Methods: We investigated total and plant-available soil N, P, and K stocks and the nutritional status of Picea abies concerning these elements on 14 forest soil monitoring sites in the Bavarian Alps. Results: Mean soil N, P, and K stocks are 8.0 Mg Nha−1, thereof 14% bound in the forest floor, 1.7Mg P ha −1 (2% in forest floor), and 42 Mg Kha−1 (0.2% in forest floor). Citric acid-extractable orthophosphate and exchangeable K contribute to 3 and 0.7% of total P and K, respectively. Spruce N, P, K, and Mn nutrition differs considerably among sites, with Rendzic Lithosols being most critical, whereas trees on deeply weathered soils are well supplied. Conclusions: According to our estimation, the forest is characterized by an insufficient supply with N, P, and/or K at about 30, 20 and 10% of the forest area in the Bavarian Alps, respectively. A large part of the Bavarian Alps can be judged critical and prone to nutrient shortage in the course of humus degradation and associated SOM losses.
