Soil survey, or soil mapping, is the process of classifying soil types and other soil properties in a given area and geo-encoding such information. It applies the principles of soil science, and draws heavily from geomorphology, theories of soil formation, physical geography, and analysis of vegetation and land use patterns.

Irrigation suitability studies   -This is the evaluation using the parametric method is very important to identify the irrigable and non-irrigable lands. The method is based on the topography, physical, and chemical properties of the soil without considering the social and economic constraints

Soil mechanical investigations  -Soil mechanics is the study of the mechanical properties of soils and the way that these properties affect human activities.
