Abstract The paper deals with recent measurements of NH3 applying an improved Indophenolblue method after Bertheolot. Aircraft measurements show a marked difference of the absolute concentration of NH3 between summer and winter. This seasonal difference indicates the effectiveness of biogenic NH3 sources during the summer months. Quantitative analysis of the source strength of different soils show the influence of the temperature at the ground and of the pH-value of the soil. The main sources of NH3 are continental, but microbiological activity in the soil alone cannot fully explain the NH3 flux into the atmosphere.
