The five main deficiency symptoms arising in plants are:
Chlorosis
Necrosis
Inhibition of cell division
Delayed flowering
Stunted plant growth
Chlorosis or loss of chlorophyll leads to the yellowing of leaves. It is caused by the deficiencies of nitrogen, potassium, magnesium, sulphur, iron, manganese, zinc, and molybdenum.
Necrosis is the death of plant tissues as a result of the deficiencies of calcium, magnesium, copper, and potassium.
Inhibition of cell division is caused by the deficiencies of nitrogen, potassium, sulphur, and molybdenum. Delayed flowering is caused by the deficiencies of nitrogen, sulphur, and molybdenum.
Stunted plant growth is a result of the deficiencies of copper and sulphur.
