“…Correlation between soil organic carbon and particle distribution -between 115-275 mg S/kg. This is in accordance with results of Solomon et al (2001), who reported that total S increased with decreasing size of the particles. As compared to mineral fertilizer application the influence of farmyard manure on total S in the different particle fractions was negligible, while the impact of compost and sewage sludge was more pronounced, but as compared to the control, only the high application rate of compost and sewage sludge, respectively, resulted in a significant increase of total S. However, it is difficult to explain, why we could not find an impact of farmyard manure.…”

A field experiment established in 1962 was chosen to investigate the effect of long-term application of farmyard manure (FYM), compost (COM) and sewage sludge (SS), respectively, in two increments as compared to mineral fertilizer on inorganic and organic S fractions in particle-size separates (< 0.002 mm, 0.002-0.02 mm, 0.02-2 mm). Independent of the particle-size the application of the high amounts of COM and SS resulted in the highest total S contents. It is evident that the particle-size fractions < 0.002 mm contained the majority of total soil sulfur (S). The content of plant available S (water-soluble and adsorbed SO 4 2-) decreased with increasing particle-size, while the influence of the kind and amount of organic fertilizers was negligible. As compared to C-bonded S sulfate esters were the dominant organic S fraction in size separates. The content of both organic S fractions was highest in the particle-size fraction < 0.002 mm and lowest in the particle-size fraction 0.02-2 mm. The influence of the application of organic fertilizers was less pronounced. Only high application rates of COM and SS, respectively, resulted in the highest contents of both organic S fractions in the particle-size fractions 0.002-0.02 mm and 0.02-2 mm.

“…While C-bonded S is directly derived from plant residues and root inputs as well as from microbial protein synthesis, sulfate ester is mainly generated through biochemical processes by the soil microorganisms, metabolizing organic residues (Solomon et al 2001).…”

“…In other words, in countries like Ethiopia where subsistence farming is practiced, the turnover of S through SOM is usually insufficient even to meet the small requirement associated with the small yields. Organic S pool which is the large proportion of soil S highly affected by long term cultivation in the tropics (Solomon et al, 2001) and further aggravated through removing plant residue. In intensive crop rotation S uptake can be very high, especially when the crop residue is removed from field along with the product (Fismes et al, 2002).…”

“…The content of organic sulfur ranges usually about 90% of total S in soil (Eriksen et al 1998, Solomon et al 2001 and includes (i) sulfur directly bound with carbon; (ii) sulfur indirectly bound with carbon, for example C-O-S and C-N-S bounds (Morche 2008) which can be approximately estimated using the extraction method according to Shan et al (1992). This method can be also used for estimating some part of inorganic sulfur (Havlin et al 2005).…”

Precise field experiments were established at 3 sites with oilseed rape under different soil-climatic conditions in the Czech Republic (Humpolec, Hněvčeves and Uhříněves) in the years [2008][2009][2010]. In this experiment, four fertilizing treatments with increasing S rate were evaluated. The contents of bioavailable (S W ), adsorbed (S ads ), occluded (S ocl ), and hydroiodic acid (HI) reducible (S HI ) sulfur were measured. The contents of the fractions within the studied sites in the samples collected before fertilizers application were comparable. The S W , S ads a S ocl contents did not exceed 10 mg S/kg. The S HI contents differed depending on site and year. Fertilizing using S as CaSO 4 positively influenced the contents of S W , S ads , and S HI in soil. Sulfur fertilizing had also the positive tendencies to increase the winter rape yields but the differences between studied treatments were not statistically significant.
