“…1). The LOI contents recorded here are similar to those of other regionally representative AS soil studies (Nordmyr et al, 2006;Bärlund et al, 2004;Sohlenius and Öborn, 2004). The higher LOI of F1 than that of F3 was unexpected since the latter had a remarkably brownish subsoil, indicating organic matter of different composition and origin.…”

“…A 1.0 g aliquot of the topsoil splits (n = 11) was analyzed for the elements mentioned above after extraction in 10 mL 0.25 M hydroxylamine (NH 2 OH) digested at 90°C for 2 h followed by analysis with ICP-ES/MS. Iron oxides are found in large proportions in these soils (Åström, 1998;Sohlenius and Öborn, 2004), and they are well known sinks for mobile trace elements in surface environments (Kabata-Pendias, 2001). The metal fractions bound to Fe and Mn oxides are mobilized through dissolution of these with the strong 0.25 M hydroxylamine reductant (Hall, 1998;Filgueiras et al, 2002).…”

The purpose of this study was to investigate the influence of soil geochemistry on the concentrations of Ca, K, Mg, P, Co, Ni, Zn, Mn, Cu, and Fe in cabbage (Brassica oleracea L. var. capitata) grown on acid sulfate (AS) soils in Western Finland. A total of 11 topsoil (0-20 cm) and corresponding cabbage samples and three whole-soil profiles (≈ 0-260 cm) were collected on three agricultural fields. The concentrations of Co and Zn in cabbage were correlated with the NH 4 Acextractable (easily available) concentrations in the topsoil, indicating that the uptake of these elements in cabbage is largely governed by soil geochemistry. Yet, the concentrations of Co and Zn in cabbage were not in general elevated relative to that of Finnish average values, although some AS soils showed enriched concentrations of these metals in the soil and cabbage. Significant geochemical differences (e.g., oxidation depth, organic-matter and S content, pH) were observed among the studied AS soils, while, on the other hand, the concentrations of Ca, K, Mg, P, Ni, Mn, Cu, and Fe in cabbage were relatively similar. The hydroxylamine-extractable concentrations of these elements in the topsoil were not correlated to those in cabbage, suggesting that uptake is not governed by the oxide-bound fraction of these elements in the soil. Similarly, the easily available concentrations of Ca, P, Ni, Mn, Cu, and Fe in the topsoil were not correlated to those in cabbage, indicating that uptake is independent of the easily available concentrations in the soil. Hence, it is suggested that cabbage can regulate and thus optimize its concentrations of Ca, P, Ni, Mn, Cu, and Fe. Oxidation depth affected neither the easily available concentrations of Co, Ni, Zn, and Mn in the topsoil nor the concentrations in cabbage. However, the subsoil with a lower oxidation depth, which is to a smaller extent affected by leaching, may partly be enriched in these metals. Nevertheless, these showed no increased concentrations in cabbage. Based on these findings, it is suggested that the large amounts of metals mobilized in AS soils are easily lost to drains, subsequently contaminating nearby waterways and estuaries whereas they are only partly enriched in cabbage and other previously studied crops (oat).

“…The AS soils of the region are not rich in total concentration of metals but metals are extensively mobilised in the acidic environment created by oxidation of sulphides in non-calcareous soils (Sohlenius and Öborn 2004). From the agricultural point of view, many fields in the main AS soil area of Finland need more efficient drainage.…”

To abate the environmental problems caused by the severe acidity and high metal concentrations in rivers draining acid sulphate (AS) soils of Western Finland, control drainage (CD) and lime filter drainage (LFD), and their combination, were investigated. The effectiveness of these best management practices (BMP's) on drainage water quality was studied on plot scale in two locations. In Ilmajoki, where the sulphidic materials are more than 2 m below the soil surface, CD efficiently reduced the concentrations of sulphate, aluminium, manganese and iron concentrations and to some extent also increased the pH of the drainage waters. LFD, in contrast, effectively reduced the drainage water acidity and raised the pH level. Decrease of the groundwater level owing to strong evapotranspiration in summer could, however, not be properly prevented by CD. In Mustasaari where sulphidic materials were as shallow as 1 m below soil surface, the positive effects of LFD recognised in Ilmajoki were hardly seen. This shows, that the tested BMP's work properly, and can thus be recommended, for intensively artificially drained AS soils like in Ilmajoki where most of the acidity has already been transported to watercourses. LFD can, however, not be recommended for as yet poorly leached and thus particularly problematic AS soils like in Mustasaari. This is, of course, a drawback of the tested BMP, as it is not effective for the soils which would need it most. The field data were tentatively utilised to test the performance of the HAPSU (Ionic Flow Model for Acid Sulphate Soils) simulation model developed to estimate the loads of harmful substances from AS soils.

“…The mean value of the EC was 0.072 dS/m which indicates non-saline conditions according to [60]. With the range of 0.068 -0.074 dS/m among the four study areas, these findings indicate thatthere is no major difference in cumulative salt accumulation among the study areas.…”
