<p>An apparatus (10) for sterilising a top layer of soil (12) includes a housing (14) defining a sterilisation chamber (16) having an entry opening (18) at a front end to admit the top layer of soil (12) into the housing (14) and an exit opening (20) at an opposite end so that the entry and exit openings (18, 20) are spaced by the sterilisation chamber (16). Gas burners (28) are provided in the housing (14) for heating the sterilisation chamber (16) to a temperature effect to substantially sterilise the soil (12) passing therethrough. The top layer of soil (12) enters the housing (14) through the entry opening (18), passes through the sterilisation chamber (16) where it is substantially sterilised by the heat generated by the gas burners (28) and is then returned to the ground G through the exit opening (20).</p> |
