Field/site visit is mandatory for soil survey. The field activities during soil survey include:
- Identification of Landform
- Natural Vegetation/ Land Use
- Profile Excavation (Up to 2 Meters Depth, Where Possible)
- Soil Horizon/Layer Thickness
- Soil Colour
- Soil Texture
- Soil Structure etc.
The characteristics which are studied are relatively permanent in nature and are developed in hundreds/thousands of years. Soil samples from each horizon/ layer are also collected for laboratory analysis.
