Community Structure of Soil Microorganismsnt of the content of the phospholipids has also been used to estimate microbial biomass in sediments and soils (Smith et al. 1986; Baath et al. 1992; Korner and Laczko 1992; Zelles et al. 1992; Frostegard et al. 1993; Hill et al. 1993).

The ATP content of microorganisms can be widely divergent depending on their metabolic activity (Fairbanks et al. 1984). Jenkinson (1988) pointed out that ATP contents of different soils can only be compared if such parameters as

GEM

Nitrogen MineralizationThe conversion of organic nitrogen to the more mobile, inorganic state is known as nitrogen mineralization. Microorganisms with different physiological properties take part in this process. In the first step, ammonium is formed from organic compounds (ammonification); in the second step, ammonium is oxidized to nitrate (nitrification).

Ectomycorrhizae“Mycorrhiza” describes the symbiontic relationship between plant roots and fungi. Depending on the type and intensity of the contact between the two partners, one can differentiate between ecto- and endotrophic mycorrhizae. A detailed survey is given by Harley (1991).

APRON

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.
