I want to understand better the usage of parameters on soil quality index determination.
An interesting question , we need to study to define the minimum dtaset required to define the rhizopshere of a crop, though there are some common soil properties to defne the soil quality index with respect to a crop...since soil quality is a functionality parameter ...
Dear Leo,
depending on the land use and local environmental conditions number and relevance of selected soil indicators may differ; see some documents and web pages:

Three relevant PDFs are attached for your perusal. You may find them useful in selecting functional parameters for soil quality index of your soils' area. Good day!
Soil quality index (SQI) is commonly measured to assess the soil's capacity to function, and it varies from soil to soil. The following soil parameters can be used: physicochemical such as texture, SOM, and pH; biological such as soil respiration and microbial biomass.
Monitoring the changes in soil quality indicators allows for understanding trends of soil quality. Many soil attributes can be used as indicators of soil quality. However, these are often highly correlated among themselves making it difficult to interpret the significance of changes in selected soil quality indicators. The soil quality indicators should be selected based on the scale problem. Indicators can be adjusted to match the scale of assessment or can be expanded to larger scales using various statistical procedures. A minimum data set consisting of a set of soil attributes including soil chemical, physical and biological properties are selected to assess soil quality. The fitness of indicators used for soil quality assessment varies spatially depending on land types or land use, soil function and soil-forming factors.
The following two publications should be very helpful to you.
