The content of peat in substrates may not exceed 80% for seedlings and 50% for trees, herbaceous and ornamental plants. Exceptions are possible for crops, that require a low pH. Purchased composts, peat substitutes and additives must be examined with regard to their environmental compatibility and, in particular, to their pollutant content. (BIOLAND standards 5.8.6., 5.8 Ornamental Plants, Herbaceous Plants and Woody Plants, 5.8.6 Soils and Substrates)


The BIOLAND standard is slightly more detailed as the EU Regulation 2092/91, where the the use of peat in horticulture is not restricted. Purchased composts must not exceed the contents in heavy metals, laid down in the Annex II A. There is no requirement to examine the environmental compatibility of the components of substrate.


To avoid the escessive exploitation of moor lands and to avoid contamination with harmful substances.
