What is difference between humus and compost?
In composting, the material decomposes as microorganisms digest the organic material in the presence of oxygen, generating heat as the materials break down. This is known as aerobic decomposition. By contrast, humus is formed by the decomposition of materials without oxygen present.
What would be the best source of humus in soil?
