Abstract
It is necessary to develop 'a sound advisory service for the efficient use of fertilizers and soil amendments in the coffee crop based on soil and plant 'analysis. This can only be done effectively by undertaking extensive field calibration trials together with longer-term bench mark site trials. An approach is outlined and problems specific to the perennial coffee crop are discussed. The problems of leaf sample ¥variance are referred to in the light of recent research work and some figures are presented and discussed which emphasize the order of magnitude of variation that can be expected with soil samples taken for advisory purposes.
