← GeographyWhat effect results when high levels of aluminum inhibit pedogenesis?
A)Phosphorus availability severely declines✓
B)Soil experiences increased water retention
C)Nitrogen fixation rates drastically improve
D)Potassium compounds become more bioavailable
💡 Explanation
Aluminum blocks phosphorus uptake because adsorption reactions with aluminum oxides dominate mineral surfaces instead of organophosphates during pedogenesis; therefore, phosphorus becomes largely unavailable to plants, rather than being more accessible mineral forms.
