Notes:
Summary Dehydrogenase activity was studied in typical soils of the Northwest German Lower Plains in order to test some criticisms raised by nannipieri et al. (1990) about methodology. We found that in the same soils with the sampe crop, dehydrogenase activity varies significantly. In the field dehydrogenase activity was dependent on the soil type and not on the cropping system. There is no adequate explanation of these findings. Dehydrogenase activity is a parameter of soil microbiological activity and is influenced by many factors. Either purely accidental the results are or dehydrogenase activity is affected by unknown ecological interactions and by the composition of soil microflora. We conclude that without simultaneous investigations of other microbiological parameters (microbial biomass, ATP levels, enzyme activities, etc.) the measurement of dehydrogenase activity creates confusion and may impede valid ecological comparisons of soils.
