Index >> Sulphur Phosphorus and Trace Element Nutrition >> Trace Elements

Trace elements deficiency of plants may be due to: (1) poor supply of one or more elements in a given soil, (2) inimical soil conditions which prevent the absorption and uptake of trace elements even when soils are not deficient with respect to some of the elements, (3) non-availability of trace elements in soil due to fixation in the presence of high "amounts of organic matter, (4) antagonism b,etween trace elements which may render them unavailable to plants and (5) under certain circumstances, microorganisms capable of converting the elements form a bound state to an easily assimilable form may be absent from soils. It is proposed here to briefly highlight some influences of microorganism  on the trace element nutrition of plants.
