“…Mean pH, based on the average of the pH data (Baker et al, 1981), and Ca concentrations for the upper forest floor (Oi + Oe) and the humus/mineral soil transition layer (Oa + A) are given in Table I for 1990 and 1991. Both pH and Ca concentrations were greater (P _<0.01) in the upper forest floor of limed than reference subcatchments during both years.…”

Abstract. Effects of watershed liming on the biomass and tissue chemistry of planted Picea rubens Sarg. (red spruce) seedlings were investigated for two growing seasons after two subcatchments in a forested Adirondack, New York (U.S.A.) watershed were limed aerially with 6.89 t ha-t of calcitic limestone (CaCO3). Picea rubens has been the focus of numerous atmospheric deposition research studies, but less well investigated for responses to amelioration. Picea rubens seedlings were planted in limed and reference subcatchments and harvested the first and second growing season after liming to measure total, foliar, and stem (i.e., branch) biomass, and concentrations of Ca, Mg, K, AI, Na, and P in the annual growth increment of foliage and branches. In the second year after liming, both foliage and stem biomass of seedlings from reference plots were at least 50% greater than seedling biomass from limed plots. Seedlings in limed areas had significantly greater foliar concentrations of Mg and P in the first year after liming, but not in the second year. Foliar Ca was not significantly different in limed than reference seedlings. Foliar A1 concentrations were greater in reference than limed seedlings, but still below documented toxicity levels. Stem concentrations of Mg, K, and P in seedlings from limed areas decreased significantly between the first and second growing season after liming, while reference seedling stem concentrations either increased or declined only slightly. Correlations among foliar nutrients and foliar biomass from limed plots were negative and suggest an inverse dilution effect. Foliar A1 concentrations were negatively correlated with Ca, Mg, K, and P in seedlings from reference plots, but positively correlated in limed plots. The adverse response of P. rubens seedlings to lime may reflect changes in nutrient availability associated with changes in soil pH.

“…The total number of composite surface samples was 66 (one per site per year). Compositing has been shown not to diminish sampling efficacy in accounting for pH spatial variability (BAKER, et al 1981). Surface bulk density samples were taken from each land parcel with a core sampler, using a slide hammer.…”

Short-term acidification detection in soils along the northern Dráva floodplain (SW Hungary) by means of Acid Neutralising Capacity (ANC) analysis

Various methods can be used for soil acidification monitoring, which can be useful towards remediation or preventing environmental degradation. It has been demonstrated that acidification can be made evident over the span of a few years, with proper monitoring. However, a reliance on pH as a main indicator can lead to detection inadequacies, especially where soils are relatively well buffered against acidity and acid deposition is negligible. A technique employing acid-neutralising capacity (ANC) derivation was applied to cultivated and uncultivated Alluvial Meadow soils to find out whether ANC data could prove effective in determining the occurrence and degree of acidification. Sampling and lab work were carried out between 2009 and 2010 on 33 sites under various land uses. Unlike pH, ANC, soil organic matter (SOM), and cation exchange capacity (CEC) decreased significantly. ANC analysis appears to be effective in detecting acidification trends over short periods and, in contrast to previous studies, under ostensibly unremarkable conditions.
