10 million hectare of mires

30 % of Finlands area




Main vegetative component of peat lands are

mosses, especially Sphagnum species.




0,5 % of mires are used for peat industry







Harvested areas can be reconstructed by

Sphagnum farming







Harvested areas can be reconstructed by

Sphagnum farming



Sphagnum sp. are cultivable, renewable material

that support sustainable development


Sphagnum biomass has the same properties

as low humified moss peat and has been

successfully tested in horticultural trials

Sphagnum mosses have strong antifungal

properties against common greenhouse

disease

Mosses are acid, contain phenolic compounds

Plant growth promoting rhizobacteria (RGPR)

• Direct mechanisms

– phosphate solubilization,

– nitrogen fixation,

– degradation of environmental pollutants

– hormone production.

• Indirect mechanisms

– controlling phytopathogens by competing for resources

such as iron, amino acids and sugars, as well as by

producing antibiotics or lytic enzymes.
