Abstract
This study is an investigation of the potential of auxins as indicators of the (micro-)biological activity in soils. Two different methods (colorimetric and high performance liquid chromatography-HPLC) were used to measure auxin-indole derivatives in soils, and their dependence on different sample sizes, pH values, glucose- and tryptophan concentrations in the soil and different temperatures of incubation. The lack of Indole-3-acetic acid (IAA) indicated that the reaction pathway was not completed, Indole-3-acetamide (IAM) could be detected by HPLC if L-tryptophan was added to the soil.
