The present invention relates to a method for sterilizing soils and of the equipment related thereto. The method includes sequentially at least the following phases: dispersion into the soil of at least one compound, solid, liquid or gaseous, able to react exothermically with water and/or steam, or other substance; injection of at least one jet of water and/or steam, or of another substance, into the soil in such a way as to produce heat in the subsequent reaction with the compound. Between the two aforesaid phases it is convenient to proceed to break up the soil to favor its mixing with the compound and create the best conditions for the reaction. The equipment suitable to carry out this method includes autonomous locomotion apparatus to be able to reach the open countryside, a tank to transport water or another suitable substance and a related appendage to convey it into the soil, a second tank for the compound that is to react exothermically with water and/or steam, or, in general, with the substance transported in the first tank, and apparatus for dispensing the compound into the soil. It can also be provided with a boiler to heat or vaporize the reactant contained in the tank, as well as an agricultural tool to favor the mixing of the compound, the penetration of the reactant into the soil and the subsequent reaction thereof.
