Select – special requirements, individual solutions
Our Select product line is geared to achieving an individualised, ideal substrate blend from a wide range of possibilities. The needs of a specific crop are taken into account, as are technical, climatic and geographical factors. Select line substrates can be perfectly adapted to the site and conditions at a given nursery.
Dialogue with our customers
In dialogue with the customer, our specialists choose the right components and suitable combinations of nutrients, determine the optimal blend ratio and ensure trouble-free production. After all, equipment and production resources in a nursery will only work together seamlessly if the substrate combines the different elements into a perfect whole.
In many markets, a country-specific range of growing media has also emerged under the Select line. These ranges include substrates that are ideally tailored to the specific requirements of particularly popular crops in a given region.
Examples of uses
With a very small percentage of fine material, blends of stable white-peat fractions and selected admixing agents achieve optimal capillary water distribution, especially when using drip irrigation and ebb-and-flow systems.
To assist the blue coloration of potted hydrangeas, specialist substrates are boosted with aluminium sulphate and their pH value is adjusted accordingly. Individual solutions are also possible for potted chrysanthemums and potted roses, as well as for Primula obconica and many other plants.
For cyclamens, stable clay granules with high exchange capacity for nutrients are available. Besides reinforcement with a high-potash fertiliser, the addition of antagonistic Fusarium strains to suppress cyclamen wilt is also possible.
Coarsely fibred structures that ensure drainage are the basis of all nursery stock substrates for container use. The requirements of rhododendrons can be met by adjusting the substrates through the addition of sod-cut peat and wood fibre. In the case of special substrates for container roses, the buffer capacity is increased by adding clay.
Potting substrates for ericaceous plants are adjusted by, for example, adding fractionated sod-cut peat. The proportion and structure of the sod-cut peat is chosen according to the size of the pot and the growing method, so that air capacity and drainage can be optimised for even a 9 or 10 cm pot size. The pH value is adjusted by using fast-reacting lime and high magnesium content.
The substrate water content can be precisely adjusted. The result is a substrate perfectly suitable for any press pot machine as well as stable press pots for automatic planting machines.
Tray substrates of the Select line consist of finely screened black peat and white peat types of different origins. The ratio of black to white peat in these substrates is adapted to the specific season, irrigation water and crop. The addition of a wetting agent ensures easy wettability of the substrate.
In order to manufacture very finely structured propagation substrates for trays with extremely small cell sizes, the raw material is graded with a flip-flow 8 mm screen. This ensures that the products can be processed without difficulty on all filling lines. In order to avoid undesirable effects through storage, all propagation substrates are shipped directly after manufacture.
Full fertilisation programmes are available, combining easily with liquid fertilisers chosen by the nursery. All fertiliser options are free of genetically modified material and contain, for example, horn powder and shavings from BSE-free countries as well as potato protein or fermented residues from corn oil production.
The production method for organic substrates is subject to inspection and control by an independent EU inspection body. Organic substrates conform to the guidelines and requirements of organic growers’ associations in Germany, Austria and Switzerland.
Select – the supply forms
The volume of all products by Klasmann-Deilmann is measured in accordance with European standard EN 12580, which specifies the procedure for calculating the volume of growing media and other peat products which are delivered either in bulk or packaged. As a general rule, the figure stated refers to the volume at the time of production.
