what is nitrogen............?

Answer 1

heya friend!!☺☺
your question is really very interesting..
here's your answer!!☺☺

Nitrogen is a chemical element with the chemical symbol N, and atomic number 7, and is the most abundant element in the Earth’s atmosphere. Nitrogen is essential to life on earth because it is a key building block for nucleic and amino acids. Nitrogen is vital to plants because it is a major component in chlorophyll. Plants are able to absorb nitrogen in the form of nitrates that are found in the soil.

Nitrogen in the soil originates from two different sources, which are minerals containing nitrogen, and nitrogen in the atmosphere.

Nitrogen can go through many changes in the soil. These transformations are known as the nitrogen cycle, and are important for understanding nutrient and fertilizer management. Factors determining the quantity of nitrogen in the soil include previous fertilizer applications and nitrogen released by decomposition.

Although nitrogen is an essential nutrient for plants, too much nitrogen can be harmful. One side effect from excess nitrogen is that it can cause water to leach from plants, leaving them dehydrated. Excess nitrogen can also cause stunted root growth and excess foliage growth.
