Abstract
In agriculture, one of the most important issues is the extent to which the yield of high quality crops can be increased while saving labor and reducing costs. However, there are many problems in that so-called injuries of crops due to continuous cropping and other causes seriously reduce productivity. The present invention provides an apparatus and a method that can pasteurize soil using gases emitted from the engine of a tractor, while at the same time, carbon dioxide, sulfur oxides, and other acidic fumes in exhaust gas are fixed as calcium salts with slaked lime that has been applied in advance on the soil to be pasteurized, and these gaseous components can, as much as possible, be prevented from escaping into the atmosphere.
