Nature is complex. Still, Witt does his best to simplify it. It's what the soil uses in order to make an environment that gives you healthy plants. Humus is the essence of what healthy soil is. Composting is something nature does.
Nature breaks down organic material, turning it into humus.
By managing the environment through composting, Witt and his co-workers can accomplish the same thing in as little as six weeks. By making the environment perfect for microbial action, they assist Mother Nature. This particular row of compost was first composed mostly of onions. It does that thorough of a job. Bacteria, or microbes, break the materials down aerobically, feeding off oxygen and releasing carbon dioxide.
