The bulk density of peat and its determination.

Abstract

The correlation between the bulk density, humification degree, and laboratory volume weight of the surface peat of virgin and drained peatlands has been studied. The difference between bulk density and laboratory volume weight was the greatest for Sphagnum and the smallest for woody peats. The Carex peats were intermediate. The correlation was also close between bulk density and the degree of humifcation. The bulk density is required for e.g. water regime studies to convery the water contents of peat measured in weight units into volume percentages.
