As an electrical engineer I am involved in seeking methods for sensing
of moisture content of soils in fairly dry regions (wheat-growing)
without making holes or burying sensors.
We understand that sensors such as capacitive and TDR and neutron can
do the job quite well but require holes or penetration of the soil.
We seek more-mobile or airborne methods, and recognise that there
appears to be little knowledge of the limits of capacitive or
multi-frequency radar methods. Perhaps the work on these has been not
promising and thus it did not result in publication, or, it is at
pre-publication stage, or, have we missed something?
Also, I have recently heard about electrokinetic sensing especially
for aquifers, and wonder if this has been explored for moisture
mapping.
