How does the soil's ability to hold onto anions change with soil pH?

Show Answers

Rises as soil pH becomes more alkalineIncreases when soil pH becomes more acidicStays constant regardless of pHNo effect on anion retentionVaries depending on soil type

Explanation

The soil's capacity to retain anions improves as the soil pH decreases, meaning more acidic conditions enhance anion retention. This is because lower pH increases positive charge sites on soil particles, which attract negatively charged anions.
