Peat is a fossil organic material, consisting of plant debris. It forms the bulk of the water saturated soils such as peat bogs.
Peat is a non-renewable resource and its extraction is highly regulated. It takes on average one century to form a 5 cm peat.
This is the traditional raw material in the development of terreaux because it has excellent agronomic qualities.
It has the advantage of having a very good water retention capacity and in air and water availability.
The different types of peat
Peat is classified into three broad categories:
- The peat which comes from the processing of peat.
- The brown peat
- Black peat which also comes from the processing of peat, but at a much more advanced stage.
To be more environmentally, it is now possible to use potting soil containing a proportion of less peat but with the same agronomic qualities. They include for example, Topsoil Brière or of wood fiber as theHortifibre.
Composition of peat
The composition of the peat depends on many essentially vegetation in which it is formed, but also the climate’Other factors such as’acidity of’water.
Peat is mainly consisting of’water and poorly decomposed organic matter (80 to 90% by weight of ashes). Only 10 to 20% of the peat consists of organic matter decomposed.
The carbon content can reach 50% of the total weight, which allowed for a long time to’use peat as fuel for heating or cooking.
