“…However, both phosphates and sulfates may undergo specific (Violante et al, 2005) sorption reactions in volcanic and/or andic soils (Camps Arbestain et al, 2001;Nanzyo et al, 1993;Sokolova and Alekseeva, 2008), onto variable charge surfaces associated with allophanic minerals and organometallic complexes of amorphous Al and Fe hydroxides (Mizota and Van Reeuwijk, 1989). These reactions depend on soil pH, the amount and nature of the sorbent (Alves and Lavorenti, 2004;Cichota et al, 2007), and the concentrations of competing ions (Rasiah et al, 2004;Violante et al, 2005;Zhang et al, 1996).…”

“…In line with this interpretation, Uchimiya et al (2010a) reported insignificant changes of soluble S concentrations in a soil amended with 5–20% of biochar derived from pecan shells. They observed an increase of soluble S concentration after mixing the soil with broiler‐derived biochar, but this increase was probably a consequence of the pronounced increase in pH associated with application of this type of biochar (Harward & Reisenauer, 1966; Nodvin et al , 1986; Sokolova & Alekseeva, 2008). In addition to pH, competitive sorption of biochar‐derived DOM can increase the solubility of S in soil (Kaiser & Zech, 1998; Sokolova & Alekseeva, 2008)…”

Biochar application has been suggested for reducing toxic levels of metals in contaminated soils and enhancing nutrient retention in agro‐ecosystems. We studied sorption of copper (Cu(II)) and sulphate‐sulphur (SO4‐S) to charcoal, gasification coke and flash‐pyrolysis biochar in order to relate sorption to char properties. Furthermore, we investigated the effect of composting of charcoal and gasification coke on sorptive properties. Langmuir sorption affinity coefficients for Cu(II) for non‐composted biochars increased in the order flash‐pyrolysis char < charcoal < gasification coke. The sorption capacity for Cu(II) of the chars decreased in the order gasification coke (629 mg kg−1) > flash‐pyrolysis char (196 mg kg−1) > charcoal (56 mg kg−1). Composting significantly increased the sorption affinity coefficient approximately by a factor of 5 for charcoal (up to 1.1 l mg−1) and by a factor of 3–4 for gasification coke (up to 3.2 l mg−1). Whereas Cu(II) sorption to gasification coke (composted or not) was largely irreversible, sorption to flash‐pyrolysis char and charcoal showed higher reversibility. Relationships between Cu(II) sorption and biochar properties such as cation exchange capacity, specific surface area or aromaticity suggest that sorption was largely determined by complexation with organic matter. Sorption of SO4‐S was negligible by non‐composted and composted biochars. Composted gasification coke might be suited to reducing toxic Cu(II) concentrations in contaminated soils. Composted charcoal can potentially improve Cu(II) retention in a plant available form in acidic, sandy soils with small organic matter contents. Transient effects of biochars on soil pH can over‐ride the influence of sorption to biochars on concentrations of trace elements in soil solution and their availability to plants.

“…Adsorption and desorption of sulfate from soil is related to soil solution pH (Sokolova and Alekseeva 2008) and organic C and their interactions. Our finding of lower sulfate adsorption at higher pH was consistent with many other studies that have found that minerals with positive surface charge were capable of adsorbing more anions at lower pH values (Courchesne and Hendershot 1990;Martinez et al 1998;Martinson and Alveteg 2004;Nodvin et al 1986).…”

Understanding the acid-base chemistry of soil and the soil processes related to the release or retention of sulfate and nitrate is important in order to predict watershed recovery from long-term acid deposition. Soils were sampled from the Noland Divide Watershed (NDW), a small, high-elevation watershed in the Great Smoky Mountains National Park receiving high rates of acid deposition over several decades. Soil samples were measured for chemical properties related to acidification and used to conduct sulfate adsorption and nitrogen (N) incubation experiments. Shallow soil was higher in acidic and basic ions than deeper soils, and the mean effective cation exchange capacity was 8.07, 5.06, and 3.57 cmol c kg −1 in the A, Bw, and Cb horizons, respectively. In all three soil horizons, the base saturation was equal to or below 7% and the ratio of Ca/Al was below 0.01, indicating that the NDW is very sensitive to acid deposition. Based on results from sulfate adsorption isotherms, the NDW has not reached its maximum sulfate adsorption saturation and is likely able to retain further additions of sulfate. Desorption of sulfate from NDW soils is expected if sulfate concentrations in soil solution drop below 50 μeq L −1 but is highly dependent on soil pH and organic carbon content. Total soil organic N was 500 times greater than inorganic N in the A soil horizon, and net N mineralization and nitrification remained constant during a 28-day incubation indicating a large reservoir of N substrate for soil microbes. Nitrogen experiment results suggest that nitrate export from the watershed is largely controlled by biological processes rather than by nitrate deposition flux. Soil data collected in this study contributes to our understanding of biogeochemical processes affecting the response of acid-impacted ecosystems such as the NDW to future changes in atmospheric deposition.
