Explain the advantages of using slaked lime instead of powdered limestone for neutralising acidic soil?

Slaked lime is much more alkaline and effective at reducing acidity quickly - it is Ca(OH)2
whereas powdered limestone is CaCO3 and not as alkaline/basic. CO2 is also given off when the limestone reacts with the acid. Water is given of when slaked lime reacts.
Mathematically it takes 100 g of limestone to 73g of HCl (as an example) where it would take only 74g of slaked lime per 73g HCl.
