Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT On its 100th anniversary in 2026, the German Soil Science Society (DBG) is looking back not only on an eventful history with traditions and impressive achievements but also with painful interruptions and ruptures. One curious fact is that the DBG was initially founded as the national section of the International Soil Science Society (ISSS ...

Food Security Versus Environmental Health: The Nitrogen Dilemma
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background On ca. 10% of the forested sites in the Bavarian Alps (Germany) mountain, forest soils (so‐called folic histosols) are characterized by thick organic layers overlying poorly weathered calcareous parent material. Aim These organic layers play a critical role in releasing water and nutrients for vegetation, yet they are also sensitive

Paul Vageler (1882–1963) and His Pivotal Role in Germany's “Colonial Soil Science”
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT This essay examines the role and activities of the German–Brazilian soil scientist Paul Vageler (1882–1963) in Germany's colonial policies and ambitions between 1909 and 1945. It highlights his scholarly achievements during the German Empire (with colonial possessions), the Weimar Republic (colonial revisionist thinking following the loss of ...

Temperature Sensitivity of the Humus Form Tangel
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Tangel is an important humus form in mountain forests, particularly in areas of carbonate rock. To gain an initial understanding of its sensitivity to rising temperatures, a respiration experiment was conducted. The derived Q10 values (3.35–3.36) are comparatively high in relation to values reported in the literature, indicating that Tangel is

Holocene vegetation change and fire–plant diversity shifts in Mediterranean France
Journal of Quaternary Science, EarlyView.ABSTRACT Changes in fire activity are recognized as a major threat to biodiversity and vegetation communities across the Mediterranean Basin. However, long‐term fire–vegetation interactions remain poorly investigated. Here, we combine a high‐resolution charcoal record with pollen data from the “Étang des Aulnes” lake (southern France) to reconstruct ...

Journal of Quaternary Science, EarlyView.ABSTRACT Upland farming in Europe is frequently assumed to have been limited and precarious, despite relict spade‐dug ridges providing firm evidence of past crop growing. Direct evidence for crop types in post‑Medieval to Modern (~since 1500 CE) uplands is rare; yet, in Ireland, relict spade‐dug ridges that date to this period are commonly interpreted ...
