The basic necessity of all organisms is the same. For their growth and development, they all need mineral nutrition. This article will tell you about mineral nutrition in plants.
Process of making mineral nutrition solution
In 1860, Julius Sachs demonstrated that without soil, a plant had grown in the nutrient solution. Thus, he said that process of growing plants in mineral nutrition solution is hydroponics. After that many experiments would be performed for knowing the perfect amount of nutrition in the solution. All those experiments had performed with pure water and mineral nutrition. For knowing the proper amount of other minerals, dip and remove elements one by one in solution. After too many experiments, one solution was prepared which was perfect for the growth and development of the plant. Through this method, many other essential elements recognized and found the symptoms of their deficiency.
Most of the minerals present in soil are enter the plants through their root. Some species of plants accumulate selenium, some accumulate gold, etc. The 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 require in plants for their growth and development.
Symptoms of deficiency of mineral elements
The concentration which can stop the growth and development of plants during deficiency of mineral elements is called critical concentration. Every element has a special role in plant development. Consequently, deficiency of one element can affect plants in different ways. If this shortage persists then the plant can die. If the plant has some minerals deficiency then some symptoms appear 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 lead to form different types of minerals.
