The emission factors of production methods, combustion of peat, and afforestation are listed in Table 5.
Peat has historically been important as litter in the animal production, but the use of peat as litter within Swedish agriculture reached its peak during the 1930s.
Estimates of the area under peat extraction for previous and subsequent years are made by adjusting the 2004 value on the basis of peat production.
Replacing peat with agricultural wastes is environmentally sound because nutrients from wastes can be recycled into plant growth thus reducing fertilizer needs and environmental impacts of peat production can be reduced by reducing the demand for peat.
At the end of the 18th century, the local population learned the practice of peat production from the Norwegians and started using peat for heating.
Several studies of long-term peat records in Europe have reconstructed past changes in atmospheric lead pollution, for example, and the general cohesiveness of the results and their agreement with known historical trends in metal production exemplify the best potential of peat geochemistry as an environmental archive.
Their specific recommendations include: Growing medium - Free-draining, humus-rich, somewhat acid growing media are used for commercial production, such as a mixture of peat or leafmould and an inert material such as grit, sharp sand or polystyrene beads.
The rest of peat fuel production takes place mainly on pristine peatlands.
Nationally, the province ranks high in the production of antimony, bismuth, potash, peat, zinc, silver, and lead.
Use of peat for energy production was prominent during the Soviet Union, with the peak occurring in 1965 and declining from that point.
