More about organic gardening
In nature, every dead thing is deposited in the very place that it dies and there it serves as a mulch. It protects the soil until it finally decays. In time, it is covered and replaced by more dead things.
As these dead things are disassembled by the microbes, the proteins are changed to ammonium gas. Some of the gases are used by the microbes. Some are turned into nitrates. A small amount is used by growing plants and any ammonium not used is absorbed into clay and humus in the soil. It is held for future plant use and little, if any, escapes into the air.
Carbon dioxide is also released as the microbes break down organic matter. Carbon dioxide release is most abundant in warm weather when plant growth is greatest. The carbon dioxide drifts up from the soil surface and is captured by the leaf surface of the many plants growing above. Again, little escapes to the air and what does go over, feeds plants that are growing in areas that don’t have decay processes going on under them.
Mulch also protects the soil from heavy raindrops that settle soil particles together. The broken up water droplets filter through the decaying mulch and collect the nutrients released by the microbes and slowly carry it to the roots of plants that put it back into the life cycle. This layer of mulch also keeps the moisture from moving up and evaporating back into the air.
