Short-rotation forestry is of interest to provide biomass for bioenergy and act as a carbon sink to mitigate global warming. The Poplar tree (Populus × xiaohei) is a fast-growing and high-yielding tre...
Although CO2 fertilization on plant growth has been repeatedly modeled to be the main reason for the current changes in the terrestrial carbon sink at the global scale, there have been controversial f...
The paper presents the evaluation of data on precipitation totals and on SO42 –concentrations and S-SO42 – fluxes in lysimetric waters in a submontane beech stand. The records cover continually a 1...
This study aims to investigate the changes in isotope ratios in foliage and soils of two Norway spruce (Picea abies [L.] Karst.) forests greatly differing in their atmospheric N deposition and climati...
Nitrate nitrogen (NO3-N) concentrations of stream water have been observed in the headwater catchments within Gunma Prefecture located in northwest of Metropolitan area Japan. Large differences of NO3...
High concentrations of CO2 in soil air affect subsurface water quality and weathering reactions; however, few simple methods have been proposed for the collection of soil air from deep soils. Therefor...
