calamagrostis angustifolia/カリウム

From May to October 2004, the seasonal changes of K, Ca, and Mg contents and accumulation in Calamagrostis angustifolia, the dominant species in the typical meadow and marsh meadow communities of Sanjiang Plain, were studied. There was a greater difference in the seasonal changes of K, Ca, and Mg

In many successional series, grass species play an important role in mid-successional stages. Using calcareous sand ecosystems in the northern upper Rhine valley (Germany) as a model, we analyzed successional trajectories and the factors that determine their direction. A 5- to 7-year study of 23

Four typical wetland types (i.e. wetlands with the following dominant plant species: Calamagrostis angustifolia + Salix brachypoda, Calamagrostis angustifolia, Carex lasiocarpa and Phragmites australis) of the Honghe reserve in Sanjiang Plain were studied to investigate the distribution of soil

Natural abundances of nitrogen isotopes, δ15N, indicate that, in the same habitat, Alaskan Picea glauca and P. mariana use a different soil nitrogen compartment from the evergreen shrub Vaccinium vitis-idaea or the deciduous grass Calamagrostis canadensis. The very low δ15N values (-7.7 ‰) suggest
