Techniques for Sphagnum restoration in Canadian peatlands

table. The peat remaining in the bog after harvesting is more decomposed and is subject to shrinkage, oxidation and compression due to exposure from anaerobic to aerobic conditions (Price 1996). The more decomposed peat layers also have smaller pore spaces, which reduce the available water, which is required by Sphagnum moss. The water table on ...

The trembling earth: Sphagnum or peat moss

the thin greenish top living layer (10-12 inches deep) is the acrotelm, through which water can move quite rapidly, and which helps to protect the layer beneath; the bottom thicker layer of peat is called the catotelm. This brown dense layer contains pieces of sphagnum and other plants remains that are compressed by the weight of the water and ...

Sphagnum Peat Moss | Van Egmond Potgrond

Sphagnum Peat Moss is a relatively young white peat, originating mainly from the Baltic States. The peat moss is extracted from the top layer of a peat field, is lightweight and pale in colour. It has excellent water absorption and retention properties. Low acidity (low pH) and zero nutrient level are characteristic for Sphagnum peat moss.

Sphagnum mosses on cutover peat: Moss layer structural ...

The structure of Sphagnum moss communities strongly affect their ability to retain and redistribute water in a peatland ecosystem. This moss structure varies by species, and within species depending on certain abiotic factors (e.g. shade). On cutover bogs mosses that have regenerated, either spontaneously or through managed restoration, may develop a relatively …

Sphagnum Moss vs. Peat Moss - Garden.org

Jul 27, 2014· Over time the sphagnum moss dies and is over-grown by new sphagnum moss. This is repeated over and over, and after hundreds or even thousands of years these many layers of dead sphagnum moss form a bog. This layer of dead, compacted moss is now called peat moss. Peat moss is saturated with water, and can be up to 70% water.

The peat moss retains up to twenty times its weight in water so I figure even though the stone will dry out fast the peat moss will retain enough moisture for the roots. Anyway, the stone has a ph of 7.0 and the ...
