Abstract
The form and distribution of the roots of Arabica coffee have been studied in several parts of the world and much of this work has been reviewed by Rabechault and Cambrony (1964). Excavation techniques have been used either sampling a sector of the root system (Nutman 1933a, 1933b; Franco and Inforzato, 1946) or removing the whole of it from the soil (Guiscafre-Arrillaga and Gomez, 1938). Such investigations have indicated that the spatial distribution of coffee roots of different kinds can be modified by soil type (e.g. Franco and Inforzato, 1947; Guiscafre-Arrillaga and Gomez, 1938; Nutman, 1933b, and Bermudes Espinosa, 1954); cultural practices such as mulching and irrigation (Bull, 1963); spacing (Leon and Umana, 1959); cultivation (Nutman, 1933b); tree age (Bull, 1962; Suarez de Castro, 1961); cultivar (Leon and Umana, 1961) and by overbearing (Beckley, 1935).
