Effect of Silicate Rock Dust in Forests: Result of the Experiments in the Forest of Arenberg-Schleiden after Five Years

The advantage of rock dust is that it is a natural, raw material, and carrier of numerous minerals and trace elements with long term effect. The nutrients are released slowly and gently during the process of natural weathering in the forest ecosystem (without fertilization shock). In the following, we report the latest results of the experiments in the forest of Arenberg-Schleiden.
