- Nitrogen (N)
- Phosphorous (P)
- Potassium (K)
I have been looking around on-line trying to find out what types of nutrients that clams, muscles, oysters, and fish skins add to the soil. I'm still not sure. Oysters seem to be high in calcium carbonate which is useful to a degree. I know the goal for high quality soil is something like:
- Nitrogen 24%
- Phosphorous 6%
- Potassium 6%
I suppose it is time for us to get a soil test kit so that we can regularly analyze our compost and different garden beds.

Definitely get a soil test kit; without knowing where you live the underlying rock is different in the area. Take a look at the maps in this PDF for rock types: http://geoheat.oit.edu/bulletin/bull23-4/art5.pdf
New Mexico Tech has a great page about Elephant Butte that has some maps: http://geoinfo.nmt.edu/tour/state/elephant_butte/home.html
If you are in a limestone area you probably don't need any shells in your soil (for calcium).
