is it ok to bury dead animals under fruit trees

Every once in a while I come across a dead critter in my yard or by the road.  Would it make sense to bury the carcass under the drip line of a fruit tree?

a few months after moving to this place we found out that the local pet cemetery is at the west fence line on my property, I couldn't make this up if I wanted to, well the walnut trees are doing real well there

I see no problem with burying dead animals under trees. I've done it plenty of times in the past.

From a permaculture point of view, you may not wish to bury chemically euthanized animals near food trees. Sodium pentobarbital is the primary drug used fur euthanasia, but others including various tranquilizers, ketamine, and others are frequently used. I'm not sure about the others, but sodium pentobarbital is rather persistent in the environment. In the past, I used to bury euthanize animals under pine trees. The trees grew absolutely great.

Whenever a pet died when we were kids, it was either buried and something planted on top or buried under an existing tree or shrub. Often it was a fruit tree. No problems noted so far.

It can work great. Just be careful of animals digging it up

In Australia it’s traditional to bury a bull’s heart under a newly planted passionfruit vine. They like the iron.
