Method for one-time or continuous nondestructive determination of the penetration and leaching process of conductive phases in materials, wherein the conductivity of the material to be examined is measured in thin superposed layers in that, after applying voltage to pairs of oppositely disposed conductor paths associated with these layers, the current flow through separate layers of the material is measured and an increase of the current in increasingly deep layers indicates the advance of the front of the penetrating phase.

Method and apparatus for determining the penetration and leaching

Apparatus for the continuous measurement of increases and decreases in moisture condensation at soil and/or plant surfaces, including a dew measuring probe composed of a sample material, a radiation source disposed underneath the probe and emitting beta particles, and a beta particle detector disposed in alignment with the radiation source and on the opposite side of the probe from the source.
