“…To grow blueberry at sites with a higher initial soil pH, elemental sulfur (S o ), which oxidizes to sulfuric acid by chemotrophic soil bacteria such as Thiobacillius species, is often mixed into soil before planting (Chapman, 1990;Germida and Janzen, 1993). In many soils, large amounts of S o (>1500 kg · ha -1 ) are needed for the process, and in some cases, such as in soils with high amounts of calcium carbonate, S o acidification is unfeasible (Horneck et al, 2006;Modaihsh et al, 1989;Neilsen et al, 1993). Soil incorporation of S o is also limited after planting because blueberry has a fine, shallow root system (<0.3-m deep) that is easily damaged by cultivation (Bryla and Strik, 2007).…”

“…Modaihsh et al [17] also reported that the decrease in soil pH upon S-addition was higher with lower CaCO 3 content. [8,[16][17][18] The high correlation of pH, EC, and SO 4 confirms that any of these variables could be a useful measurement of S 0 oxidation under calcareous soil conditions. Lindemann et al [8] reported that no improvement was observed in studies in New Mexico.…”

“…[5,8,9,13,14] In calcareous soils, the sulfuric acid formed from oxidation of the applied elemental S is buffered by base constituents, mainly carbonates. Neilsen et al, [16] studying the oxidation of elemental S and acidulation of calcareous soils, reported that the magnitude of pH decreased in response to added S, varied inversely with initial CaCO 3 content. However, when the application rates of acid exceed the acid titratable basicity, soil pH would remain in the extremely acid range because the readily reactive base has been neutralized.…”

The use of elemental sulfur (S) is of special interest in Iran since most soils are calcareous and elemental S, as a byproduct of the petroleum industries, is readily available. Recently, the National Petrochemical Company (NPC) of Iran, has produced an agricultural sulfur (A.S.) that contains 90% pure sulfur and 10% bentonite. As the production of this compound is in the experimental stage, relatively little information is available on its disintegration and subsequent oxidation to sulfate in the salt-affected calcareous soils. The present study was initiated to improve ORDER REPRINTS the understanding of the disintegration rate of A.S. in soil, based on the determination of changes in some of the soil chemical properties. Six soil samples were collected from different sites of a dry region of Fars Province of southern Iran and A.S., produced by the NPC of Iran, was thoroughly mixed with 2 kg of soil at the equivalent rates of 0, 2, 4, and 6 t ha À1 . The samples were incubated under room temperature and moisture content of field capacity for 8 weeks, and pH and EC values as well as sulfate, total nitrogen (N), phosphorus (P), iron (Fe), manganese (Mn), zinc (Zn), and copper (Cu) concentrations were determined. The results showed that the disintegration rate was very low, and only 1.5, 2.3, and 2.0% of the applied A.S. levels (i.e., 2, 4, and 6 t ha À1 ) were oxidized to sulfate, respectively. The results of pH and EC values were well accorded with those of sulfate contents, and an increase in A.S. level, resulted in no significant changes in the nutritional constituents (except Mn) of the tested soils.

“…Elemental sulfur (S) is a natural material and can be applied to improve availability of nutrients and decline their deficiencies in calcareous and alkaline soils (Neilsen et al, 1993 andManesh et al, 2013). Sulphur has a vital role in activation of photosynthesis process, carbohydrate metabolism and certain enzyme systems in plants, and can enhance seed and oil yields, and protein contents (Chatterjee et al, 1992, Abdallah et al, 2010and Yadav et al, 2013 It is considered as an important nutrient in the synthesis of some benefit compounds such as chlorophyll in soybean leaves and vitamins (biotin and thiamine) and amino acids, including cystine, cysteine and methionine in its seeds.…”

A FIELD experiment was conducted during the summer season of 2013 in the farm of Faculty of Agriculture, Benha University, Egypt. Sixteen treatments with three replicates were performed and resulted from the combination of four rates of the elemental sulfur (S0=zero, S1=119, S2=238 and S3=357 kg S ha-1) and four rates of P (P0=0, P1=238, P2=476 and P3=714 kg superphosphate ha-1). Application of S at all used P rates increased branch and pod numbers, nutrients concentrations, and protein and oil contents of soybean. The highest values of the above-mentioned parameters were found at addition of 357 kg S ha-1 in the presence of 714 kg superphosphate ha-1 , which were statistically similar to those at 238 kg S ha-1 with 476 kg superphosphate ha-1. Straw and seed yields of soybean showed the same performance under 238 kg S ha-1 and 357 kg S ha-1 in the presence of all applied doses of superphosphate. So, application of 238 kg S ha-1 and 476 kg superphosphate ha-1 could be highly recommended to increase the yield of soybean. Soil properties also markedly affected by addition of the elemental S. Soil pH decreased from 7.53 at S0P0 (control) to 7.12 at S3P3 treatment. Available P showed another pattern, its highest values were 44.22 and 45.65 mg kg-1 as results of S2P3 and S3P3 additions and without significant differences between them. The current study confirmed the positive role of the elemental S in improving both soil fertility and soybean production in the chosen clayey soil under field conditions.
