Phosphorus, sulphur, and molybdenum deficiencies in soils from eastern Australia in relation to nutrient supply and some characteristics of soil and climate locations
Aims

To resport on the extent to which deficiencies in phosphorus, sulphur, and molybdenum likely to be associated with deficiencies in the others.

Key messages
  • A pot study using 32 virgin soils from south-eastern Australia (Vic - Qld).
  • Subclover grown in pots in the glasshouse and nutrient relations examined.
  • Sulphur deficiency occurred almost as frequently as phosphorus deficiency.
  • 75% of the soils were deficient in both phosphorus and sulphur, 31% were deficient in all three elements.
  • Molybdenum responses were obtained only after the other deficiencies had been corrected.
  • A deficiency in one of the elements is no indication of deficiency or sufficiency of either of the other two.
  • Responses to phosphorus were less on the black earths than on the red or yellow podzolic soils; those on the red earths were intermediate.
  • The intensity of sulphur deficiency increased, and the intensity of molybdenum deficiency decreased, with increasing soil pH.
