Wood based constituents will play an important role in new growing media of the future
Horticulture and the substrate industry are undergoing a profound process of change aimed at more sustainable production. Growing media manufacturer Klasmann-Deilmann is rapidly advancing this development by utilising new, renewable raw materials in substrate blends, thus ensuring the future availability of substrates.
With the introduction of the new ADVANCED Substrate range, Klasmann-Deilmann offers modern growing media solutions, which contain 40 to 100% alternative raw materials and an optimised peat content. The future belongs to hybrid substrate blends, made from wood fibres, peat, coir as well as bark, green compost and others. These hybrid blends allow the wise use of all components and help to alsoreduce carbon emissions by 20 to 80%. However, high-quality sphagnum peat will remain the most important constituent of modern substrates in the years to come, as peat helps to use alternative materials in the substrate mix to a larger scale.

The success of these new ADVANCED recipes is underlined by the fact, that the company has tripled the amount of alternative raw materials processed in the last five years alone. In 2023, the total was 940,000 m³. This is an impressive amount in the industry and makes Klasmann-Deilmann a leading manufacturer for alternative constituents and new growing media. The company is driving this forward with vigour and especially works on securing raw material availability and substrate supply security for the coming decades. Since the international growing media demand is expected to grow strongly, these new growing media are playing an important role for the horticultural industry in future to secure substrate supply and quality.
Here, customer benefit from Klasmann-Deilmann’s extensive experience of more than 35 years in the use of alternative constituents. In additon, the company produces all raw materials inhouse in accordance with the strict RHP quality assurance system. This ensures that the new ADVANCED blends are safe and perfectly matched to their intended use, to perform well regardless of their peat content.

Linda Esters, technical consultant of Klasmann-Deilmann’s advisory team explains: “Our ADVANCED substrate range includes proven and well-established standard substrates with a balanced proportion of alternative raw materials that our customers can rely on. We provide advice on crop management, fertilisation and pH control. All our peat-reduced and peat-free substrates are nutrient-balanced to ensure simple and safe use during cultivation.” She adds: ” Our special wood fibre GreenFibre® improves the water flow in substrates and enables healthier root growth for better plant quality. Composted constituents such as our TerrAktiv® bark humus or TerrAktiv® substrate compost offer additional benefits for the plant quality: the microbial activity of substrates increases, and crops develop more healthy.”
Klasmann-Deilmann’s new ADVANCED Substrate solutions are tried-and-tested and available for any application. Linda closes: “We have been preparing for this for years and today our customers benefit from our expertise and our strong supply capability.”
