The Soil Biota
Earthworms
Earthworms are classified within the phylum Annelida, class Oligochaeta.
Enchytraeids (potworms)
Enchytraeids, also called 'potworms', are small (1-30mm), unpigmented worms.
Microarthropods
Soil micro-arthropods include small invertebrate animals with a exoskeleton and segmented body that are visible to the human eye with some magnification for identification.
Nematodes
Nematodes are non-segmented microscopic worms. They are among the most numerous and diverse of the multicellular organisms found on earth.
Fungi
The kingdom Fungi is one of the most diverse groups, ranging from one-celled yeasts to actually the largest and oldest organisms on earth. They are widely distributed in nearly all habitats on Earth.
Bacteria and archaea
Bacteria and Archaea are prokaryotic organisms, in most cases microscopic and single-celled, except some Cyanobacteria and Actinobacteria that form mycelia-like structures. Despite their relatively simple structure, their diversity and functionality is enormous and they are the most efficient organisms in terms of survival and dispersion.
Soil microbial processes
Soil microbes are extremely diverse and regulate key processes for ecosystem functioning that are essential for ecosystem health and resilience.
