Biochemical breakdown of organic waste

Organic residues which have been mixed

Returning of plant nutrients

10:1-12:1 mean there is 10 units of carbon for each unit of nitrogen in the substrate

It is the plant kingdom

Plant roots, macro algae

Bacteria, Actinomycetes, fungi, algae

The animal kingdom

They are longer than bacteria

Fungi and the roots of higher plant is called

They are more abundant in dry and tropical soil

Unicellular but larger than bacteria

A branch of science dealing with the study of soil microorganisms

Smallest organisms in the soil

Abundant after bacteria

Can make its own nutrients through a process of photosynthesis

Eukaryotic organisms, maintain equilibrium in soil microbes

Smallest member of protozoa

Larger than flagellates, does not have permanent appendage

Largest of the group of protozoa

Lead to desertification and loss of soil biodiversity

Lead to a slow death of most soil organism due to nutrient depletion and disturbance
