Abstract
The aim of this research was to improve the peatland drainage for peat production, to understand peat field hydrology more accurately, to create new measuring methods for the moist layer and the water table in the field, and to test low level mole drainage. Primarily the peat type and quality determine the moisture content of a peat layer in a production field. The Sphagnum peat can maintain the moist layer 10-20 cm higher than the Carex peat, which has a smaller particle size distribution than Sphagnum peat, and the decomposition increases the difference. The density of Carex peat surface increases more easily. The Sphagnum peat field can bear the machinery even when the water table is higher due to fibrous matter content of it. With Carex peat the water table and actual capillary fringe can not be very close to the field surface because the bearing capacity of the peat is low. The unsaturated layer is thick in peat production field, and it has to thicker than in a peatland forestry, there it is called the deficit store. The ground(bog) water cooling and heating effect in summer and winter (frost) time can very easily be determined by temperature measurements. The

The ditch bottom should be under the water table in order to function well. Roughness and holes in the surface of a peat field actually enables better infiltration and filling of the unsaturated layer.}
