Two different sets of bioassays were used to test different forms of nitrogen for their effect on compost-induced disease suppressiveness. In the two systems squash served as host for two pathogenic soil - borne fungi, Fusarium and Rhizoctonia. Results from both bioassay systems confirmed that ammonium nitrogen (NH4-N) markedly improved natural disease suppression properties of composted biowastes
