“…The ratio between current pool of base cations in tree biomass and the exchangeable base cation pool in the soil increased linearly with accumulated acidity load for counties with few soils with CaCO 3 influence or high clay content in the parent material. This is in agreement with data from experimental sites in Europe and North America, which show an increased base cation fraction with tree age (≈ standing volume), ultimately exceeding the exchangeable base cation pools in the soil (Watmough et al 2005 ; Richardson et al 2017 ). The county of Halland (N) is the only county that has more base cations in the trees than in the soils (BC biomass /BC soil ratio > 1).…”

The input of acidity to Swedish forest soils through forestry between 1955 and 2010 is compared with the acid input from atmospheric deposition. Depending on region, input of acidity from forestry was the minor part (25–45%) of the study period’s accumulated acid input but is now the dominating source (140–270 molc ha−1 year−1). The net uptake of cations due to the increase in standing forest biomass, ranged between 35 and 45% of the forestry related input of acidity while whole-tree harvesting, introduced in the late 1990s, contributed only marginally (< 2%). The geographical gradient in acid input is reflected in the proportion of acidified soils in Sweden but edaphic properties contribute to variations in acidification sensitivity. It is important to consider the acid input due to increases in standing forest biomass in acidification assessments since it is long-term and quantitatively important.

“…To explain these discrepancies, it has been hypothesized that the plant-available pool of nutrient cations may be larger than the exchangeable pool 20,[26][27][28] . Aluminium and iron (hydr)oxides as well as amorphous aluminosilicate structures, which are abundant in acidic soils, may develop a cationic exchange capacity and adsorb cations 29 .…”

The plant-available pools of calcium, magnesium and potassium are assumed to be stored in the soil as exchangeable cations adsorbed on the cation exchange complex. In numerous forest ecosystems, despite very low plant-available pools, elevated forest productivities are sustained. We hypothesize that trees access nutrient sources in the soil that are currently unaccounted by conventional soil analysis methods. We carried out an isotopic dilution assay to quantify the plant-available pools of calcium, magnesium and potassium and trace the soil phases that support these pools in 143 individual soil samples covering 3 climatic zones and 5 different soil types. For 81%, 87% and 90% of the soil samples (respectively for Ca, Mg and K), the plant-available pools measured by isotopic dilution were greater than the conventional exchangeable pool. This additional pool is most likely supported by secondary non-crystalline mineral phases in interaction with soil organic matter and represents in many cases (respectively 43%, 27% and 47% of the soil samples) a substantial amount of plant-available nutrient cations (50% greater than the conventional exchangeable pools) that is likely to play an essential role in the biogeochemical functioning of forest ecosystems, in particular when the resources of Ca, Mg and K are low.

“…Similarly logging residue extraction in forests impinges on the acid neutralising processes in soil and depletes base cation stocks (Ranius et al 2018). Additionally, soil disturbance may deplete micronutrients due to export from the soil profile through leaching (clear-felling) (Richardson et al 2017), enhanced chemical and microbial activity which accelerates mineralisation of organic matter and therefore nutrient release (tillage) (Shiwakoti et al 2019), or removal of the organic matter-rich top layer (soil scarification) (Reyes et al 2014).…”
