reserve acidity

The exchangeable H+ ions held on the soil colloids and hydrolysable AI3+ are referred to as reserve or potential acidity. Reserve acidity is in dynamic equilibrium with H+ ions in the soil solution (active acidity). Conservative calculations suggest that reserve acidity may be 1,000 to as much as 100,000 time greater for a clay soil than active acidity.
