28 The Cultivation and Preparation of Coffee 



Altitude 

 suitable for 

 Robusta 

 Coffee. 



carried out in Java, Eobusta coffee can be 

 planted from sea level up to an altitude of 3,000 

 feet. Of course nature exercises some influence 

 on the development of the trees. The trees 

 thrive well and more rapidly in low, damp 

 lands than at a high altitude. The best 

 Kobusta coffee plantations are found in those 

 districts in Java where the mean rainfall during 

 the year reaches 10 feet. The altitude of those 

 plantations varies from 1,000 to 1,500 feet 

 above sea level, and the soil consists of a deep, 

 rich vegetable mould. 



Suitable 

 Soil for 

 Robusta 

 Coffee 



The roots of the Eobusta coffee tree are 

 strong and well developed ; this can even be 

 noticed when taking the young plants from the 

 nursery. They are even stronger than the roots 

 of Liberian coffee. The roots develop in a 

 width larger than that represented by the 

 spreading of the branches, especially on the top 

 soil. If the soil between the rows were turned 

 over one would easily notice the white roots. 

 This large development of the roots denotes 

 that the plants require a light soil. Eobusta 

 coffee grows rapidly in volcanic lands and in 

 rich soils, such as in East Java. It has been 

 noticed that in hard soils the development of 

 the tree is slower and more delicate than it is 

 found in the West of Java.
