The Kind To Apply
If a soil contains free acid, the amount of calcium
needed is definite. The form of lime that can supply the need in that
particular field at least expenditure of money and trouble is the one
to be selected. A ton of stone-lime, or pulverized lime, can correct as
much acid as 2640 pounds of hydrated lime or 3570 pounds of pulverized
limestone, if all the original material was pure.
In other words, if the value of a given weight of pulverized limestone
is placed at 100, the value of the same weight of hydrated lime would
be 132 and the value of stone-lime would be 180, when each was finely
divided and distributed throughout the surface soil.
