In a 40 year old pine stand, soil solution was collected continuously with suction cups from 50 and 200 cm depth over a 42-month period following the surface application of lime and K/Mg-fertilizer. K and Mg showed a much higher mobility than Ca, which hardly increased in 200 cm depth even after 42 months. After an initial nitrate peak, concentrations decreased but remained elevated throughout the entire study period. In 200 cm, Al-, Mn, and Cd-concentrations increased due to exchange processes in the top-soil. Continuously elevated sulfate concentrations in 200 cm indicate S-mineralisation from human decomposition.
