What Is The Role Of Nitrogen In Plants Growth?

Below are a few points that how nitrogen helps plants grow and function better.

  • Plants need numerous nutrients and vitamins to grow, and nitrogen is one of them. By using nitrogen, they grow themselves.
  • Plants cannot make amino acids, proteins, and DNA if they don’t have sufficient nitrogen.
  • If the plants are nitrogen deficient, they will stop growing or developing. 
  • Besides this, plants even can’t make their cells because of low nitrogen levels in the soil.  
  • Moreover, there is almost 78% nitrogen in the environment. 

It’s essential to convert nitrogen from the air in some other form, to transfer it from the soil to plants. This can be done by the nitrogen fixation method or by recycling nitrogen using manure and plants’ composition.

Which Plants Usually Live In Nitrogen Poor Soil?

Nitrogen fixation plants like beans, legumes, and peas can survive at a low nitrogen level as they add nitrogen to the soil while growing. 

These plants don’t absorb the soil’s nitrogen; they convert the atmospheric nitrogen to use as the nutrients in the ground. 

How Long Does It Take Nitrogen To Leave Soil?

When the nitrogen starts making compounds like Nitrites and Nitrates, the level of nitrogen starts decreasing. This process is known as nitrification. It almost takes 2 to 6 weeks for the procedure. 

Wild plants and animals can consume nitrates, and the bacteria convert nitrites into nitrates, so plants or animals can consume them. 

However, nitrification is an essential procedure for plant growth. Under the nitrification process, an extra stash is produced, and plants can take this extra stash of nitrogen from the roots.
