Since the beginning of the 1980ies the call by environmental NGOs and politicians for peat reduced and peat free products is growing louder. Numerous alternative growing media constituents have since then been analyzed, tested and rated as suitable or less suitable. Wood fibers, green waste composts, coir products and bark-based products have already found their market. However, for qualitative and quantitative reasons it will not be possible to do without peat as the main constituent in most growing media for the professional sector and many potting soils for the hobby sector. %U http://resolver.sub.uni-goettingen.de/purl?gldocs-11858/7242 %~ FID GEO-LEO e-docs
