The aim of this study is to determine land quality index of agricultural fields in Samsun province using parametric approach according to some physical and chemical properties of 889 soil samples from 0-20 cm soil depth using global positioning system and to analyze effects of experimental factors on land quality index (LQI) using 24 factorial designs. Soil depth, slope, texture, soil reaction, electrical conductivity and organic matter were determined as experimental factors. In order to determine experimental factor and their significance Minitab16 statistical software was used and a recreation model was suggested for Samsun region. In addition to that, in the result of this study it was represented as about 98.96% for the results of LQI of Samsun selected 889 points using 32 samples.}, number={2}, publisher={Ondokuz Mayıs Üniversitesi}
