“…S-application significantly increased available Mn (DTPA extractable Mn) in calcareous soils at all rates of S-application (Table 3). Highest values of available Mn were recorded in the surface soil (0-10cm) and after 3-6 weeks of incubation and were not associated with the lowest pH values suggesting that the increase in Mn may be attributed to the reducing effect of sulphur rather than to the decrease in pH (Garey and Barber, 1952;Tisdale and Bertramson, 1949). Table 4 shows that S-application increased available Mn in the surface (0--10cm) of the three soils in the order: Dirab loamy sand ,~ Kharge sandy < Qasseem sandy loam.…”

Elemental sulphur was added to three calcareous soils varying in texture, CaCO 3 content, native phosphorus and micronutrient content at a rate of 0.5, 1.5 and 3.0% (w/w). The experiment was carried in soil columns which were intermittentantly leached and incubated at 30~ for 3,6,9, and 18 weeks. Sulphur applied at a rate of 0.5% significantly decreased the pH and increased the EC and the soluble sulphate content in all three soils and their leachates with slight differences among soils. Sulphur application generally increased 0.5M NaHCO 3 extractable P and DTPA extractable Mn, slightly increased DTPA extractable Fe and Cu but had no significant effect on DTPA extractable Zn. The decrease in soil pH and the increase in DTPA extractable P,Mn,Fe, and Cu upon S-addition were higher with lower CaCO3 content, lower CaCO3/clay ratio and with higher extractable content of these nutrients. Most chemical changes occurred at rate of 0.5% sulphur within 9 weeks of incubation and were largely confined to the soil surface where sulphur was mixed with soil. DTPA extractable Fe and Cu, however, were affected only at higher rates of S-application.

“…Both Mn(IV) and Fe(III) nonenzymatically oxidize sulfide (Table 1, reactions 1 and 2) but only to the redox level of S0 (5,16). Thus, it has been suspected that the production of sulfate in Mn(IV)-amended marine sediments (1, 21), as well as the production of Mn(II) and sulfate in soils amended with S0 (38,40), is the result of microorganisms catalyzing the oxidation of So to sulfate with Mn(IV) serving as the electron acceptor (Table 1, reaction 3). The finding that metabolic inhibitors inhibit Mn(IV)-dependent sulfate production in marine sediments (1) further supports this possibility.…”

Sulfate reducers and related organisms which had previously been found to reduce Fe(III) with H2 or organic electron donors oxidized So to sulfate when Mn(IV) was provided as an electron acceptor. Organisms catalyzing this reaction in washed cell suspensions included Desulfovibrio desulfuricans, Desulfomicrobium baculatum, Desulfobacterium autotrophicum, Desulfuromonas acetoxidans, and Geobacter metallireducens. These organisms produced little or no sulfate from S with Fe(III) as a potential electron acceptor or in the absence of an electron acceptor. In detailed studies with Desulfovibrio desu(/i4ricans, the stoichiometry of sulfate and Mn(II) production was consistent with the reaction S + 3 MnO2 + 4H ,->SO42-+ 3Mn(II) + 2H20. None of the organisms evaluated could be grown with S as the sole electron donor and Mn(IV) as the electron acceptor. In contrast to the other sulfate reducers evaluated, Desulfobulbus propionicus produced sulfate from So in the absence of an electron acceptor and Fe(III) oxide stimulated sulfate production. Sulfide also accumulated in the absence of Mn(IV) or Fe(III). The stoichiometry of sulfate and sulfide production indicated that Desulfobulbus propionicus disproportionates S as follows: 45 + 4H20-,SO42-+ 3HS-+ 5 HW. Growth of Desulfobulbus propionicus with So as the electron donor and Fe(III) as a sulfide sink and/or electron acceptor was very slow. The S oxidation coupled to Mn(IV) reduction described here provides a potential explanation for the Mn(IV)-dependent sulfate production that previous studies have observed in anoxic marine sediments.

“…It is well known that soil acidification by elemental S results in increased uptake of Mn by plants (Garey and Barber, 1952;Hassan and Olson, 1966;Procopiou et al, 1976). It has been suggested that a major effect of S on Mn availability is in a decrease of the easily reducible Mn in soil as S is oxidized rather than soil acidification directly (Tisdale and Bertramson, 1959). Organic complexing of Cu and Fe in soils appears to result in their solubility being less pH dependent than that of Mn and Al (Haynes and Swift, 1985).…”

With the increasing cultivation of acid-loving plants such as blueberries, the artificial acidification of soils is frequently required. This research was conducted to determine the application rates of elemental sulfur (S) required in the soil acidification for blueberry cultivation. Laboratory incubation experiment was conducted to acidify three arable soils (pH 6-7) of different texture to pH 4.5-5.0 by the addition of varying amounts of elemental S. All rates of elemental S addition reduced soil pH, although the efficacy of acidification was related to the application rate and soil characteristics. pH reduction was slow in sandy loam soil, and the final equilibrium pH was obtained after 60, 43, and 30 days of incubation in sandy loam, loam, and silty clay, respectively. Although the final pHs obtained after 93 days of incubation were not significantly different among the three soils, the equilibrium pH was relatively higher in soil of higher clay content in the application rates of 1.5-2.0 g S kg -1 soil. The estimated amounts of elemental S required in lowering pH to 4.5-5.0 were 0.59-1.01, 0.67-1.03, and 0.53-0.88 g S kg -1 for sandy loam, loam, and silty clay, respectively. The lowest estimated amount of elemental S in the acidification of silty clay soil was attributable to the low organic matter content. For clay soils containing optimum level of organic matter, the application rates of elemental S should be much higher than those values estimated in this research. Soil acidification did not significantly increase the available concentrations of Ca, Mg and K. Extractable Cu and Zn was not greatly affected by the acidification, but extractable Fe, Mn, and Al in the acidified soils were higher than those found in non-acidified soils. Such increases in solubility are attributable to the dissolution of oxides and hydroxides of the elements.
