So my wife and I are starting a vegetable garden this spring. Starting small, with the basics (like tomatoes, squash, bell peppers, carrots, etc). One thing I am curious about is fortifying the soil to make sure that the micronutrients aren't depleted. How does one go about replenishing things like selenium in the soil?

I just don't see organic fertilizers, compost, etc, as doing a sufficient job of replenishing micronutrients. Any ideas?
