The mountain soils were Utisols and Inceptisols, while the soils of the other three regions were Oxisols. The study assessed the soil components, mineral composition, pH, phosphorus fixation, potassium availability and buffering capacity, cation exchange capacity (CEC), effective cation-exchange capacity (ECEC), and base saturation.text/plainen-USIn CopyrightSoil organic matterSoil managementSoilSoil nutrientsSoil fertilityMindanaoThe PhilippinesSoil developmentSoil propertiesPhosphorus (p) fixationPotassium (k) availabilityCation exchange capacity (CEC)Base saturation (bs)TopographySoil analysisCrop productionOxisolsUtisolsInceptisolsAlluvial terraceLower footslopesUpper foot slopesMountainsEcosystem Field ScaleAbstractCopyright 1999 by the Soil Science Society of America
