In the first week of September ECN has published the 'Guidelines  for Use of Quality Compost in Growing Media' as Part D of the ECN QAS Quality Manual. These guidelines set out suggested minimum quality criteria for compost when used as a constituent in horticultural growing media.

They apply to composted material prior to blending with other substrates and not the final growing medium mix. Additional quality criteria may therefore be required depending upon the intended use of the growing medium, especially if used in professional applications. Due to the wide range of potential growing media products, these guidelines are not intended to be prescriptive; instead they set out desirable quality criteria that are recognised as being important in the formulation of horticultural growing media.
