Iron Deficiency
Although present in large amounts in most soils, only a small amount of
this important element is available to plants; hence its inclusion as a
trace element. Often accompanied by sulphur, iron activates chlorophyll
and is intimately involved in respiration and photosynthesis. In
combination with molybdenum, it is an essential ingredient of the enzyme
nitrogenase required for nitrogen fixation in legumes. Legumes need
sufficient levels of iron, cobalt and molybdenum for the maintenance of
legume bacteria in nodules.
Iron is not very mobile within the plant, and as a result, deficiency is
first seen on younger leaves at the top of the plant. In severely
deficient plants, leaves turn yellow and some to white. In cereal crops
growing in high pH soils, leaves develop yellow stripes with green veins
(interveinal chlorosis). The upper younger leaves can become completely
yellow and withered. Ideal levels of iron in leaves are hard to predict,
but in cereal grains range between 20 to 40 ppm.
Application Rates: Apply Soil and Foliar Iron whenever deficiency
is present, at the rate of 2 litres per hectare for mild deficiency, or
for severe deficiency, at the rate of 3 litres per hectare.
Water (minimum): Broad-acre crops at 50 litres per
hectare, and horticultural crops at 400 litres per hectare.
