Worm Poop: Black Gold

Sifting your vermicompost material is relatively simple, if a little time consuming. The good stuff, sometimes called worm castings, will congregate at the bottom of the bin. To collect the castings, you can feed your worms heavily on one side of the bin, toward the top, and then wait for about a week.

When all is said and done, we're only after one thing -- black gold. No, we are not talking about oil here. Whatever people call it -- worm castings, tailings, solids, grit, dirt, humus, black gold, or even the "latter end of the digestive cycle," it's all one thing: worm poop.

The special thing about worm poop is that it's highly concentrated into some of the most nutrient-packed fertilizer that you can use. Studies have found that plants fertilized with worm castings saw higher growth rate than those treated with chemical fertilizers. Some farmers know this, and they pay a lot more money for soil with worm castings in it.

With the current trend of eco-consciousness, people are always looking for ways to eat organic foods, and to keep unnecessary waste out of landfills, and recycle.
