Which outcome results when excess sulfur inhibits soil bacteria?

A)Increased nitrogen fixation by mycorrhizae
B)Reduced phosphorus uptake by plants
C)Enhanced decomposition from fungal activity
D)Increased potassium availability in soil

💡 Explanation

Reduced phosphorus uptake occurs because high sulfur levels inhibit certain bacteria responsible for phosphorus solubilization, a crucial step for plant uptake, rather than increasing nitrogen fixation; therefore, phosphorus uptake decreases rather than other nutrients because phosphate solubilization is directly affected.
