Which outcome is caused by limited soil aeration?

A)Inhibited nitrogen fixation efficiency
B)Increased root uptake of phosphorus
C)Enhanced mycorrhizal network spread
D)Accelerated decomposition of cellulose

💡 Explanation

Inefficient soil aeration limits oxygen; therefore anaerobic conditions arise, inhibiting nitrogen fixation because the nitrogenase complexes, crucial for the process, are highly sensitive to oxygen toxicity, rather than promoting phosphorus uptake.
