In the past WOSSAC has highlighted the early work of American soil specialists in the tropics. A blog posts for Hawaii, (WOSSAC website, May 2025 “Soil Map of the Hawaiian Islands”) drew attention to a comprehensive soil and land evaluation survey carried out with technical assistance from the USDA.
Most recently a coloured soil map at scale 1:800,000 covering the whole island of Cuba dated 1928, and prepared by the US Bureau of Soils, working with the Tropical Plant Research Foundation, based in Washington, has been scanned by WOSSAC. The surveyors are Bennett, H.H, and Allison R.V. This attractive map has a comprehensive soil legend on the face of the map, and in addition is accompanied by a sheet setting out a detailed soil classification described as a ‘Key to the Principal Soils of Cuba’. The map and key form a part of a report entitled, ‘The Soils of Cuba’, a handsome hardback volume of 410 pages sponsored by the Cuba Sugar Club, Havana. The WOSSAC archive holds an original copy of the book/report (WOSSAC ID. WOSSAC ID 41158) and its accompanying map and classification key (both at ID. WOSSAC ID 45005). Both the map and the soils key sheet are fragile and have been scanned and then archived WOSSAC facility at Cranfield University.
This 1928 work builds on the first comprehensive systematic soil survey in Cuba undertaken in 1904, also, by Bennett and Allison, in cooperation with the US agencies. This pioneering initiative provided the background for the 1928 published book and accompanying map.
This systematic work constituted a landmark in the history of soil science in the Caribbean region and provided a first step in documenting Cuba’s soil diversity and agricultural potential. Soils were classified according to their inherent characteristics, rather than by external relationships as was common at the time. This approach used in Cuba was considered, to be innovative, and the first real survey of this kind across any large area within the tropics. The soils were classified into Families, Series and Types, and in the text, the Soil Series identified (some 103 in total) are comprehensively described, including discussions on the results of chemical and physical analyses. The different related Series are grouped into 17 Families, based on geology. The soil map shows the distribution of 80 soil types, mainly soil series associations, which are described in the legend.
This exhaustive reconnaissance study of the soils of the Island was intended as a basis for the improvement of the agriculture sector, especially sugar cane production. Cane has been grown since the first half of the 16th century and has been long recognized as the main agricultural activity of Cuba. Production reached a climax following the first World War and by 1925 Cuba produced 25% of the world output of cane sugar. However, this was achieved by bringing virgin land into extensive cultivation and reducing forested areas. Substantial areas were taken into the production of cane and subsequently the crops failed. Despite the island being regarded as well adapted to the growth of this crop, little was known of the suitability of certain soils to the growth of cane and other tropical crops, particularly on virgin land.
These concerns prompted the producers to band together and sponsor this ambitious mapping and reporting endeavor. This comprehensive legacy inventory and mapping, therefore, became an indispensable reference document for the cane industry at the time; also, for future planning of the agricultural sector in Cuba; and finally offers a glimpse of land use in Cuba in the 1920s.
