Nitrogen fixation is the part of the nitrogen cycle where the nitrogen is fixed as nitric oxide. Urea {CONâ‚‚Hâ‚„} should be added to fertilizer to get the best results. Thus, option B is correct.
Fertilizers are substances that are composed of organic and inorganic compounds that are used to provide nutrients to the plants and crops for growth, development, pest, and insect resistance.
The fertilizers mainly comprise nitrogen, potassium, and phosphorus. Urea {CONâ‚‚Hâ‚„} has the maximum concentration of nitrogen (46%) and will be the most effective.
The other compound ammonium nitrate {NH₄NO₃} contains 34%, ammonium sulfate { (NH₄)₂SO₄} which comprises 21% of nitrogen by mass, whereas N₂F₂ is not used as a fertilizer.
