For the professional gardener, it is important not only to work sustainably, but also efficiently and economically. Gramoflor's new gramoNUTRI-concept offers valuable support here.

A progressive reduction of peat in professional substrates towards more sustainable peat substitutes goes hand in hand with the use of a wide variety of organic raw materials. This makes the optimal composition of the substrate increasingly complex. This is exactly where Gramoflor comes in with the gramoNUTRI-concept:

Based on years of experience, the N-immobilisation can be calculated recipe-dependently for all horticultural spades and special crops as well as for different cultivation methods. This makes it possible to compensate for N loss by applying a defined amount of fertiliser.

The specific chemical properties (N, P2O5 and K2O contents) of volume builders, such as wood fibres, cocopeat, bark humus and substrate compost, are taken into account, as are the fertilisers used.

A deposit of individual cultivation conditions, or e.g. of irrigation water analyses, enables even more personal advice with the help of the gramoNUTRI-concept.

Gramoflor thus enables its customers to efficiently and economically coordinate the raw materials and fertilisers used in the substrate.

The responsible consultant can quickly carry out the calculations directly at the customer's site, so that he can offer a prompt quotation.

The gramoNUTRI-concept thus makes an important contribution to the professional, digitally supported advice of the professional gardener and to a successful cultivation process, especially in the start-up phase.

Since the end of 2021, we have been using the new and improved LIGNOFIBRE®c Xtrafine+ in our substrates. It has an extremely fine structure and thus offers even more possibilities for further peat replacement.

The new LIGNOFIBRE®c Xtrafine+ is suitable for use in all growing and propagation substrates. Even finer and shorter fibres allow for greatly improved machinability. LIGNOFIBRE®c Xtrafine+ can thus be perfectly used especially for smaller press pots and tray plates.

 Another advantage of LIGNOFIBRE®c Xtrafine+ is that it has an even higher water holding capacity than the previous LIGNOFIBRE®c Xtrafine due to its larger surface area and is characterised by good structural stability.

With this further development of the quality wood fibre, Gramoflor opens up the possibility to combine LIGNOFIBRE®c Xtrafine+ and LIGNOFIBRE® in potting substrates of medium structure and above, thus further reducing the peat content.

 Well combined - peat reduced!

With LIGNOFIBRE® coarse Gramoflor has developed a new coarse wood fibre as an additional peat substitute.

This new grade in proven LIGNOFIBRE® quality is also perfect for coarse substrates and thus for larger pots and containers. Gramoflor has recreated the structural properties of coarse white peat so that LIGNOFIBRE® coarse is an adequate alternative for it and supports structural stability in coarser substrates.

A decisive advantage of the new quality wood fiber is that it avoids waterlogging even in coarse substrates due to its good structural properties. Coupled with its good drainage properties, LIGNOFIBRE® coarse thus supports healthy root development.

It also facilitates re-wetting and promotes air capacity. At the same time, it ensures dry surfaces on the containers and thus reduces weed and moss formation on the substrate.

Gramoflor has been producing its quality wood fibre LIGNOFIBRE® from renewable and domestic raw materials in its own wood fibre plant at the factory in Vörden since 2018. The high-quality substrate raw material is produced from wood chips of certified quality through thermal-mechanical defibration.

LIGNOFIBRE® is RAL quality assured and available in 4 qualities: undyed medium coarse and dyed with medium structure as well as the very finely structured LIGNOFIBRE®c Xtrafine+.  LIGNOFIBRE® coarse completes the quartet with an undyed, coarse grain.
