Best Way to Use Bones
I recently came across a web page with some resources listed including how to find raw bones here. This got me to thinking, what would be the best way to get raw bones into the soil to have their phosphorus and calcium used by plants? Burning? Grinding? Just by burying them at the bottom of the hole when you plant trees?
I was also thinking, what about other byproducts like blood, entrails, ?? Sorry if this is a little graphic, it seems like these would be less ideal for burning because they are so wet, but maybe composting or burying under plants in some circumstances could be effective?
