lime, sir-slacked lime, or ground lime
stone 10 still the subject of great des
Of csntroversy. The sAvocsass ol
greuad limestone claim thet the cousti,
properties Of quick or hydrstsA hms
will bSrn up end destroy the srgani,
matter in the soil, whereas limestone
can be applied in large quantities d
long intervals snd will therefore pro
dace . more or less permanent fertility
The advocates of lime claim that one Of
the main functions which lime has 3,
perform is the obstruction of the organic
matter and the liberation of the nitro
gen in such form that the plant car
use it; that the frequent and judiciou,
use of lime, together with some organic
fertilizer, will bring immediate results
OF course the local conditions of each
particular case must be considered be.
fore final conclusion can be reached
Thus. it is rational to use quicklime or
soils which are exceedingly rich in or
ganic matter, such rs pesty or swampy
soils. Limestone is safer than quick.
lime when applied just before planting
crop which is little helped by Inning,
or when applied to light sandy soil in
hot dry weather.
