Does nitrate discharge occur in a forest soil under beech? What is the nitrate dynamics in the soil profile between 0 and 180 cm depth?

Leachate extraction with suction plates for determination of nitrate concentrations. Measuring depths are 0, 15, 30, 60, 120 & 180 cm at the Conventwald location. The experiment is part of the “Intensive Ecosystem Monitoring” at a total of 20 locations in Baden-Württemberg.

We are happy about this first application of our nitrate monitoring concept in forests. So far, our extraction technology has only been used under arable land (for further information see here).
