If the nitrogen cycle is hampered, the following environmental problems may arise:
- Loss of soil fertility – Proper conversion among nitrogenous compounds (NH₄⁺, NO₂⁻, NO₃⁻) is disturbed, so plants cannot absorb enough usable nitrogen, leading to poor plant growth and reduced crop yield.
- Water pollution and eutrophication – Excess nitrogen compounds may accumulate in water bodies, cause algal bloom and depletion of dissolved oxygen, leading to death of aquatic organisms.
