Electrical Resistivity Test: This test measures the electrical resistivity of soil to infer moisture articles, voids, and soil sort. It is actually used in environmental and geotechnical experiments. This method ends in a porous, copper-loaded layer in the drinking water Call surface area that has very little mechanical energy. https://soiltestingandanalysisbd65432.p2blogs.com/29037741/soil-testing-services-bangladesh-an-overview
