Microscopic organisms in the soil perform useful duties, such as decomposing dead plants and thus unlocking nutrients for reuse, trapping nitrogen from the air and changing it into a form (nitrates) that plants can use, effecting transformations in the soil where many elements are temporarily &quot;fixed&quot; and then released later in different form.
