soil testing
Checking dirt composition
Soil testing is the analysis of soil samples to determine composition, nutrient levels, pH, and contaminants.
Farmers and gardeners use soil testing to guide fertilizer decisions: The soil test showed we needed more nitrogen.
Environmental testing checks for pollutants before construction or after industrial use.
Home kits offer basic readings, while laboratories provide detailed analysis.
