Worm’s Way Alaska Fish Fertilizer is a good example of this. It is made from 100% pure fish compound, from one of the cleanest oceans around. It offers a great way to feed your garden everything it needs, without having to resort to store bought soils that are full of dangerous additives.

The only real problem with this product is that it is made of fish, and it is hard to ensure that fish have had no chemical exposure. Just look at the common issue of mercury found in most fish. Some vegetarians may also dislike it, obviously, given the fact that it is made from a once living creature that they usually avoid eating. Otherwise, it is safe, effective, pure, and affordable.
