Microbial Energetics in Soils

6 Conclusions

Microbial communities in soil represent a high diversity and density of biotic interactions. Fungi and bacteria dominate the microbial biomass and the potential activity is generally restricted by low nutrient availability in soil. Fresh plant residues and exudates provide the main internal source of nutrients in natural ecosystems. Substrate input rapidly stimulates catabolic and anabolic processes leading to high metabolic and microbial quotients. The respiratory quotient is additionally increased under growth conditions. The interaction between respiration, microbial C and organic C content in soil is discussed with reference to an integrative energetic indicator for soil organic matter quality.
