Once in the soil, the hydroxide soon undergoes this change and combines with carbon dioxide and other acid radicles like niti and becomes calcium carbonate again, or calcium nitrate as the case ma] be. Calcium carbonate, the principal calci im salt in the soil, is not readily removed, though since it serves as a weak base against acidity and is itself soluble in water contain- ing carbon dioxide, the store of calcium carbons slowly depleted: and where a soil is not naturally rich in this mineral, its artificial application is generally advisable particularly oi i rj ind pi it] soils. The importanci J calcium carbonate as evidenced by these considerations based on experiments conducted m temperate countries leads one to ask whether the mineral is adequately employed in the Tropics.
