Which condition is likely to increase soil corrosiveness?

• A. Lower moisture levels
• B. Increased oxygen content
• C. Reduced acidity
• D. Decreased electrical conductivity

Answer: (B)

Increased oxygen content in the soil is likely to enhance the corrosiveness of the soil primarily due to its role in facilitating electrochemical reactions. When oxygen levels are higher, it contributes to the oxidation-reduction reactions that can accelerate the corrosion process of metals, particularly in moist environments. This is because oxygen acts as an electron acceptor, promoting reactions that can lead to the degradation of metal surfaces. Additionally, higher oxygen levels can support microbial activity, which can further influence the corrosion process by producing corrosive byproducts. The interaction of these factors makes increased oxygen content a key condition for enhancing soil corrosiveness. In environments where metal structures are buried, this increased corrosiveness can lead to more rapid deterioration, highlighting the importance of monitoring oxygen levels in relation to soil health and infrastructure integrity.
