Trasco Manganese as a trace
element for crop plants
Manganese is necessary in photosynthesis,
nitrogen metabolism and to form other
compounds required for plant metabolism.
Interveinal chlorosis is a characteristic
manganese-deficiency symptom. In very
severe manganese deficiencies, brown necrotic
spots appear on leaves, resulting in premature
leaf drop. Delayed maturity is another
deficiency symptom in some species. Whitish-gray
spots on leaves of some cereal crops and
shortened internodes in cotton are other
manganese-deficiency symptoms.
Manganese (Mn) is mainly
absorbed by plants in the ionic form Mn
++ . Manganese may substitute for Mg by
activating certain phosphate-transferring
enzymes, which in turn affect many metabolic
processes. High Mn concentration may induce
Fe deficiency in plants.
Manganese availability is closely related
to the degree of soil acidity. Deficient
plants are usually found on slightly acid
or alkaline soils. Liming Florida soils
to pH above 6.5 frequently causes Mn deficiency.
Manganese deficiencies mainly occur
on organic soils, high-pH soils, sandy
soils low in organic matter, and on over-limed
soils. Soil manganese may be less available
in dry, well-aerated soils, but can become
more available under wet soil conditions
when manganese is reduced to the plant-available
form. Conversely, manganese toxicity can
result in some acidic, high-manganese
soils. Uptake of manganese decreases with
increased soil pH and is adversely affected
by high levels of available iron in soils.
In legumes, deficiency symptoms include
pale green young leaves and a pale yellow
mottling develops in interveinal areas,
while the veins remain green. Oats are
an excellent indicator crop. Manganese
is partly mobile in oats. White to grey
flecks or specks first appear and become
more severe on mature leaves about halfway
up the shoot. If a deficiency persists,
symptoms spread to old leaves then to
the youngest leaves. The specked condition
is referred to as "grey speck"
and will appear in the interveinal area
of the lower half of older leaves and
extend toward the tip as symptoms develop.
Manganese is not readily transferred
from old to young leaves in wheat and
barely. In wheat and barley, affected
young leaves frequently turn pale green
and have a limp or wilted appearance.
A mild interveinal chlorosis develops
in the mid-section of the leaf and spreads
rapidly becoming pale yellow-green. Small
white to grey spots, specks or strips
appear a short distance from the end of
the leaf tip on young leaves.
