Assessing Subsoil Conditions with an ASABE Conform Vertical Penetrometer—Development and Evaluation [PDF]

open access: yesSensors, 2023
Soil is the habitat for soil organisms and associated soil physical and chemical processes. The subsoil is a large reserve of water and nutrients. Soil and subsoil are thus significantly involved in the yield capacity of a site and its resilience in the ...

Characterising Penetrometer Tip Contact during Concrete Condition Assessment

open access: yesSensors, 2022
Concrete condition-assessing penetrometers need to be able to distinguish between making contact with a hard (concrete) surface as opposed to a semi-solid (corroded concrete) surface.
