“…A range of techniques including the use of radioisotopes (Till & May 1971;Goh 1978, 1979) and S balance calculations (Gillman 1973;During & Cooper 1974) have been used. A more direct technique is to measure the S content of drainage waters.…”

Losses of sulphur (S) in surface runoff and subsurface drainage waters were measured during a 2-year study on a grazed yellow-grey earth soil (Tokomaru silt loam). Dissolved sulphur (S) losses in subsurface drainage from pastures fertilised the preceding spring averaged 11.0 ± 3.5 kg S/ha per year. Application of 43 kg S/ha in late autumn-early winter increased dissolved S losses by 4.5 ± 1.5 kg S/ha. Dissolved S concentrations in the drainage were significantly correlated with water-soluble soil S, but total dissolved S losses were not. Losses of dissolved S in surface runoff were markedly affected by fertiliser addition and subsurface drainage. Losses from gently sloping (6°) plots were minimal except when fertiliser S was applied in late autumn to undrained pastures. Under these conditions, 8070 (4.5 kg S/ha) of the applied superphosphate was lost in surface runoff during a 6-week period. In another study, where dissolved superphosphate was applied in autumn, 13% (7.2 kg S/ha) of the applied S was lost in surface runoff from an undrained pasture.

“…The yellow-brown pumice soils, however, generally respond to S (During 1956;Hogg 1965;Hogg & Toxopeus 1966;Cooper & Hogg 1966;Toxopeus 1970) and responses have also been reported on northern podzols (Hogg & Cooper 1964;During 1967). The lower incidence of S deficiencies in the North Island compared with the South Island may be attributed partly to more widespread and generally heavier applications of superphosphate, and partly to the prevalence of soils with well developed anionretention properties, as exemplified by their capacity to retain phosphate (Saunders 1965).…”

“…However, it was not until the 1950s and 1960s that extensive field trials by Lobb, Walker, Ludecke, and others established the widespread extent of S deficiencies in the mainly hilly inland regions of Marlborough, Canterbury, and Otago, on soils derived from greywacke and schist, or from loess, alluvium, and colluvium of similar origins (Lobb 1954(Lobb , 1959Lobb & Reynolds 1956;Lobb & Bennetts 1958;Walker 1955Walker , 1957. Walker et al , 1956Walker & Adams 1958a;During 1956;Ludecke 1960Ludecke , 1962Ludecke , 1965Ludecke , 1966O'Connor 1962;Vartha 1963). The soils concerned were mainly zonal soils (Taylor & Pohlen 1968) at the weakly to moderately weathered end of the sequence (brown-grey earths, southern yellow-grey earths, high country yellow-brown earths).…”
