Deficiency Symptoms of Essential Elements
The concentration of the essential element below which plant growth is retarded is termed as critical concentration.
The element is said to be deficient when present below the critical concentration.
The kind of deficiency symptoms shown in plants include chlorosis, necrosis, stunted plant growth, premature fall of leaves and buds, and inhibition of cell division
Chlorosis is the loss of chlorophyll leading to yellowing in leaves.
This symptom is caused by the deficiency of elements N, K, Mg, S, Fe, Mn, Zn and Mo.
Necrosis, or death of tissue, particularly leaf tissue, is due to the deficiency of Ca, Mg, Cu, K. Lack or low level of N, K, S, Mo causes inhibition of cell division.
Some elements like N, S, Mo delay flowering if their concentration in plants is low
