9.Composting- nitrogen, carbon, soil biota (bacteria)
Worm composting provides an easy, stink-free way of composting indoors. You can easily keep worms under your sink or in the basement, which is especially helpful in winter when outdoor composting becomes much more difficult. Worm poop, called castings, is biologically active, well decomposed organic material. Worm castings are useful for making compost tea, adding to potting mixes or watering down to spread in the garden. They create a very fine material which will help your soil very much like other composts. A worm bin is easy to make and care for.
