There is a suppressive character described for several kinds of compost against soil borne pathogens (fungi). In this experiment there was a suppression of Penicillium digitatum in vitro after addition of extracts of GFT-compost or Hoogmeerturf (a white peat). Although there are only a few sources who reports a suppressive character of peat. The suppressive character of GFT-compostextract was a result of the high bacterial activity, while the great number of fungi (i.a. Trichoderma spp.) were responsible for the suppressive character of GFT-compost. The use of microfiltrations allowed to distinguish between the biotical and abiotical factors responsible for the suppression. The autoclavation of the Hoogmeerturfextract destroyed the suppressive character; in contrast the GFT-compostextract maintain his suppressive effect after autoclavating as a result of the allelochemicals.
