Nutriment COPPER [Copper Sulphate (CuSO4.5H2O)] contains Copper 24% and Sulphur 12%.
COPPER is essential to the growth of plants. It plays a part in several enzyme processes and is key to the formation of chlorophyll. Copper activates some enzymes in plants which are involved in lignin synthesis and it is essential in several enzyme systems. It is also required in the process of photosynthesis, is essential in plant respiration and assists in plant metabolism of carbohydrates and proteins. Copper also serves to intensify flavor and color in vegetables and color in flowers.
Copper is immobile and its deficiency symptoms occur in the newer leaves. Symptoms vary depending on the crop. Typically, the symptoms start as cupping and a slight chlorosis of either the whole leaf or between the veins of the new leaves. Within the chlorotic areas of the leaf, small necrotic spots may form, especially on the leaf margins. As the symptoms progress, the newest leaves are smaller in size, lose their sheen and in some cases the leaves may wilt. The apical meristem may become necrotic and die, inhibiting the growth of lateral branches. Plants typically have a compact appearance as the stem length between the leaves shortens. Flower color is often lighter than normal.
Excess copper in the growing medium can restrict root growth by burning the root tips and thereby causing excess lateral root growth. High levels of copper can compete with plant uptake of iron and sometimes molybdenum or zinc. The new growth can become initially greener than normal, then exhibit symptoms of iron deficiency or possibly other micronutrient deficiencies. If not corrected, copper toxicity can reduce branching and eventually plant decline follows.
Copper is more available when the growing medium pH is low, so if copper toxicity is occurring, test the pH of the growing medium. Also certain fungicides have copper as their active ingredient, so it is essential to rinse the foliage off before testing the tissue. Legumes tend to be the most sensitive plants to copper toxicity.
For soil application: Dissolve 50g of Nutriment COPPER in 200 liters of water and spray on both the surface of leaves for one acre.
