Some Chemical Methods of Determining the Lime Requirement of -soils

A research worker in soil chemistry accustomed to cbfidk$ions in England is soon conscious in New Zealand of many anomalies in the position that liming occupies in local farming practice. In the major%y of districts in Great Britain the periodical application of lime is an establish& practice, and when this practice is neglected the failure of crops or of pasture is quickly notciceable. Moreover, it is a simple matter in these districts to detect by laboratory methods the symptoms indicating a need for lime. New Zealand soils, however, frequently give reactions which, in England, would be considered as indicating high requirements for lime and yet when lime is applied, no marked increase in crop yield is exhibited.
