Quality

Quality control ensures excellence in every bale

We are known for our exceptionally consistent quality thanks to our stringent standards.

We are relentless in our pursuit for excellence in quality. Our production is run according to ISO 9001 quality and ISO 14001 environmental standards ensuring the highest standards for our products, workplaces, factories and the surrounding environment.

In addition to the quality assurance and control we conduct ourselves, we send frequent samples to external laboratories. Our professionals ensure the quality of our products during harvesting, upon arrival, during storage, in the premixing phase and factory production with various external and internal chemical and physical analysis. After testing, analysing and screening only the best peat is selected to be processed into our products.

All this means that you can trust our products to be of the best standard.

Carefully selected clean, pure and responsible raw materials from bog to bag

Kekkilä Professional substrates are made of high-quality Sphagnum peat harvested from our own bogs. Therefore, we have control and know-how through the whole production chain of our substrates from the natural peat raw material to finely tuned ready-to-use growing media.

When selecting raw material, very close attention is paid to the colour of peat, which reflects its ability to maintain structure and its degree of decomposition (von Post).

Kekkilä horticultural peat is produced on pristine raised bogs, which have not been used for agriculture or any other purpose previously. The natural plant species are predominantly Sphagnum mosses, which have adapted to wet and acidic conditions. Water levels in natural bogs are near the surface and the pH is close to 4 (soil analysis, EN 13037:1999). This ensures that the peat is free from parasitic nematodes, insects and fungi of cultivated plants.

High quality growing media does not contain weeds. This is guaranteed by constant bog management and control. The ditches on our bogs are kept clean of weeds. Samples are regularly collected during the production process and from the storage clamps in order to be sure that no weed seeds will be spread in our growing media.

Wood and sticks are removed from the raw material already at the collection site and cottongrass during the screening process. The selected raw material needs to be homogeneous in order to guarantee constant quality from bail to bail. The uniformity is guaranteed during the premixing of raw material.

Harvesting peat responsibly

Kekkilä Professional substrates are produced in Finland and Estonia. Before harvesting peat, the bog is prepared for production. These preparations always include removing the original surface layers.

Horticultural peat harvesting is done horizontally by the milled peat method. Peat particles are loosened on the surface and they are dehydrated naturally with the help of solar energy. In order to achieve the correct coarseness we extract peat as coarse as possible and screen it down according to product specifications during production.

In accurate moisture conditions peat is collected mechanically and stored in heaps, under plastic cover when needed. Peat stock piles are located on the bog area apart from cultivated fields, on the peat layer, not on mineral soils.

State-of-the-art production facilities

Our peat factories are located near our bogs. Raw material is transported to the refining factories with special trailers, which are not used for other purposes. The handling lines at the factories are kept clean and hygienic. On these lines no other material than clean peat, heat treated materials such as perlite, lime and fertilisers, are handled.

Our modern, computerised mixing process and extensive quality assurance process guarantees a high-quality end product. The correct coarseness of our substrates is guaranteed by extracting peat as coarse as possible and screening it down according to product specifications. The unique Kekkilä screening process reduces the fine dusty particles and avoids the oversized particles that complicate the filling of pots. Once tested, analysed and screened, only the highest quality peat is selected to be separated according to peat type, degree of decomposition and coarseness.
