Meaning
Plant deficiency diseases are diseases in plants caused by a lack of certain minerals.
About Plant Deficiency Diseases
- Plants gain minerals from the soil, so when the soil lacks certain minerals the plant can become ill.
- The three minerals most essential to a plants growth are Nitrates, Phosphates, Potassium, Manganese and Magnesium
Nitrate Deficiency
With a Nitrate deficiency the upper leaves grow light green and lower leaves are yellow and begin to shrivel.
Phosphate Deficiency
With a Phosphate deficiency the leaves grow dark and are regularly lost. Often the younger leaves are purple.
Potassium Deficiency
With a Potassium deficiency the tips and edges of young leaves are yellow. Over time more yellow patches or dead areas appear on the leaves.
Manganese Deficiency
With a Manganese deficiency yellow spots and holes appear between the plant veins.
Magnesium Deficiency
With a Magnesium deficiency the lower leaves a yellow area grows from the tips of the leaves spreading over the whole leaf while the veins remain green.
