Soil Testing Services

We provides soil testing services.
Sigma analyses soil samples for ph, soil salts and nutrient levels in the soil for identifying its suitability for agriculture, presence of metals, organic matter, resistivity, crop nutrient requirements, fertilizer recommendations to get maximum productivity.
Soil testing solutions offered help in testing overall health of the soil. Among many tests, one that is done includes testing of chloride content. Here, the negative effect of chloride concentration as present in soil on corrosion of reinforcing steel was done through measuring corrosion potentials as well as corrosion current density in soil testing. In the situation pertaining to presence of concrete in contact with soil can lead to corrosion of embedded reinforcement. Further, chloride levels in soils are also undertaken for checking of soil adjacent to concrete is suitable. The test method employed is meets is:4032-1985. Apart from this, other tests that are done for soil testing include:
electrical resistivity –
it helps in determining if inferiorcheaper substance has electrical resistivity of soil
this is performed through testing soil physical properties like its structure, fluid composition and water content
it is also an attractive tool for describing subsurface properties without digging
