Plants need minerals for healthy growth

 

There are 7 types minerals that a plant requires for healthy growth, three of them are essential.  These enter the plant through the root hair cells by active uptake in the form of ions in solution (in water).  They pass into the root and travel through the xylem to the rest of the plant.  The 3 essential minerals are required in fairly large quantities and they are:

Nitrates - essential for the production of AMINO ACIDS, DNA and Proteins.

Phosphates - have crucial role in carrying out photosynthesis and respiration.  They are also important components of DNA and cell membranes

Potassium - it activates the enzymes that carry out respiration, photosynthesis and makes ATP (energy molecule).

The other 4 minerals are only used in very small amounts and they are:

Magnesium and Iron - both are required for making chlorophyll.

Sulphur - required for healthy root growth.

Calcium - helps in the cell wall formation.

 

Lack of these minerals lead to deformed growth in a plant.

Lack of Nitrates -  results in reduced plant growth and leads to  yellow spotting of leaves, known as chlorosis.

Lack of Phosphates - results in poor root growth and chlorosis.

Lack of Potassium - results in yellow spotting of leaves - chlorosis.

Lack of Magnesium - results in yellow spotting of leaves - chlorosis.

Lack of Iron - results in yellow spotting of leaves - chlorosis.

Lack of Iron - results in yellow spotting of leaves - chlorosis.

When farmers use only one type of crop in the same field year after year (Monoculture), the soil becomes deficient in the minerals which that particular plant uses lots of.  If plants do not have all these essential minerals, they will suffer from deficiency disease.  Hence, farmers use fertilisers  to protect their crops from disease and ensure good quality fruit, yield or plants.  Fertilisers replenish lost minerals.
