Humus

Humus is the organic component of soil, formed by the decomposition of leaves and other plant material by soil microorganisms. This soil contains the nutrients for plants to grow. The better the humus in the soil the better your plants will grow. In nature, humus is constantly introduced into soil as plant debris, dead animals, and other organic matter that decomposes on the ground.  (http://www.green-trust.org/wordpress/2010/08/15/what-is-humus/)
