文摘

Two geological granite zones were studied in a semiarid region of Brazil. Soils that overlie I-type granites had a higher fertility than those derived from S-types. Multivariate techniques properly discriminated the soils derived from different granites. Spatial distribution maps were suitable soil fertility management tools.
