Abstract

Analyses of limestone soils under shifting cultivation, involving the growing of sweet potatoes and laros (Colocasia escalenta) for 6-8 months and a natural regeneration period of 15-20 years followed by burning of the secondary forest, showed this system to be sound. The organic-matter content of the A1 horizon shows little variation during cultivation and regeneration, and the acidity of the top soil is directly related to exchangeable-Ca levels.
