چکیده مقاله:
Knowledge of soil types and their properties is highly important in determining constraints and potential as well as better utilization of soils.For example clay minerals are important fractions of the soil solid phase and many soil physical and chemical characteristics are controlled by clay minerals.Too many Iranian soil surveys need to be updated. Conventional soil survey methods are expensive and timeconsuming. In Iran en general digital soil mapping (DSM) can be used for updating soil surveys. Many sampling and modeling techniques exist for DSM. The Soil Profile Database of Iran, consisting of 4250 profiles, was used to test different soil-class interpolators. The target variables were soil texture classes and World Reference Base soil groups Soil compactibility which basically depends on soil texture, organic matter and soil water content during farm machinery trafficking are major factors affecting soil conservation.
