The mineral constituents of some nyasaland tea leaves and tea soils

Analyses of the mineral constituents of some Nyasaland tea leaves and tea soils were made during investigations into the cause of a mal‐growth of tea bushes on one estate. The analytical work was supported by injection and spraying experiments in the field. Results from both investigations are given and indicate that it is unlikely that a serious ill‐balance of any mineral exists. The prime purpose of this paper is to place on record a catalogue of analytical results, since there is no previous record of this kind for Nyasaland.
