English title: Estimation of peat yield of different peat deposit typesTiivistelmä
Preliminary regression models are produced for the estimation of dry peat yield (tons) per unit area (hectare) for different types of peat deposits with different peat thickness. The models are based on 6 500 peat samples obtained for bulk density measurements from 245 vertical peat profiles (70 virgin and drained peadands) in Finland. In general, the increase in the peat yield does not take place in 1:1 relationship with depth because average bulk density tends to decrease with peat deposit thickness. Fairly reliable estimates of the peat yield using depth and mire site type were obtained. R2 values for the eight models representing eight different groups of "mire site types" ranged from 86.0 to 95.3%. Keywords: Bulk density, mire site types, peat deposits, peat resources
