GEESTE, Germany: Klasmann-Deilmann has extensive extraction sites for frozen black peat in Germany. Based on the current situation, peat will remain the most important constituent of growing media in the long term. Securing sources of raw materials is therefore a high priority. In Lithuania, too, high-quality grades of peat with a higher degree of decomposition have been available for several years, these being increasingly used in substrate production. The raw-materials base for manufacturing substrates (such as blocking substrates) from black peat is thus secure into the future.
Applying our know-how in extracting black peat in Germany, we allow all more strongly decomposed peats to freeze right through in winter. The raw material is harvested in late autumn and allowed to freeze during the winter months in a layer some 25 cm thick. After drying until June/July of the following year, a very homogeneous raw peat is available with properties including excellent water capacity.
For white-peat extraction, extensive resources in Lithuania and Latvia as well as in Ireland are available to us that ensure our production sites will be supplied for decades to come. Milled peat is obtained using the latest generation of vacuum harvesters, which preserve its texture. When extracting sod-cut peat, we rely on the effective ‘cutting box’ system. Innovative techniques for drying and storage ensure the availability and homogeneity of the valuable raw materials, even in years when weather conditions are unfavourable for harvesting.
