摘要：Soil resources monitoring and evaluation of its status leads to specific and systematic plans related to agricul tural production . By providing the soil fertility map in terms of land status, nutrient for cultivation by farmers would be determined. This leads to the correct application of fertilizers to achieve optimal conditions in productivity of the soil resources . In this study, evaluation of soil fertility using geostatistical techniques and fuzzy logic in a Geographic Information System was conducted for a part of agricultural land of Amol city , Iran . In field studies, 201 points from 0 to 30 cm depth were sampl ed . After laboratory analysis, values of soil available phosphorus, available potassium , organic matter, Electrical conductivity (EC) and soil reaction (pH) were measured followed by statistical processing of the points interpolation using Kriging model in the GIS environment . Then, for map providing, a fuzzy membership function defined according to soil parameters critical levels. Finally, to achieve the final map the fertile layers were combined
