On-plantation research Congo and Indonesia (1989-1992)

 

 

A detailed soil survey of a tea plantation in the East of Congo (Zaire) was conducted as part of the development of new management strategies to increase tea production. The soil survey served to reveal the major soil types at the plantation and an evaluation of the long-term weather data and soil chemical and physical properties affecting tea production. Detailed fertilisers recommendations were made to the plantation managers based on the soil and site evaluation, the genetic material (seedling tea) and the yield levels.

I undertook similar studies in West Java (Indonesia) at tea, rubber and cocoa plantations. The research was funded by British plantation owners and the results have been communicated in reports and personal communications to the owners and managers of the plantation. The research in Congo and Indonesia was conducted in cooperation with local staff and scientists.
