Dynamics of Soil Organic Matteral soil (Schachtschabel et al. 1989). The organic matter subjected to microbial decay in soils comes from several sources. The decomposition of organic matter provides energy for the growth of microorganisms and supplies carbon for the formation of new cell material.

Non-Symbiotic Nitrogen Fixationd ., nitrogen fixing abilities have also been revealed in anaerobic phototrophic bacteria as well as in many cyanobacteria, facultative anaerobes, autotrophic and methylotrophic bacteria, and desulfurizing and methanogenic bacteria in the last decades (Schlegel 1992).

Nitrification and Denitrificationely responsible for nitrification in soil with a pH above 5.5 (Focht and Verstraete 1977), at a lower pH there is evidence for the presence of acid-tolerant heterotrophic nitrifiers (Schimel et al. 1984). The heterotrophic nitrifiers (e.g. few bacteria, such as strains of ., and fungi, such as .) do

In most soils, the organically bound P-fraction is higher than the inorganic. Among the organic phosphoric acid esters, the largest fraction in the soil is phytanic acid or phytin (Halstead and

Enzymes Involved in Intracellular Metabolismion reactions into water and oxygen. Since aerobic organisms predominate in non-compacted and non-waterlogged soils, catalase activity was used to characterize soil microbial activities (Beck 1971). Catalase was also the first enzyme that was investigated in soils (Woods 1899, cited in Skujins 1978)

Adenosine Phosphatescarriers that are generated during exergonic reactions and used to drive endergonic reactions. At the substrate-level, phosphorylation, and in the electron transport, chain oxidation reactions, supply the energy for the phosphorylation of AMP and ADP to ATP. The ratios of these three adenylates are
