Nutrient Function

Zinc Icon
Zinc helps facilitate enzyme function for protein synthesis and carbohydrate metabolism in the plant. It is essential for chloroplast formation and auxin metabolism. Auxins are plant hormones that help regulate growth and development, including cell division and flower initiation. Low zinc levels in the soil can increase vulnerability to root diseases such as phytophthora.
Copper Icon
Copper is essential for photosynthesis and facilitates enzyme production for carbohydrate and protein metabolism. The nutrient influences pollen formation, viability and fertilization, thus affecting fruit set. Low levels of copper in acidic soils can lead to an accelerated uptake of manganese that could be toxic to the plant. Copper sprays can be used to manage bacterial and fungal diseases in fruiting crops.
