Compared to white peat, black peat is highly decomposed with a degree of humosity of >5 (according to van Post). The original plant structure of the Spaghnum mosses is mostly no longer visible.
We only use sufficiently frozen black peat. With increased freezing, the physical properties improve, especially the pore content, the water absorption capacity and the air volume increase. When not frozen through, black peat becomes hard after drying out and can only absorb water with difficulty.
Use of black peat in the substrate improves the buffering properties for water and nutrients. Together with clay, black peat can form the clay-humus complex, which is particularly important for the storage of nutrients and water.
We extract our black peat in this region, mainly from our own peat extraction areas that were drained long ago. This protects the environment by avoiding transport.
