It can also increase to 0.500 g cm −3 depending on the types of plant residues and their decomposition. The total porosity in the peat reaches up to 80–90% and even a bit more due to dominantly low bulk density values despite less particle density.

WebThe bulk density of peat, depending upon the ash content, decomposition degree and components of plant residues, is also low, usually ranging from 0.1 to 0.5 Mg m-3. The chemical properties of peat include elemental composition, organic components, and ash. The five basic elements of peat are C, H, O, N and S. Peat , also referred to as turf (/tɜːrf/) (a word that also refers to soil with grass distinct from peat), is an accumulation of partially decayed vegetation or organic matter.
