*Main parameters of each subsystem and the methods used.*

	- Select and define land key parameters to get SQI
	- Set the weights of each of the key soil parameters
	- Establish criteria and score for each key soil parameter
	- Calculating the SQI score by adding the multiplication of the score and weight for each key parameter.
	- The SQI scores are then categorized into very bad, very bad, bad, moderate, moderately good, good and very good levels.

### *6.3.3 LQI calculation and categorization*


#### *6.3.4 EQI calculation and categorization*

	- Determine the weights of PPPI, SQI, LQI and EQI
	- Calculating the OPPS score by adding the multiplication results of the scores and weights of each PPPI, SQI, LQI and EQI
	- The KIS scores are then categorized into very bad, very bad, bad, moderate, moderately good, good and very good levels.
