Description :
Here, the AA. investigated the NO3-N concentration and its seasonal variations in the baseflow headwaters in Japanese coniferous forests with different N saturation status in 5 regions (Nagano, Tokyo, Aichi, Kochi and Mie). They also investigated the associations between seasonal variations of the NO3-N concentration in baseflow with vegetation growing season (growing season or dormant season). Finally, they propose a robust N saturation indicator suitable for Japanese coniferous forests.
