Improved probe for the measurement of soil moisture by means of tdr, characterized in that it comprises a support box constituted by a base and a cover; the base has two through holes that are crossed by two stainless steel rods, of a section coinciding with the one of said holes, and finished in a point; the inner ends to the box of the rods have a threaded area where, by means of nut and counter nut, round terminals are fixed which are connected to the end of a coaxial cable of reduced impedance, whose opposite end is connected to an ecometer; the cover of the support box has internal recesses for inserting the ends of the rods, being of matching sections; the cover and the base of the box/support are joined by screws, and the joint between them is sealed with silicone; the connection cable with the ecometer accesses the outside of the box/support laterally, crossing the joining area between the cover and the base, where a hole with a section slightly lower than that of the cable is made.
