Soil ground testing is the process of analyzing soil to determine its physical, chemical, and biological properties. It is done to check the strength, composition, moisture content, pH level, nutrient content, and overall condition of the soil. This testing helps engineers decide whether the soil is suitable for construction and helps farmers understand if the soil is fertile for crop growth. By conducting soil ground testing, problems like weak foundations, poor drainage, or low soil fertility can be identified and corrected in advance.
