Depending on various factors (quality of the peat, production area size, etc.), the production of milled peat can be carried out differently (Alakangas et al., 2012): 1. re-ridging (Peco) method; 2. conveyer belt (Haku) method; 3. mechanical harvesting method; 4. vacuum harvesting method. For all these methods, the first step is milling.Web
