<p>A comminuted or particulated growth substrate is produced by extracting peat blocks from bog and drying these blocks to a moisture content of 10 to 30 %; the blocks are thereafter compressed into a volume of 1/3 to 1/10 of their initial and the particulated growth substrate is prepared from the compressed blocks by cutting or frasing. The method according to the invention enables one to prepare a filling material for pots which has the desired ideal physical properties for paper pots. When using the product in a dry state for the filling of pots it flows easily even into a small pot. After wetting, the product in the pot swells quickly, thus giving a tight filling. The same filling technique may be used also for other pots and cultivation troughs.</p> |
