Zinc is needed by plants in small amounts, but yet crucial to plant development.

Zinc is a key constituent of many enzymes and proteins. It plays an important role in a wide range of processes, such as growth hormone production and internode elongation.

Zinc activates enzymes that are responsible for the synthesis of certain proteins. It is used in the formation of chlorophyll and some carbohydrates, conversion of starches to sugars and its presence in plant tissue helps the plant to withstand cold temperatures.

Zinc is essential in the formation of auxins, which help with growth regulation and stem elongation.

Zinc deficiency causes a type of leaf discolouration called chlorosis, which causes the tissue between the veins to turn yellow while the veins remain green.

The mobility of Zinc in plants varies, depending on its availability in the soil or growing media. When Zinc availability is adequate, it is easily translocated from older to younger leaves, while Zinc is deficient, movement of Zinc from older leaves to younger ones is delayed.


It is hard to tell the difference between Zinc deficiency and other trace element or micro-nutrient deficiencies by just looking at the plant because they all have similar symptoms. The main difference is that chlorosis due to Zinc deficiency begins on the lower leaves, while chlorosis due to a shortage of Iron, Manganese or Molybdenum begins on the upper leaves. The only way to confirm your suspicion of Zinc deficiency is have your soil/plant tissues tested and analysed.
