Eukaryotic algae and terrestrial cyanobacteria compose, together with bacteria and fungi, the main part of the plant mass in the soil. According to Shtina (1974), the algal biomass in soils of temperate regions varies from 150 to 500 kg · ha-1. As phototrophic organisms, algae accumulate organic matter, they stabilize soil aggregates, have inducing effects on the development of soil-fungi and bacteria, and serve as sources of energy for the soil-microfauna.
