A soil testing lab plays a crucial role in assessing the health and composition of soil for various applications, including agriculture, construction, and environmental studies. These labs analyze soil samples to determine key properties such as pH, nutrient content, texture, and contamination levels. The results help farmers optimize crop production, enabling them to make informed decisions about fertilization and irrigation. For the construction industry, soil testing ensures the stability and suitability of the land for building projects. Overall, soil testing labs provide valuable insights that support sustainable practices and help maintain soil health and safety.
