Sulfur Fertilization

This study investigated the impact of repeated application of S° fertilizer on microbial and biochemical characteristics of two Grey Luvisolic soils. The Waitville pasture plots received Agri-Sul at a rate of 22 or 44 kg S° ha−1 yr−1 for 5 yr, whereas the Loon River canola-summerfallow plots received single or double applications of Flow-able Sulfur (50 kg S° ha−1) or Agri-Sul (100 kg S° ha−1). Application of S° fertilizer significantly decreased the pH in both soils. Organic C declined in S°-treated plots of the Waitville soil, and there was a narrowing of C:N:S ratios in both soils. Application of S° fertilizer significantly increased the total S, HI-S and sulfate sulfur levels of both soils. There was a 29–45% and 2–51% decline in microbial biomass carbon content due to S° fertilizer application in Waitville and Loon River soils, respectively. Repeated application of S° also resulted in a decline in respiration, dehydrogenase, urease, alkaline phosphatase and arylsulfatase activities, along with populations of protozoa, algae and nitrifiers in both soils. Significant correlations observed among related characteristics further emphasized the treatment effects. These results indicate that the impact of repeated application of S° fertilizer on microbial biomass and activity should be considered when recommending S° as a fertilizer for sulfur-deficient soils.

Sulfur Fertilizers

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.

Sulfur Fertilization

A three-year field experiment was conducted in North-East Poland. Each year three sulfur fertilization rates in the form of sulphate (S-SO<sub>4</sub><sup>2&ndash;</sup>) and pure (S&ndash;S<sup>0</sup>) sulfur were applied: 40, 80, and 120 kg/ha. After the third year of the study, the application of sulfate and elemental sulfur decreased the zinc content of 0&ndash;40 and 40&ndash;80 cm soil layers, as compared with soil sampled before the experiment. Over the entire experimental period, sulfur fertilization had no significant effect on changes in the natural copper content of soil at a depth of 0&ndash;40 and 40&ndash;80 cm. Manganese concentrations remained at a similar level at a soil depth of 0&ndash;40 cm. The manganese content of the 40&ndash;80 cm soil layer was substantially lower than in the 0&ndash;40 cm horizon. An insignificant increase in the lead content of soil was observed. The applied doses of sulfate and elemental sulfur led to an increase in the cadmium content of soil depth of 0&ndash;40 cm. Sulfur fertilization contributed to a decrease in the nickel content of soil. The applied doses of sulfate and elemental sulfur exerted a stronger effect in the 0&ndash;40 cm soil layer than in the 40&ndash;80 cm horizon. &nbsp;

Sulfur Fertilization

Effects of elemental sulfur fertilization on sulfur-oxidizing populations, rhodanese activity, total sulfur content and sulfur oxidation rates in the 0- to 15-cm zone of two Grey Luvisolic soils were assessed. Heterotrophic sulfur oxidizers were the most abundant sulfur oxidizers detected in both soils. Elemental sulfur fertilization caused an increase in populations of autotrophic thiosulfate-oxidizing micro-organisms, and a threefold increase in rhodanese and sulfur-oxidizing activity in a Waitville soil. In contrast, sulfur fertilization did not stimulate autotrophic thiosulfate oxidizers in a Loon River soil and the greatest increase in rhodanese and sulfur oxidation rates was only 31%. The response to sulfur application was biphasic however, and subsequent additions of sulfur fertilizer resulted in a decline in oxidation rates. Total sulfur content of sulfur-treated soils indicated that most of the sulfur applied was still present in the sampled zone. These results imply that prediction of sulfate release and fertilizer efficiency will be difficult to assess. Key words: Sulfur (elemental), S-oxidation, oxidation rates, rhodanese, sulfur-oxidizing micro-organisms

S Oxidation

Heterotrophic and autotrophic sulfur-oxidizing populations in 35 Saskatchewan agricultural soils were enumerated. These populations included heterotrophs that produce thiosulfate and or sulfate during elemental sulfur (S°) oxidation, heterotrophic thiosulfate oxidizers, and autotrophic thiosulfate oxidizers. Populations of Thiobacillus thiooxidans and T. ferrooxidans were not detected in any of the soils tested. Heterotrophs that oxidized S° to thiosulfate as the major oxyanion were the most abundant oxidizers enumerated (107–108 cells g−1) and were found in all soils. Autotrophic thiosulfate-oxidizers were detected in 10 of the soils surveyed. Heterotrophic S° and thiosulfate-oxidizing populations exhibited positive trends with soil pH, total-S, hydriodic reducible-S, and clay content, whereas populations of autotrophic thiosulfate oxidizers were negatively correlated with these factors and positively related to sand content and increasing C:S ratios. In soils containing autotrophic thiosulfate oxidizers the amount of thiosulfate relative to sulfate detected was reduced although no effect on S° oxidation rate was detected. Amendment of 15 selected agricultural soils with 0.5% S° significantly reduced total heterotrophic populations, whereas autotrophic thiosulfate oxidizers increased from undetectable levels to 104 cells g−1. Therefore most Saskatchewan soils contain abundant populations of heterotrophic S° oxidizers, and populations of autotrophs that respond to S° applications.

Scanning Electron Microscope Study

There are two strains of bacteria viz. Thiobacillus thiooxidansand Thiobacillus ferrooxidanswidely mentioned to play an important role in the leaching process of low-grade ores. Another strain used in this study is a thermophile and is designated Caldariella .These microorganisms are acidophilic chemosynthetic aerobic autotrophs and are capable of oxidizing many metal sulfides and elemental sulfur to sulfates and Fe2+ to Fe3+. The necessity of physical contact or attachment by bacteria to mineral surfaces during oxidation reaction has not been fairly established so far. Temple and Koehler reported that during oxidation of marcasite T. thiooxidanswere found concentrated on mineral surface. Schaeffer, et al. demonstrated that physical contact or attachment is essential for oxidation of sulfur.
