Necessity of mineral nutrition in plant

The basic necessity of all organisms are the same. For their growth and development, they all need mineral nutrition. This article will tell you about mineral nutrition in plant.

Mineral nutrition in plant

Process of making nutrient solution

In 1860, Julius Sachs demonstrated that without soil, a plant had grown in the nutrient solution. Thus, he said that process of growing of plants in mineral nutrition solution is hydroponics. After that many experiments would performed for knowing the perfect amount of nutrition in solution. All that experiment had performed with pure water and mineral nutrition. For knowing the proper amount of other mineral, dip and remove elements  one by one in solution. After too many experiments, one solution prepared which was perfect for growth and development of plant. Through this method many other essential elements recognized and found the symptoms of their deficiency.

Essential minerals

Most of the minerals present in soil  are enter the plants through their root. Some species of plants accumulate selenium, some accumulate gold, etc. Minimum concentration of elements in plants is 10-⁸g/ml.

On the basis of their required quantity minerals are divided into two types.

  • Macro elements- Calcium, phosphorus, nitrogen, potassium, magnesium, sulphur, oxygen, carbon and hydrogen.
  • Micro elements- Boron, copper, Iron, Manganese, Molybdenum and Zinc.

These all elements requires in plants for their growth and development.

Symptoms of deficiency of mineral elements

The concentration which can stop the growth and development of plant during deficiency of mineral elements is called critical concentration. Every element has special role in plant development. Consequently, deficiency of one element can affect plant in different ways. If this shortage persists then plant can dies. If plant has some minerals deficiency then some symptoms appears like immature leaves, falling down the buds, yellowish leaves, etc.

Rocks form these types of minerals. Rock collision occurs to form minerals. The pressure and temperature of the environment leads to form different types of minerals.
