We’ve been learning that a plant needs water, air, and sunlight for its growth.
But how many of you know that Nitrogen too is an important element for a plant’s growth?
Nitrogen occupies about 78%(which is more than oxygen’s occupancy) of the atmosphere.
Yet, plants cannot acquire nitrogen directly from the air.
Plants acquire nitrone which is available in the soil in the form of nitrates, nitrites, etc.
Nitrogen helps in making proteins which is essential for plant growth.
