soil test
Dirt fertility check
A soil test is an analysis of soil composition, typically measuring pH, nutrient levels, and organic matter content.
Gardeners and farmers use soil tests to determine what amendments their land needs: The soil test showed we needed to add lime.
Environmental soil tests may check for contaminants like lead or pesticides.
