Soil microflora
organisms ranging from microscopic single-celled forms to multicellular forms 100 feet (30
meters) or more long, distinguished from plants by the absence of true roots, stems, and
leaves and by a lack of nonreproductive cells in the reproductive structures. Today, algae are
used by humans in many ways; for example, as fertilizers, soil conditioners and livestock
feed.[54] Aquatic and microscopic species are cultured in clear tanks or ponds and are either
harvested or used to treat effluents pumped through the ponds. Algaculture on a large scale is
an important type of aquaculture in some places. Maerl is commonly used as a soil
conditioner.
