in compost is much the same as with using the excrement of carnivores and omnivores: bad anaerobic microbes, namely E. coli. And I can't imagine a compost pile with meat in it would smell sweet and earthy like regular plant compost should.


Citrus fruits AFAIK are just fine, in compost anyways, though vermi might be a bit different. Saprophytic fungi will decay lemon/orange/lime peels over time; they are usually the first ones on the scene and will begin the decay process (they also like the acidic environment). Bacteria don't come in until a bit later. This doesn't apply to everything (and there are always exceptions), there are just certain substances which bacteria lack the enzymes to break down (ie: lignin, cellulose, chitin) and bacteria tend to prefer alkaline environments. Fungi are also necessary to open materials up for decay by bacteria, which can only act on the surface of a material. The more broken up a material is in the first place, the faster the bacteria can get to work.

When composting meat you have to use manure, bedding/sawdust, and a lot of water, NO green plant material.

Finished product is basically a super nutrient enriched plant fertilizer. My plants love it.

why no green plant material?
what way do you break it down do you have it in and open pile or a sealed container?

All i can say is gross

I've been gardening a loooong time................never heard of using meat compost. What I can tell you is that it's always been cautioned to never put meat scraps in compost. I do make my own for vegetable gardens, never using meat. Scavengers are one consideration but bad bacteria such as e-coli and salmonella is another consideration. It's one of the reasons you don't use dog crap or human feces on vegetable gardens..

It won't break down with the other materials and I do my composting in a big pile.

For anyone that thinks this doesn't work, here's my last grow using meat compost.

As I said this thread answers pretty much all of these questions.

Me too. I've always heard to never use raw meat or manure from a carnivore because of all the pathogens. Might not be bad for plants, but prolly not so good for humans.
However, I know a lot of peeps do compost fish and there's compost made from dead turkeys so it can obviously be done.

Double Whopper with cheese? How's about a side of fries with that.

Generally people avoid meat because of pathogens and insects we don't want around like flies.

If you want to process meat may I suggest Black Soldier Flies? They eat it all and also keep the unwanted insects out of the picture.

In Compost pile meat attracts animals that often cause problems for gardens and even your pets.

Generally if you have an active pile adding a few small animals isn't a problem but trying to compost a pile of chickens may well make you very unpopular in your neighborhood.

But we use fish meal, bone meal, blood meal, feather, hoof and horn and other such things but as always everything in moderation.

what abut human placenta ? it has stem cells dried and ground into powder O,o

my compost pile got a bunch of meat thrown into it and i didn't realize it until this morning when i turned the pile and it was full of maggots. do i kill them with poisons or let them eat until there is nothing left? maybe add some ammonia nitrate and burn the little suckers out of there? how would you folks handle the problem, or if you even think it's a problem?

Maggots will feed on all kinds of organic matter, not just meat. I'd just let them do their thing and not chance poisoning your compost heap. I'm pretty sure their waste left behind is also good for plants.
