Sulphate Sulphur

The current investigation was conducted to study the fractions of sulphur in nine districts of low and mid hills of Himachal Pradesh. For this purpose 31 representative soil sampling sites were selected from nine districts and the soil samples were analyzed for physicochemical properties and different fractions of sulphur (water soluble sulphur, exchangeable sulphur, available sulphur, non-sulphate sulphur, organic sulphur and total sulphur). The results indicated that the total sulphur in soils varied from 98.2 to 470.1 mg kg-1 in surface soil (0-15 cm) and 67.2 to 370.7 mg kg-1 in sub-surface layer (15-60 cm). The organic sulphur varied from 80.5 to 401.1 mg kg-1 in surface and 44 to 306.1 mg kg-1 in sub-surface layer. The water soluble sulphur, exchangeable sulphur, available sulphur and non-sulphate sulphur varied from 1.7 to 9.2, 2.7 to 18.4, 4.5 to 27.6 and 10.2 to 58.9 mg kg-1 respectively in surface soil and 0.5 to 5.4, 1 to 17.7, 3.7 to 23.5 and 12.5 to 50.2 mg kg-1, respectively in sub-surface soil. It was observed during course of study that with increase in the soil depth the content of different fractions of sulphur decreased. These soils had the major part of their total sulphur content in organic form followed by non-sulphate sulphur, available sulphur, exchangeable sulphur and water soluble sulphur. It can be concluded that the soil texture and organic carbon content played a major role in determining the quantity of different fractions of sulphur in these soils.

To determine whether sulphate addition to sulphur-deficient soils affects mineralization of organic sulphur, an experiment was conducted in undrained pots with five soils of differing properties. Initial and final extractable soil sulphate (water-soluble and adsorbed), and sulphur taken up by Phalaris tuberosa L., were measured. Where plants were grown, mobilization of the organic sulphur occurred at the nil, 4 p.p.m., 12 p.p.m., and 36 p.p.m. levels of sulphate sulphur addition in four out of the five soils. In the fifth soil, a lateritic krasnozem, only at the nil and 4 p.p.m. levels was there any net release of sulphate. All five soils immobilized added sulphate at the 108 p.p.m. level. In the absence of plants, with one exception, no net mineralization of organic sulphur occurred following additions of sulphate. In the pots without added sulphate there was slight mineralization (less than under plants) in all soils but the lateritic krasnozem. The modifying effect of growing plants is obviously of great significance in the cycling of sulphur in soil. The relative intensity of immobilization and mineralization was affected by the presence of growing plants. This effect was probably due to the activities of rhizosphere microorganisms.

Abstract Soil organic carbon is one of the most important soil components, which acts as a sink for atmospheric CO2. This study focuses on the effect of different methods of organic matter application on the soil organic carbon sequestration in a 4-month experiment under controlled greenhouse conditions. Three rates of straw residue and farmyard manure were added to uncultivated and cropland soils. Two treatments of straw residue and farmyard manure incorporation were used into: a soil surface layer and 0-20 cm soil depth. The result showed that the application of organic matter, especially the farmyard manure incorporation led to a significant increase in the final soil organic carbon content. Higher amounts of soil organic carbon were stored in the cropland soil than in the uncultivated soil. On average, the soil surface layer treatment caused a higher sequestration of soil organic carbon compared to the whole soil depth treatment. If higher rates of organic matter were added to the soils, lower carbon sequestration was observed and vice versa. The result indicated that the carbon sequestration ranged farmyardmanure > strawresidue and cropland soil > uncultivated soil. The findings of this research revealed the necessity of paying more attention to the role of organic residue management in carbon sequestration and prevention of increasing global warming.

1. Three varieties of giant rape, two broad leaved Essex rapes, Hungry Gap Kale and Rape-Kale, were grown at two centres in mid-Wales. They were sampled in the early winter period and the samples divided into separate leaf and stem samples. These samples were used to calculate leaf to stem ratios on a green and dry-matter basis.2. The levels of the proximate constituents, silica, calcium, magnesium, phosphorus, sodium, potassium, chlorine, total sulphur, sulphate sulphur and ‘organic’ sulphur were determined in the dried samples. Whole plant values were calculated from the leaf and stem values with the appropriate leaf to stem ratios.3. The leaf values for ether extract, crude protein, silica-free ash, silica, calcium, phosphorus, magnesium, chlorine, total sulphur and ‘organic’ sulphur are higher than the corresponding stem values. For dry matter, crude fibre, nitrogen-free extractives and sodium the reverse is found, whilst for sulphate sulphur there is no definite distribution.4. There are no significant differences in composition between the main groups of varieties, and the rape-type kales are very similar to the other rapes in this respect.

Short And Long Term

The knowledge of different sulphur (S) forms and their relationship with soil properties is of much relevance in assessing the short- and long-term availability of the nutrients to crops and in formulating sound fertilizer recommendations. For this purpose one hundred and one representative soil samples were collected from the study area and analyzed for various physicochemical properties and forms of sulphur (water soluble, exchangeable, available, organic, non-sulphate and total S) using standard methods. The different forms of sulphur viz., water soluble, exchangeable, available, organic, non-sulphate and total sulphur ranged from 1.1 to 7.0, 1.9 to 10.9, 3.1 to 21.1, 75.9 to 316.1, 8.0 to 41.5 and 75.5 to 372.5 mg kg-1, respectively in soils of Outer Himalayas under different land uses. The content of different forms of sulphur present in these soils were in the order of total sulphur, organic sulphur, non-sulphate sulphur, available sulphur, exchangeable sulphur and water soluble sulphur. All the forms of S correlated positively and significantly with organic carbon and clay content of soils. A negative and significant relationship was also observed between all forms of sulphur and sand content of soils. In the present study, it was also found that all forms of S present in soils were significantly and positively correlated with each other. The knowledge regarding different forms of S in soils and their availability controlled by different soil properties will be helpful for its management to optimize crop yields in the Outer Himalayas of Himachal Pradesh.

The chemical desulphurisation from an Indonesian high sulphur sub-bituminous Banjarmasin Haji Ali-Aliansar coal was investigated using the peroxyacetic acid (PAA), a mild oxidising agent. A mixture of hydrogen peroxide:acetic acid (i.e. 30:70 by volume ratio with 6% of hydrogen peroxide concentration) at 50°C of reaction temperature is capable of reducing the total sulphur content in the coal from 3.46% to 1.29% by weight, corresponding to the removal of up to ca. 72% of the total sulphur; both the inorganic (mainly pyrite) and organic sulphur forms, and approximately 10 to 44% of ashes in the coal. The simultaneous removal of both inorganic and organic sulphur forms was measured with respect to reagent volume mixed ratio, reaction temperature and hydrogen peroxide concentrations. The success of desulphurisation was measured by the reduction of the total sulphur content of the desulphurised product, its S/ C atomic ratios and ash yields of the treated coal. In general, all inorganic and some of the organic sulphur could be removed from the coal using mild conditions without severely affecting the coal microstructure as observed via the Scanning Electron Microscope with Energy Dispersive X-ray (SEM-EDX)  which supplied the coal sample.

Aiming to study effects of soil depth and rivers slop on total boron concentration inMiddle Euphrates River Reion that represent in the sedimentary plain, soil pedon samples of cultivated territory that adjacent to rivers were taken. Theseregions are located in provinces of Karbala, Babylon, Najaf, Diwaniyah, and Al-Muthana. Ten soil pedon were taken of soils that adjacent to the main Euphrates River, the Al-Hilaa, and the AL-Daghara Rivers in these provinces. Soil pedon of soils that on the banks or close to the main Euphrates River were taken of counties of Twarije, Kufa, Gamas, and Al-Samawa. In the same way, soil pedon of Missaib, Hashmiah, Diwaniyah, and Rumitha are adjacent to the Hilla River and soil pedon of Al-Daghara and Affak belongs to the area of Al-Daghara River. Results show a reduction in total boron concentration for all of the tested soil pedon directly related with the depth. Aggregate boron concentration values are the highest at the surface layer and reduce as going depth except for soils of Al-Samawa and Al-Rumitha. Total boron concentration values are fluctuated between 1.033 mg. kg-1 and 14.658 mg. kg-1 in all of the studied soils. the results showed too the total boron values are not conducted with the tourmaline mineral percent in all sites
