Answer 2

Available form of nitrogen for plants is either ammonium (NH4) or nitrate (NO3).

• The most common inorganic forms of nitrogen in plants soils are ammonium and nitrate.
• There are two types of ammonium: exchangeable and non-exchangeable.
• Nitrate and nitrous oxide are found in smaller amounts in soil.
• Plants generally use only ammonium and nitrate types of nitrogen.
• Plants are poisoned by nitrite.
• The nitrogen cycle commonly starts with nitrogen in its most stable form, dinitrogen (N2), and proceeds through the process of fixation, mineralization, nitrification, leaching, plant assimilation, ammonia volatilization, denitrification and immobilization to end with nitrogen in its most stable form, dinitrogen (N2).

Thus,answer to the above question is option (d) none of the above.
