Soil Testing is well recognized as a sound scientific tool to assess inherent power of soil to supply plant nutrients. The benefits of soil testing have been established through scientific research, extensive field demonstrations, and on the basis of actual fertilizer use by the farmers on soil test based fertilizer use recommendations. Soil testing was initiated in the country in the beginning of planning era by setting up of 16 soil testing laboratories during 1955. Government of India has been supporting this programme during different plan periods to increase the soil analysing capacity in the country. The numerical strength does not, however, decisively indicate the quality and success of the programme. Planners and agriculturalists have recognized the utility of the service fully but it suffers due to inadequate scientific support in its execution.

Successful modern soil stabilization techniques are necessary to assure adequate subgrade stability, especially for weaker or wetter soils.

Soil resistivity is a key factor for determining what the resistance of a grounding electrode will be, to what depth it must be driven in order to obtain low earth resistance, and even the type of grounding system that should be designed for this location and facility. The resistivity of the soil varies widely throughout the world and changes seasonally. Resistivity is strongly affected by the content of electrolytes in the soil, its moisture content, and even its temperature. Soil resistivity measurements are therefore critical for designing and constructing a grounding system appropriate for your site and requirements.
