Humus is the magical dark stuff of soil that helps plants grow. Or is it?
Microorganisms in the soil facilitate the decomposition of plants, bug bodies, and other living things in a process called humification. Humification occurs in the soil and in compost piles. Along with microorganisms, worms, nematodes, and other tiny critters help this transformation along. The black, rich, earthy smell from premium soil is the humus, or organic matter. (The black color is from carbon.)
When you add organic matter to the garden or compost pile, you are feeding the organisms that make nutrients available to your plants.
