Abstract
A bark-based composition having at least 70% by volume of bark is defibrated in order to make cultivation media having water availability that is greater than or equal to 250 mL/L.
Claims11
A method of treating a bark-based composition, comprising:
- grinding and screening bark to obtain a bark-based composition comprising at least 70% by volume of bark which has a particle size of 25 mm to 40 mm;
- and
- defibrating the bark-based composition by raising temperature and compression in order to make cultivation media having water availability that is greater than or equal to 250 mL/L and a particle distribution which comprises:
- a fine fraction, corresponding to particles smaller than 100 μm, that is less than 5%;
- a medium fraction, corresponding to particles lying in the range of 100 μm to 1,000 μm, that is greater than 60%;
- and
- a coarse fraction, corresponding to particles lying in the range of 1,000 μm to 10,000 μm, that is less than 30%.

- a medium fraction, corresponding to particles lying in the range of 100 μm to 1,000 μm, that is greater than 60%;
- and
- a coarse fraction, corresponding to particles lying in the range of 1,000 μm to 10,000 μm, that is less than 30%.
