What is one effect of immobilization on nitrogen availability in soil?

• A. Increases nitrogen availability
• B. Leads to nitrogen deficiency
• C. Enhances crop yield
• D. Promotes microbial growth

Answer: (B)

Immobilization refers to the process where inorganic forms of nitrogen, such as ammonium or nitrate, are converted into organic forms by soil microorganisms. During this process, the nitrogen becomes temporarily unavailable for plant uptake because it is being used by bacteria and fungi to synthesize their own proteins and nucleic acids. This can lead to lower levels of nitrogen in the soil that plants can access, potentially resulting in nitrogen deficiency, especially in the early stages of plant growth when nitrogen demand is high. While immobilization is crucial for nutrient cycling and maintaining soil fertility, its immediate effect can often reduce nitrogen availability, leading to symptoms of deficiency in crops. This situation highlights the importance of understanding microbial dynamics and nutrient management to ensure that plants receive adequate nitrogen throughout their growth cycle.
