“…Moreover, S 0 ensures enough availability of SO 4 2− by microbial action to be used by plants for longer times. On the contrary, Zhang et al [19] found that gypsum was more effective in reducing Cd accumulation than S 0 in rice plants. However, there are many mechanisms by which a plant minimizes Cd toxicity, including immobilization (binding of Cd to cell wall), compartmentalization (vacuolar sequestration), prevention (decreasing Cd entry into roots), and chelation (Cd-PCs mediated) [12].…”

“…Even in this case, S 0 showed the highest beneficial effects. Elemental S has been used in many studies in improving photosynthesis under various types of abiotic stresses [19,45]. The reason for increased photosynthesis under Cd stress with elemental S involves S-mediated allocation of N to Rubisco protein and through increase in stomatal conductance [41].…”

“…Moreover, the activity of enzymatic antioxidants increases in Cd-exposed plants after S supplementation, which lowers H 2 O 2 content, membrane peroxidation, and electrolyte leakage [12,18]. Sulfur is also known to restrain Cd transport to shoot and reduce Cd accumulation by promoting the synthesis of non-protein thiols (NPTs) pool (including PCs and GSH) [19]. Furthermore, reduced glutathione (GSH) was reported to scavenge excess ROS via AsA-GSH cycle and reduce Cd-induced phytotoxicity [17].…”

The effect of four soil-applied sulfur (100 mg S kg−1 soil (100S) and 200 mg S kg−1 soil (200S)) in different sources (elemental S, ammonium sulfate, gypsum or magnesium sulfate) in protecting mustard (Brassica juncea L. (Czern & Coss.)) from cadmium effects was studied. Based on the observed reduction in growth and photosynthesis in plants subjected to 100 and 200 mg Cd kg−1 soil, B. juncea cv. Giriraj was selected as the most Cd-tolerant among five cultivars (namely, Giriraj, RH-0749, Pusa Agrani, RH-406, and Pusa Tarak). Sulfur applied to soil mitigated the negative impact of Cd on sulfur assimilation, cell viability, and photosynthetic functions, with a lower lipid peroxidation, electrolyte leakage, and contents of reactive oxygen species (ROS: hydrogen peroxide, H2O2, and superoxide anion, O2•−). Generally, added S caused higher activity of antioxidant enzymes (ascorbate peroxidase, catalase and superoxide dismutase), contents of ascorbate (AsA) and reduced glutathione (GSH); increases in the activities of their regenerating enzymes (dehydroascorbate reductase and glutathione reductase); as well as rises in S assimilation, biosynthesis of non-protein thiols (NPTs), and phytochelatins (PCs). Compared to the other S-sources tested, elemental S more prominently protected B. juncea cv. Giriraj against Cd-impacts by minimizing Cd-accumulation and its root-to-shoot translocation; decreasing cellular ROS and membrane damage, and improving Cd-chelation (NPTs and PCs), so strengthening the defense machinery against Cd. The results suggest the use of elemental S for favoring the growth and development of cultivated plants also in Cd-contaminated agricultural soils.

“…e processes of dissolution and recrystallization make heavy metals coprecipitation with Fe [48]. e formation of insoluble sulfide with heavy metals may be another cause of the reduction of F1 fraction under lower Eh [49]. Moreover, high water content during the aging experiment can increase soil pH [20].…”

Aging process of exogenous heavy metals in soil is significant for reducing their environmental risk due to the redistribution of species of soil heavy metals. A red soil (ultisol) and a brown soil (alfisol) were selected to investigate the aging process of cadmium (Cd), copper (Cu), and lead (Pb) under different regimes of temperature and water content. Most introduced heavy metals were all transformed from dissolved fraction to more stable fractions within 5 days of incubation. During incubation, most Pb existed in the fraction bound to Fe/Mn oxides, while exchangeable and carbonate-associated fraction was the dominant portion for Cd and Cu, suggesting that the transformation rate followed the order: Pb > Cu > Cd. The exchangeable and carbonate-associated fraction in red soil, which was characterized with higher pH and Fe/Al/Mn oxides and lower organic matter (OM), was significantly higher than that in brown soil, implying that soil OM was the important factor affecting the aging process of soil heavy metals in the present study. In addition, increases of temperature and soil water content can accelerate the transformation of most introduced Cd, Cu, and Pb to more stable forms in the soils. The results indicated that soil properties, environmental factors (i.e., temperature and water content), types of heavy metals, and pollution time can significantly affect the aging process of exogenous heavy metals.

“…Researchers have examined a lot of work on the key processes of sulphur cycling, which mainly focus on the releasing pattern of sulphur. Some of the researchers includes [8,9] studied the distribution and accumulation of sulphur in soil system [10,11], the mineralization and immobilization of organic sulphur by [12], the dissimilatory reduction process of sulphate and its coupling mechanism with carbon, nitrogen and iron studied by [13,14]. Understanding of various types of sulphur is essential for determining the long-term availability of sulphur and to formulate effective sulphur fertiliser recommendations.…”

Aim: The aim of the present study was to examine the different forms of sulphur fractions in post- harvest soil of cabbage crop to determine the S status of red sandy loam soil, Thondamuthur block, Coimbatore district. Study Design: The design used in the present study was Factorial randomized block design with 20 treatments replicated thrice. Place and Duration of Study: A field experiment was carried out in a farmer’s field of red sandy loam non-calcareous soil, deficient in sulphur which was located at Viraliyur village of Thondamuthur block, Coimbatore district during February to May 2021 of rabi season. Methodology: A field experiment was carried out in sandy loam sulphur deficient soil with cabbage as test crop fertilized with NPK along with different sulphur sources viz., elemental sulphur, potassium sulphate, gypsum and single super phosphate @ levels of 0, 20, 40, 60 and 80 kg ha-1 replicated thrice in a Factorial Randomized Block Design. S fractions of water-soluble S, inorganic S, organic S, available S and residual S were estimated in post-harvest soil. Results: The results revealed that the total sulphur differed from 278.1 to 339.4 mg kg-1. Among the sulphur fractions, inorganic S (39%) accounts highest proportion of total S followed by organic S (38.3%), water-soluble S (9.19%) and available S (4.12%). The order was, Inorganic S > organic S > sulphate S > water soluble S. Conclusion: This study indicated that all the sulphur fractions are strongly associated with S sources, levels and properties of red sandy loam soil of Coimbatore district under cabbage cultivation.
