Strong Changes in Soil Nutrient Stocks in Northern Forests Over Four Decades
Northern forests are currently taking up large quantities of carbon due to tree growth. Yet, it is not known how the stocks of soil nutrients have responded to this increase in biomass. Therefore, we analyzed thousands of forest soils in Sweden over the last four decades. Our results show that stocks and concentrations of plant‐available cations in the

Determining Exchangeable Base Cations in Forest Soils: A Comparison of Three Methods
ABSTRACT Background Accurately determining exchangeable base cations is critical for assessing base cation depletion in acid forest soils, where various extraction methods may yield different results. Aim The aim was to quantify differences in the effectiveness of BaCl2, NH4OAc (pH 7), and Cohex methods in extracting base cations from acid forest soils
