The aim of this study is to determine the soil quality index in a
watershed. For this purpose, the watershed was divided into 500x500m grids, and
138 samples points generated. Totally 276 soil samples (disturbed and
undisturbed) were collected in order to determine soil properties included
grain size distribution, aggregation rate, aggregate stability, organic matter,
mean weight diameter, porosity, field capacity, wilting point, pH, electrical
conductivity, bulk density. These properties were used as indicators, and the
Analytic Hierarchy Process (AHP) was used for weighting and scoring the
indicators, and determining soil quality index (SQI). The SQI showed
differences along the watershed.
