The penetration resistance reflects the load bearing capacity of the soil and is a measure of how easily roots can penetrate it. This is particularly important in agriculture and for rural and urban civil engineering. The penetration resistance is a mechanical parameter which depends on changing parameters such as the degree of moisture, the density and the strength of connection between mineral particles. The penetration resistance is measured in many measurement steps using an electronic penetrometer in combination with a data logger, whereby the data will be stored directly and analysed in the data logger. For this purpose the Eijkelkamp Penetrologger has been developed: An electronic penetrometer with integrated data logger to store and process a large number of measurement data (1500 measurements).

Penetrologger, standard set for measurement in a depth of up to 80 cm

The Penetrologger is a flexible instrument for measurements of the penetration resistance in the field.

Applications

The Penetrologger can be used in the area of agriculture and civil engineering:

• general soil examinations
• foundation appraisal
• examination into whether the soil is suitable for agricultural purposes
• examination of the growth conditions for plants
• recognition of compacted (possibly impermeable) soil layers / horizons
• examination of core growth conditions, for example, of trees in the city or in parks
• examination of artificial compaction
