Deep soil moisture sensor (Micro:bits)

Hi there, I want to create a multisensor remote soil monitoring station with Micro:bits. I have found a great project to start it with (link below), however, most soil moisture sensors are less than 20cm long. Deep soil moisture (50cm+) is a more important factor in many cases than shallow moisture. Has anyone seen a deeper soil moisture sensor or knows how to make one? Thanks!
