“…Because of high pH of SBC (pH 8.5), it could extract a part of organically bound S, particularly from the ester sulphate (Kilmer & Nearpass, 1960) extractability of CC was attributed to its extraction of only soluble sulphate, not even the adsorbed part (Tabatabai, 1982). Similar extractability of the extractants for S in soils was reported from soils of Germany (Bloem et al, 2002), USA (Ketterings et al, 2011(Ketterings et al, , 2014 and in terai soils of India (Paul & Mukhopadhyay, 2014). The decrease in S content with an increase in depth (by CC, MR, HCl and SBC) was associated with a decrease in organic C content of the soils, as evidenced by the existence of significant positive correlations between the extractable S and the soil organic C (Table S1).…”

Sulphur (S) deficiency is widespread in agricultural fields across the globe. Its flow in the soil–plant system under different management practices is too poorly understood to strategize S fertilisation with increased efficiency. Accordingly, an attempt was made to elucidate the pathways of S flow in soils and to plants under organic, inorganic, and integrated nitrogen (N) management practices using a 30‐year‐old long‐term field experiment planted with sorghum in the semi‐arid tropics. Partitioning soil S into pools, we observed that exchangeable (4.2%) and adsorbed (4.6%) pools constituted a small part of total soil S but contributed mainly to S nutrition (46% and 33%) of sorghum; it also contributed to the variability of S extractable by six commonly used extractants. Using multiple criteria, the superiority of monocalcium phosphate as an extractant for assessment of S in Vertisols was established. Among the N management practices, integrated N management performed better in supplying S in soils and to sorghum, and excelled, both in retention (35.9% of applied) and utilisation (13%) of S, curbing its losses (51.1%) from the system, over the organics (26%, 8.4%, and 65.6%, respectively) and inorganic (11.6%, 7.1%, and 81.3%, respectively) management practices. The integrated management practices with farmyard manure (FYM) excelled in improving S in soils, including economics. Out of the organics, FYM was more effective in improving S availability in soils and its nutrition of the crop over the crop residue, and green manure. Changes in organic C, and oxides and hydroxides of Fe and Al in soils are the keys governing the flows of S in the soil–plant system. A detailed pathway of the increased efficacy of S fertilisation upon conjoint application of N sources over the others was highlighted for adoption in Vertisols of semi‐arid tropics. Highlights Inter‐relationship between pools and extractants of S were elucidated. Organic C and sesquioxides played a key role in S transformation in soils. Monocalcium phosphate was the most sensitive extractant for S in soils. Sixty two percent of the applied S was lost, 28% retained and 10% utilised.

“…The method of Blair et al (1991) modified by Bloem et al (2002) was used to determine S concentration of soil samples. According to the method modified by Bloem et al (2002) , 10 g of soil passed through a 2 mm sieve and 50 ml of 0.025 M KCl solution was added to it. Afterwards soil-KCl suspension was shaken at 100 rpm in a horizontal shaker for 3 h at room temperature.…”

Sulfur (S) deficiency in soils and plants has been increased in the recent decade which is reducing crop yield and quality. Unfortunately, no extensive study has been conducted on S nutritional status of plants in Turkey. In this study, soil and plant samples were collected from Çukurova, Central Anatolia and GAP regions where wheat is extensively cultivated. Plant samples either as flag leaf or the whole shoot were collected depending on growth stage of wheat crop at sample collection. Similarly, surface (0–20 cm) and sub-surface (20–40 cm) soil samples were collected from plant sampling sites and a total 963 plant and 1947 soil samples were collected during the study. The S concentration in flag leaf samples varied between 0.18 and 0.67%, 0.11–0.59% and 0.17–0.82% for central Anatolia, Çukurova and GAP regions, respectively. According to S concentration in flag leaf samples, 99% of the plants in Çukurova region were found sufficient in S nutrition. However, 49% of the samples collected from central Anatolia and GAP regions were deficient in S. Critical N:S ratio indicating S nutrition status of plants was lower than the widely accepted critical value of 17. This low N:S ratio was a consequence of deficient N nutrition rather than S nutrition. Moreover, it was observed that plant available SO 4 -S concentration of soils varied within and among sampled provinces with an average value of 20.6 and 31.6 mg kg −1 for surface and sub-surface samples, respectively. The SO 4 -S concentration increased with increasing soil depth. The results indicate a significantly positive correlation between S concentration in plant shoot and plant available SO 4 -S concentration in soils. In conclusion, S-containing fertilizer use in central Anatolia and GAP regions must be considered as an important approach for the prevention of yield and quality losses. Furthermore, rapid and sensitive plant and soil analysis methods are needed, which must also consider the local and site-specific conditions.

“…A greenhouse experiment was conducted with a bread wheat (Bezostaja), three different soils ((0.025 M KCl extractable S: Harran:14.7 mg SO 4 -S kg -1 , Eskişehir :12.2 mg SO 4 -S kg -1 and Konya: 18.3 mg SO 4 -S kg -1 ; (Bloem et al,2002)); three different sulphur sources (K 2 SO 4 , CaSO 4 .2H 2 O and Elemental-S) and four different sulphur doses (0, 25, 50 and 100 mg S kg -1 ). Some physical and chemical properties of the soils used in the experiment are given in table 1.…”

Deficiency of sulphur (S) is an important limiting factor of plant growth for sustainable agricultural production. The decline in sulphur dioxide emission, decrease in S-containing fertilizer consumption due to the high cost of S-fertilizers, breeding of new high yielding species are the well known causes of S-deficiency. A greenhouse experiment was conducted to investigate the effects of several doses of K2SO4-S, CaSO4-S and elemental-S applied on growth, shoot dry matter yield, S and N concentrations of wheat cultivar. The experiments were conducted in three soils differed from available S concentrations. Effects of different S-treatments (0, 25, 50 and 100 mg S kg-1) and S-forms had significant effects on shoot dry matter yields of plants. Sulphur from different S-sources did not increase shoot S-concentrations in Eskisehir and Konya soils, but increase was significant obtained in the Harran soil. Shoot S-concentration in Harran soil for zero K2SO4 treatment was 0.09%, the values were 0.22, 0.26 and 0.27% respectively for 25, 50 and 100 mg kg-1 treatments. The results indicated significant effects of S-treatments on plant growth and yield mostly based on soil properties, especially the available S-levels
