Soil sulphur fractions and their relationship with soil properties and rice (Oryza sativaL.) yield under long-term integrated nutrient management in an acid Alfisol

Sulphur Fractionation Studies in Soils of Long Term Fertilizer Experiment under Finger Millet – Maize Cropping Sequence

“…Increase in inorganic sulphur content was found to be minimum in treatment T 9 (15.75 to 17.32 mg kg -1 ) which received S free phosphatic fertilizer (DAP) followed by T 7 (15.72 to 18.28 mg kg -1 ) which received only 100 % N and control (15.76 to 19.68 mg kg -1 ). Addition of only nitrogenous fertilizer to soil favoured solubilisation of the sulphate that was co-precipitated with CaCO 3 and the solubilized sulphate was partly transformed into soluble organic form (Hu et al, 2005).The results were in conformity with the observations recorded by Sharma et al, (2014), who showed that zero fertilization led to decline in the levels of all S forms, while application of sulphur containing fertilizer and organics increased it over control. This might be due to release of sulphur from inorganic and organic S sources applied to different treatments and the treatments which recorded lower inorganic sulphur was due to continuous crop removal without addition of any S source and conversion of inorganic form of sulphur to sulphate sulphur.…”

Assess the Sulphur Fractions in Soil as Affected by Soil Test Based Nutrient Application

“…The increase of heat soluble S with increased levels of NPK + FYM was also similarly reported by Rashid et al [23], Patel et al [24], Dutta et al [25], Upinder [26] and Sharma et al [22] in their studies. The increase of organic S with NPK and FYM were also reported by Tripathi et al [27], Gosh et al [28], Jat and Yadav [29], Rai et al [30], Sharma et al [22], Saren et al [31]. The increase of total S with application of NPK fertilizers with FYM were also reported by Bhatnagar et al [32], Rai et al [30], Dutta et al [25] and Saren et al [31].…”

“…Similar results were obtained by Sachidanand et al [13], Rahman et al [14], Kumar et al [15], Ram et al [16], Shivay et al [17], Sharma and Subehia [18], Sarker et al [19], Chesti et al [20] and Warjri et al [21]. Sharma et al [22], reported higher water-soluble sulphur content in 100% NPK application. The increase of heat soluble S with increased levels of NPK + FYM was also similarly reported by Rashid et al [23], Patel et al [24], Dutta et al [25], Upinder [26] and Sharma et al [22] in their studies.…”

Effect of Bio sulphur granules (BSG) as fertilizer ingredient on different fractions of sulphur in calcareous soil cultivated with blackgram (Var.VBN-8)

“…The addition of S fertilization with oxidizing micro organism to calcareous soil favoured solubilization of the sulphate that was coprecipitated with CaCO 3 , and the solubilized sulphate was partly transformed into soluble inorganic form (Hu et al, 2005). The results conformed with the observations recorded by Sharma et al (2014); they showed that zero fertilization led to a decline in the levels of all S forms, while application of S-containing fertilizer and organics increased it over control. This might be due to the release of S from inorganic and organic S sources applied to different treatments, and the treatments which recorded lower inorganic S were due to continuous crop removal without the addition of any S source and conversion of the inorganic form of S to SO 4 2--S (Roshiniet al, 2021).…”
