from drained peatlands by direct vacuum harvesting (Fig. 1). Traditional cutting of peat into large (typically 25 by 10 by 10 cm) sods (Fig. 2), which are then air dried, is still extant because sods may be a better source of large particle size fractions than milled peat. Sod peat is less dusty and has a higher air content than theWeb
Vacuum peat harvest is somewhat similar to green Sphagnum harvest, except it removes the already-dead Sphagnum plant that has become peat. When opening a new peatland for harvest, the operator will remove the live plants and topmost surface and store it nearby for use as a reclamation material. Then, on an annual basis, the peat …Web
