Question

Nitrogen is an essential nutrient for plant growth. But farmers who cultivate pulse crops like green gram, Bengal gram, black gram, etc. do not apply nitrogenous fertilizers during cultivation. Why?

Answer 1

Nitrogen fertilizers:

1. Pulse crops like green gram, Bengal gram, black gram, etc. include "rhizobium bacteria," farmers do not require nitrogenous fertilizers when growing them.
2. Chemicals called fertilizers are applied to crops to boost productivity.
3. Fertilizers containing nitrogen increase the quantity and caliber of agricultural output.
4. These bacteria are constantly present inside the root cells of leguminous plants.
5. They also fix atmospheric nitrogen gas and provide it to the plant as ammonia.
6. Rhizobium, industrial processes, and lightning are all capable of nitrogen fixation.
7. A commercial procedure called the Haber process is used to fix nitrogen.
8. Ammonia is created during this process by converting nitrogen.
9. Water, natural gas, which provides hydrogen, and iron, which serves as the catalyst are the basic ingredients needed for catalysis. Air provides nitrogen.
10. Rhizobium can also fix nitrogen. They transform it into inorganic nitrogen. After that, it is converted into amino acids, which plants use.
11. Lightning can fixate nitrogen as well. In this process, the atmosphere's nitrogen and oxygen combine to generate oxides of nitrogen.
12. These gases create weak nitric acid when they interact with rainwater. The soil mineral reacts with these traces of nitric acid to create nitrates.
