A method is disclosed for producing horticultural or fuel peat, in which the peat is removed from a bog, the removed peat is transferred from the bog to a drying field a distance away, in which the moved peat is dried, mainly by exploiting direct solar energy, so that the peat dries due to the effect of the solar radiation and the wind, after drying, the peat is moved from the drying location to further use or storage. The drying field is a special surfaced field, essentially impermeable to water, created for drying, and the peat is spread on the field as a thin 1-15 cm layer of a high-consistency mass, with a solids content of 8-30%.
