… However, there are concerns that removal of biomass will lead to decreased base cation concentrations in the soils and acidification of streams. In order to find in which types of landscape removal of branches and tops could have such negative effects, this study aims to analyse …
what are the soil requirements”
… also analyzed for texture, effective cation exchange capacity, exchangeable base cations, Al, Fe and Mn, effective base saturation, exchangeable acidity and oxalate and dithionite extractable Al, Fe and Mn. The results showed that the soils had very low pH, generally below 4.5 …
… or/and the MAGIC-library. These models require a complete analysis of base cations (Ca2+, Mg2+, Na+, K+) and anions (SO42-, Cl-, NO3-). Instead, the buffer capacity was calculated from CBALK, which means that the alkalnity at pH=5,6 and TOC were used to estimate the buffer …
Samband mellan sänkningsnivåer och vattenkemi i sjöar på sulfidrika sedimentjordar
… Water samples were then analyzed for TOC, pH, conductivity, anions, base cations, alkalinity, acidity, sulfate, Al, Cd, Fe, Mn, Cu, Zn and Pb. These parameters were then compared statistically using regression analysis and t-tests. The results show that no gradient was …
biobränslets och askans innehåll av tungmetaller relaterat till markernas geokemi
… Ash from the combustion of biofuels contains many valuable nutrients and base cations. The Swedish Forest Agency recommends that ash should be recycled to clearings where biofuels have been removed, to avoid future impoverishment of Swedish woodlands. In Jämtland, in northern …
