For lack of time right now I am just burying my kitchen scraps a bucket at a time in places I plan to plan in later. What are the biggest drawbacks to this other than the obvious lack of big diversity in materials composted?
I second it being dug up
in my backyard that is called "party time"
but I do something like that with some 5 gallon buckets. i drilled holes in them got screw on lids and bury them with just the top sticking out. i add in some compost worms and worm bedding and that is where some of our kitchen scraps grow. I like to put these near fruittrees or tree collards and I don't seem to need to really do anything to maintain them. it took some trial and error to get the moisture and everything worked out right and in the beginning a few times i had to pull a bucket out and remix the contents with some dryer stuff but once i get them balanced the worms are moving their castings out of the buckets and the plants near them are are putting roots around the buckets and I now have a nice worm population in the mulch where I had none before because where I live there are lots of things that love to eat worms!
I have more or less solved the digging problem by making a big rock pile over the buried stuff. Lizards like these rock piles, which get moved around the garden rather slowly, as we don't generate much material that needs to be buried.
