“…MIN -mineral fertilizer; FYM1 -9 t/ha farmyard manure; FYM2 -18 t/ha farmyard manure; COM1 -14.5 t/ha compost; COM2 -58 t/ha compost; SS1 -3.7 t/ha sewage sludge; SS2 -14.8 t/ha sewage sludge ability among the organic residues. While sewage sludge, for example, has a large pool of potential mineralizable S, compost (with a higher C/S ratio) encourages microbiological immobilization of S. According to Wang et al (2006) total organic S in soil is highly significantly correlated with total soil organic carbon, indicating a close association between C and S. Confirming results of Eriksen and Mortensen (1999) we also found that build up of organic C (C org ) ( Table 1) was followed by a similar build-up of organic S. The correlation between both parameters is highly significant (R 2 = 0.80). Ester sulfate accounted for 36.3 to 51.6% of total organic S, which is in the same range as reported by .…”

“…Although in most soils organic S accounts for 90% of total S or more relatively little is known about the chemical characteristics of organic S compounds (Wang et al 2006). Traditionally two main groups can be distinguished, namely C-bonded S and HI-reducible S. A few other organic S formsthought to be sulfonates and heterocyclic sulphur -also exist, but they are of comparatively minor importance (Kertesz and Mirleau 2004).…”

A field experiment established in 1962 on a luvisol derived from loess was chosen to investigate the effect of longterm application of farmyard manure, compost and sewage sludge, respectively, in two increments on inorganic and organic S fractions in bulk soil. Compared with mineral fertilizer, the high application rates of the different organic fertilizers (10 t farmyard manure (FYM2), 29 t compost (COM2), 7.44 t sewage sludge (SS2)/ha/year, respectively), resulted in an increase of the total S content in the bulk soil: 220 mg/kg (FYM2), 298 mg/kg (COM2), 277 mg/kg soil (SS2) as compared to the control (MIN) with 158 mg/kg soil. The sum of water soluble plus adsorbed S was significantly higher in the treatments with the high amount of compost (17.9 mg/kg soil) and sewage sludge (16.4 mg/ kg) soil as compared to all the other treatments (10.0 to 13.1 mg/kg soil). The treatments with the high amounts of organic manures contained lower contents of ester sulfate and higher contents of C-bonded S as compared to the treatments with the low amounts, and vice versa.

“…Inorganic sulfur, on which is mainly focused this manuscript, represents usually less than 10% from total S (Tisdale et al 1993, Wang et al 2006) and appears in different forms. The most important form for S uptake by plants is bioavailable sulfate (SO 4 2-) in the soil solution.…”

The aim of this work was to evaluate the changes of different soil sulfur forms during long-term field experiments supplied with sewage sludge (SS), farmyard manure (FYM) or mineral fertilizers. The experiment was established at three different sites with the crop rotation of potatoes, wheat and barley. Fertilizing system was based on the same nitrogen dose per the whole crop rotation. Soil samples from the beginning of the experiment (1996) and at the end of each crop rotation were analysed after all three crops harvest. Similar tendencies of changes in water extractable (S w ), adsorbed (S ads ), 1 mol/L HCl estimated (S HCL ) sulfur and their sum of (∑S) related to the fertilizing systems were observed among all studied sites. A decreasing tendency of ∑S in soil was observed during the experiment (except for the year 2005). The biggest decrease was always visible compared to control treatment. Mineral fertilizers (S added with superphosphate) appeared to be the best source of S HCL . Application of SS increased the S w content in soil samples after potatoes harvest, whereas a decreasing tendency among the following crops was visible. Contents of other S forms (S w at control, FYM and mineral fertilizers included) were usually balanced during the crop rotation.

Dissolved organic sulfur (DOS) is an important fraction for sulfur mobilization in ecosystem. In this work stream waters were sampled in 25 forested sites in southern China to study the dissolved sulfur fractions. Dissolved sulfur was fractionated into dissolved organic sulfur (DOS) and inorganic sulfate (SO 2− 4 ) for 95 stream water samples. The results showed that the concentration of DOS ranged from 0 to 13.1 mg/L (average 1.3 mg/L) in all the streams. High concentrations of DOS in stream waters were found in the sites with high concentrations of sulfate. DOS constituted less than 60.1% of dissolved sulfur (average 17.9%). Statistical analysis showed that DOS concentration was correlated with SO 2− 4 in streams waters and total sulfur in surface layer soils. The results also showed that DOS concentration in stream waters had a seasonal variation, but no trends were found with it. The implication was that the long term sulfur deposition had led the increase of the concentration and fraction of DOS in stream waters in acid rain prevailing regions
