A nearby farmer got me a load of bones, really big ones. I suppose cow legs or something like that.
How can I use them for soil improvement? I have no dog.
I keep on finding information about crushed bones, but I am no Hercules.... If I start whacking them with a sledgehammer, my own bones may quickly be added to the pile.

Whathever you are, be a good one.

Good question!

I haven't tried it, but I heard once that burning bones in a hot fire makes them crumbly and easy to crush. The internet seems to agree. I think your cow foreleg bones will need a lot of heat and time. Let us know if it works!

I have read here on the forum that a lot of folks compost bones and make biochar instead of making bonemeal.

Here are some helpful threads for you or others:

Thanks, Anne! The first link is excellent. Haven't looked at the others yet.

I should have just checked Permies instead of bothering with the rest of the internet. Haha.

I burn all of our scrap bones in the woodstove. Afterwards, they crush easily. A campfire would work just as well.

I trust the information here on the forum a lot more than I trust the internet.

A lot of times I search the web for something like "Paul Wheaton biochar" or what I am looking for and come up with good links on permies and YouTubes.
