Copper Deficiency
Copper is needed for protein synthesis, and in deficiency, there is a
build-up of non-protein nitrogen compounds in leaves. Copper activates
several enzymes, and in a severe deficiency, plants are stunted, exhibit
delayed maturity, or may fail to grow altogether.
Copper deficiency is often seen on acid soils, or soils with low levels
of organic matter. Usually, when visual deficiency symptoms (wilting of
young leaves and chlorosis) become apparent, the damage to productivity
is already done. Deep- rooted crops such as canola and lupin respond
well to applications of copper, when levels of organic matter at depth
are low. Grain analysis, and treatment of soil, or foliar applications
can ensure productivity is not lost.
Application Rates: Apply Soil and Foliar Copper early to soil, at
a rate of 2 litres per hectare for mild deficiency, or for severe
deficiency, at a rate of 3 litres per hectare.
Water (minimum): Broad-acre crops at 50 litres per hectare and
horticultural crops at 400 litres per hectare.
