use of well-composted bones in soil


I have several bushel baskets of well-composted bones -mostly chicken. The meat and marrow are long gone. When screening my finished compost, I get well-composted bones. Can anyone use these to build up the nutrients in their soil? I don’t garden myself but don’t want these bones to go to waste.


Thank you for contacting Toronto Master Gardeners.

We do not recommend that bones and meat be placed in home composting piles since they attract pests (rats, raccoons etc.) and can create odours. These bones also take a long time to decompose.

In Toronto, you can put the bones out with other kitchen waste (green bin).  Toronto waste services picks up this material and composts it at commercial facilities which will complete the bone composting process.
