Protozoa

Protozoa (mg PLFA per kg) are single-cell micro-organisms that contain a cell nucleus (eukaryotes). The most important function of protozoa is to make nutrients available to the plant by "grazing" on microorganisms (mainly bacteria). Protozoa activity is highly dependent on the presence of moisture in the soil. The radius of action of protozoa is limited to water films and water-filled pores.
