Soils

Due to the influence of microclimates in the basin, several types of soil occur. In the pedological characterization of the agro-ecological units, Dinis and Matos (1986) in "Os Solos da Ilha de Santiago" general study of Faria (1970), identify, according to the climatic zones and the main geomorphological situations, the various types of soil (Table 2).

Tables 3, 4 and 5 summarise the various characteristics of 20cm deep soil samples in three bioclimatic zones of the basin.
