What is the difference between block peat and milled peat?

Block peat refers to the machine extraction of peat blocks by white peat cutting machines. The peat blocks or sods must dry in the field for at least one year in order to reduce the moisture content from 90 % to about 40-60 %. In the factory, the peat blocks are crushed and sieved into various fractions.

Harvesting milled peat requires milling a few centimeters of the peat fields, which are leveled and drained beforehand. The loosened layer is turned repeatedly. The dry, loose peat is then pulled or shoved together into a small pile and afterwards vacuum harvesters collect and transport it to larger stockpiles. Although milled peat is cheaper to harvest than block peat, it generally has a larger amount of fine granulation.
