intensive fertilizer use on vegetables), and in
arid areas. In hot, dry areas a high rate of
evaporation from the surface causes soil water to
move upwards and with it the salts it contains
which may reach toxic levels to plants when
accumulated in the surface layers of the soil. On
average, concentrations of chloride in the
external solution of more than 20 mM can lead to
toxicity in sensitive plant species, whereas in
tolerant species (e.g. barley, spinach, lettuce
and sugar beet), the external concentration can
be four to five times higher without reducing
growth.
The principal effect of Cl deficiency in plants
is a reduction in leaf surface area and thereby
plants dry weight. With severe deficiency,
necrosis might occur. In leaves and roots,
besides cell division, cell extension is
particularly impaired. Cl deficiency may occur in
highly leached soils with a low Cl input from
rain in areas far distant from oceans.
