Frontiers | Water Table Fluctuation in Peatlands Facilitates …
Consequently, if Sphagnum biomass production is in future to be significantly enhanced, serious consideration must be given to managing a stable water table levels within the Sphagnum farm peat fields. Our study clearly indicates that optimal biomass production will only be achieved under a regime of limited water table fluctuation.

In the deeper soil layers, pores are significantly smaller with less interconnection, which leads to more restricted flow and greater tortuosity. ...

Effects of water table position and plant functional group on plant
Sphagnum mosses are a primary driver of peat accumulation due to relatively slow decay and high annual rates of production (Johnson and Damman 1991). Sphagnum mosses are ectohydric, meaning they rely on external transport of water via capillarity, and are sensitive to periods of water stress (Proctor 2000 ; Glime 2007 ).

Effect on Chemical and Physical Properties of Soil Each Peat …
Peat moss is an organic substance corroded by sphagnum moss and has a pH of 3.0–4.0. Elemental sulfur is sulfated and oxidized by the action of bacteria to become sulfuric acid. These biological factors can alter the soil environment. Blueberries require soil with a pH of 4.5–5.2 and high organic matter content.
