Abstract

The spatial variability of the microbial biomass content:(C-mic);the,microbial respiration rate (basal respiration)and the metabolic quotient (qCO(2)) was analyzed in sandy Cambisols; and Luvisols in a beech forest in Northern Germany Highest variability of microbiological features and, thus,the:distance of independent samples was around 10 m that is discussed with reference to spatial hierarchy. Structural changesbetween the 10 m and 50 m grid were suggested for the:Ah horizon due to the break Of correlations of C-mic content and the contents of C-org and plant-available Ca,Mg, K and N-c. The C-mic content correlated with the C-org content close to tree trunks and ecotones like borders of the forest and clearings. The qCO(2) did not generally increase withdeclining pH value. High H+ concentrations and C-org,,content in the litter layer near to the tree trunk indicated retarded microbial mineralization rates. High proportion of microorganisms that are resistant to low pH value and:adjusted to readily degradable substrates seems todominate in the soil close to the tree.
