Evaluation of Soil Physical Quality Index S for Some Tropical and Temperate Medium-Textured Soils

摘要: The soil physical quality (SPQ) index S can provide inconsistent designations of SPQ and has a lack consistency with other indicators for some soils. aim this study was to compare the suitability in identifying against 12 indicators, including water-release-related properties, visual examinations. This conducted on medium-textured samples taken from tropical temperate Comparisons class relationships between were used judge designation. For studied soils, classified same way as when condition optimal or degraded but not it intermediate. demonstrates that proposed critical limits are generally valid do apply all conditions. Porosity parameters water release curve more consistent than S. Our work also scores examinations have at least similar resolution (P > 0.05) evaluated. use an indicator be considered part minimum data set assessment is less viable such bulk density, porosity, examination much easily determined Therefore, too ambitious consider unique could evaluate such.
