The field of the invention is soil sensors and in particular the sensor clement housing for the placement of a soil sensor housing in the soil. The housing having a body adapted for housing a soil moisture sensor arrangement wherein sensors are arranged within and along the length of the housing, the body having a head end and an inserted end, the body shaped so that the maximum outer diameter of the inserted end is smaller than the maximum outer diameter of the head end of the body, and the body adapted to be inserted into the prepared opening such that the outer surface of the body is in conformance with the soil forming the prepared opening along the full length of the housing. The housing including, at least one capacitive sensor, where a first capacitive element of the sensor has a maximum outer diameter, arid a second capacitive element of the sensor has a maximum outer diameter smaller than the maximum outer diameter of the first capacitive element and the second capacitive element being spaced longitudinally along the housing from the first capacitive element and located closer to the inserted end than the first capacitive clement. |
