The present invention relates to a method for sterilising soils and of the equipment related thereto. The method comprises 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 favour its mixing with the compound and create the best conditions for the reaction. The equipment (10) suitable to carry out this method comprises autonomous locomotion means (1) to be able to reach the open countryside, a tank (2) to transport water or another suitable substance and a related appendage (5) to convey it into the soil, a second tank (3) for the compound that is to react exothermically with water and/or steam, or, in general, with the substance transported in the first tank (2), and means (4) for dispensing the compound into the soil. It can also be provided with a boiler (6) to heat or vaporise the reactant contained in the tank (2), as well as an agricultural tool (8) to favour the mixing of the compound, the penetration of the reactant into the soil and the subsequent reaction thereof. <IMAGE> |
