Abstract: This research was carried out in Kazova which has a high agricultural potential in Tokat province. Tokat region is located in the northern Turkey, having a microclimate. The region has an important level of erosion problem and with this research erosion and fertility relationship and the effect of erosion on soil properties, is studied. The quantitative soil erosion amount was determined by USLE method for agricultural lands having less than 10% slope. The bilateral relations between the amount of the soil loss calculated by USLE equation in the lands of Baglar, Güzeldere, Gulpinar, Çerçi and Söngüt villages having two different landscape (toeslope, backslope and footslope). The statistical evaluations showed that there is an inverse relationship between the soil loss and productivity of the crops. A positive correlation between the soil loss amount and the sand and CaCO3 and a negative correlation between clay, pH, salt and Cu content were determined. No statistical relationship was detected among the variables which are the soil loss amount, silt, CEC, P, K, organic matter, B, Fe, Zn and Mn.
