The soil type is an important factor influencing the occurrence
of trace element deficiencies in grazing animals in New Zealand. Cobalt
and selenium deficiencies occur mainly on soils from acidic rocks.
Cobalt deficiencies may also occur on soils from more basic parent
materials where the soils have been strongly leached. Selenium
deficiencies is less easily predicted on the basis of soil
characteristics. Copper deficiencies are more likely in stock grazing
on peat soils, gley soils, certain pumice soils, saline soils, recent
soils and some steepland soils. For all 3 elements, classification of
occurrences of deficiency by soil type has provided a basis for
delineating areas where deficiencies are likely, areas where they are
unlikely and areas of marginal status. This has enabled a rational
approach to investigations and the application of treatment and control
measures.
