Absence or insufficiency of
sulphur needed for normal growth and development. |

| Sulphur deficiency is seldom a problem
in plant production. Whilst most soils contain sufficient sulphate,
"soilless" potting media usually have a fertiliser such as ammonium
sulphate or potassium sulphate added, in which case the sulphate is
a "carrier" for another element. Sulphur deficiency causes the
younger leaves of the plant to become pale green in colour,
particularly between the leaf veins |
