“…These trends were similar to those already described for soil S ( Table 1), suggesting that sulphate in superphosphate might have been lost by leaching (Toxopeus 1970) or incorporated into the soil organic pool (Goh & Gregg 1982;Freney 1986). …”

“…The absence of any evidence of accumulation of sulphate at depth, however, means that organic immobilisation of S in the topsoil (Goh & Gregg 1982) cannot be excluded as a reason for the decrease in phosphate-extractable S.…”

“…This may be a result of sulphate immobilisation into soil organic matter (Freneyetal.1975;Goh & Gregg 1982) and leaching losses beyond the soil sampling depth of 7.5 cm (Gregg & Goh 1979), caused by irrigation water and rainfall. Using a pasture development index, which takesintoaccountthenumberofyearsunderryegrassclover pastures and the average stocking rate over this period (Sinclair & Saunders 1984), the low soil sulphate in late winter suggests that sulphatecontaining fertilisers would be required in the following spring for all treatments.…”

“…The accumulation of soil P and S reserves in grazed pastures has also been reported in other studies in New Zealand (Walker et al 1959;Jackman 1964) and Australia (Barrow 1969;Simpson et al 1974;McLachlan & De Marco 1975;Lewis et al 1987a,b). This accumulation may occur through the immobilisation of applied P and S in soil (Cosgrove 1977;Goh & Gregg 1982), adsorption-precipitation of phosphate on soil colloids (Barrow 1980), and the returns of these elements through plant litter or animal excreta (Ti1l1975; Gillingham et al 1980).…”

“…Blair et al (1994) found a mean recovery of 28.1% of the applied 35 S into the soil organic S-pools in their pot experiment. Goh and Gregg (1982) also showed that the fertilizer S could be rapidly converted into organic forms and found that 17-40% of the applied 35 S to be in the organic form within 34 to 75 d of fertilizer application. A small amount of applied 35 S might also be adsorbed by the clay and organic matter colloids, but this adsorption should be very low in the present study, as indicated by the soil characteristics data.…”
