What Is a Soil Hardness Tester?
A soil hardness tester, also known as a penetrometer, is an instrument that measures the physical hardness of soil or ground.
They are mainly used in the fields of agriculture and civil engineering (geotechnical engineering, etc.).
Uses of Soil Hardness Testers
Soil hardness is used as one of the indicators for soil diagnosis in the fields of agriculture and forestry. For example, if the soil is too hard when planting trees, the root system will not develop sufficiently, resulting in poor growth. Soil may have been compacted by heavy machinery, and penetrometers are useful in such cases. They are also used to evaluate the soil used as a foundation for building and road construction. Although used relatively infrequently in the field of greening, they are sometimes used in rare cases, such as sprayed greening of slopes.
