“…In contrast, Lettl et al, (1981) found a linear relationship between S oxidation and S concentration up to 1% (w/w) though in their experiments only 15% of the sylphur was oxidized. Janzen and Bettany (1987a) made a similar finding but in their case only 1.5% of the sulphur added was oxidized over the experimental period.…”

The rate of oxidation of micronized elemental sulphur in three soils was measured over a range of temperatures between 2 and 20~ Temperature had a marked effect with a Q10 (temperature coefficient) between 1.9-3.1. The period for 50% oxidation varied between 6-10 days at 20~ to between 36-42 days at 2~ All the oxidation curves showed an initial lag. At 20~ the oxidation rate was four times that of flowers of sulphur and was related to the smaller particle size. Additives (wetting and dispersing agents) in the commercial micronized sulphur preparation used ('Thiovit') were inhibitory at high concentrations but stimulatory at low concentrations. The significance to field conditions is discussed.

“…The S-shaped (sigmoidal) oxidation curve has been noted previously (Janzen and Bettany, 1986) and several other studies have found a pronounced lag phase (Gleen and Quastel, 1953;Lettl et al, 1981;Lipman et al, 1916;Wainwright et al, 1986). The reasons for this lag period are not clear.…”

“…Transformation and fate of applied fertilizer is shaped by its chemical form, solubility in soil, interaction with minerals, pH, organic matter, and the presence of other anions. There is a growing demand for elemental sulfur fertilizers due to high concentration of nutrient, negligible leaching losses and residual effect observed in subsequent growing seasons, and also due to economic aspects since elemental sulfur application and transport costs are low [80,81].…”

There is a potential for using sulfur waste in agriculture. The main objective of this study was to design a granular fertilizer based on waste elemental sulfur. Humic acids and halloysite were used to improve the properties and their influence on soil properties. This is the first report on the use of proposed materials for fertilizer production. The following granular fertilizers were prepared (the percentage share of component weight is given in brackets): fertilizer A (waste sulfur (95%) + halloysite (5%)), fertilizer B (waste sulfur (81%) + halloysite (5%) + humic acids (14%)), fertilizer C (waste sulfur (50%) + halloysite (50%)) and fertilizer D (waste sulfur (46%) + halloysite (46%) + humic acids (8%)). Basic properties of the obtained granulates were determined. Furthermore, the effect of the addition of the prepared fertilizers on soil pH, electrolytic conductivity, and sulfate content was examined in a 90-day incubation experiment. Enrichment with humic acids and the higher amount of halloysite increased the fertilizer properties (especially the share of larger granules and bulk density). In addition, it stabilized soil pH and increased the sulfur content (extracted with 0.01 mol·L−1 CaCl2 and Mehlich 3) in the soil.

“…. 15 The oxidation of ES occurs under aerobic conditions and is an acid-producing process. Many microorganisms can oxidize ES (S 0 ) to SO 4 2− , but the most efficient are the chemoautotrophic bacteria Acidithiobacillus thiooxidans and Acidithiobacillus ferrooxidans.…”

Acidification by oxidation of elemental sulfur (ES) can solubilize ZnO, providing slow release of both sulfur (S) and zinc (Zn) in soil. For this study, a new granular fertilizer with ES and ZnO was produced and evaluated. The effect of incorporating microorganisms or a carbon source in the granule was also evaluated. Four granulated ES-Zn fertilizers with and without S-oxidizing microorganisms, a commercial ES pastille, ZnSO, and ZnO were applied to the center of Petri dishes containing two contrasting pH soils. Soil pH, CaCl-extractable S and Zn, and remaining ES were evaluated at 30 and 60 days in two soil sections (0-5 and 5-9 mm from the fertilizer application site). A visualization test was performed to evaluate Zn diffusion over time. A significant pH decrease was observed in the acidic soil for all ES-Zn fertilizer treatments and in the alkaline soil for the Acidithiobacillus thiooxidans-inoculated treatment only. In agreement with Zn visualization tests, extractable-Zn concentrations were higher from the point of application in the acidic (62.9 mg dm) compared to the alkaline soil (5.5 mg dm). Elemental S oxidation was greater in the acidic soil (20.9%) than slightly alkaline soil (12%). The ES-Zn granular fertilizers increased S and Zn concentrations in soil and can provide a strategically slow release of nutrients to the soil.
