The invention relates to a method of preparing a soil conditioner by supplying air to a substantially sealed space containing a mixture of undecomposed plant-originating or animal-originating organic substance and peat, the temperature in the space rising to between 70 and 75 DEG C. The supply of air to the mixture is continued so as to keep the temperature above 70 DEG C for about 24 hours, whereupon the mixture is dried by lowering the pressure above it. The invention also relates to an apparatus usable in the method, comprising one or more reactors, one or more fans, one or more exhausters, and means for measuring temperature and air pressure and for adjusting airflow, wherein a reactor base comprises punched ventilating pipes embedded in a floor 1 to 5 mm above a casting surface. |
