- Detailed survey: in this type of survey soil boundaries are plotted first on the map by taking observations of the sample which can taken by surveyed area. In this type of geographical distribution is also taken into account.
Detailed type surveys are important because it provides all necessary information for the land use planning. Management of land use planning and formulating extension program as well as agricultural research.
- Reconnaissance survey: in this type of survey by taking observations that are made in intervals, soil boundaries will be plotted.
- Detailed reconnaissance survey: in this type of survey by using detailed method the part of surveyed area is to be plotted and will remind by reconnaissance method.
