False . Microorganisms and humus have major impact on soil health. Humus contains important nutrients needed for plant growth, including nitrogen. And it's not just that humus contains nitrogen, it provides it in a form that is highly usable for plants. Humus also gives soil the necessary structure and a crumbly and loose texture so oxygen can get in and reach the plant roots. As microorganisms help break down organic matter, they release essential nutrients and carbon dioxide into the soil, fix nitrogen and help transform nutrients into mineral forms that plants can use through a process called mineralization.
