Optimal is key to preventing soil acidification

The soil carbonic acid starts hydrolysing the limestone.The calcium carbonate or magnesium carbonates dissolve and are then hydrolysed to give calcium to the soil. Exchangeable hydrogen and aluminium are replaced by the calcium. Neutralisation of the hydrolysed limestone surface area increases in calcium concentration at this point.
