Previous studies related the suppressive capability of peats to their content of carbohydrates and readily degradable organic compounds, which sustain the activity of antagonistic microorganisms. This hypothesis was corroborated by the observation that light peats, which are rich in carbohydrates, support a higher microbial activity compared to dark peats, that are consistently conducive. In this study four organic amendments (i.e. A= mixture of light and dark peats; B= peats + green plant residues; C and D= peats enriched with different micronutrients), were analyzed for a number of physical, chemical, and biological properties, including the suppression of dampingoff caused by R. solani. Disease suppression varied largely among these four peat mixtures, according to the following ranking: B.C>A>>D. Peat suppressiveness was positively related to its enzymatic activity (i.e. FDA, endochitinase, biase, glucanase and NAGase), pH, electrical conducivity, N organic, actinomycetes population density and phytotoxicity level. Only amendment B was found to be phytoxic using the Lepidium sativum test. The presence of undecomposed plant residues in B probably sustained the activity of antagonistic microbes but, at the same time, induced substrate phytotoxicity. By contrast, C suppressivity was related to the abundant presence in the mixture of Trichoderma species. Our results indicate that the combined application of peats and suppressive materials (e.g. crop residues at low dosages) is promising for container-produced plants."^^xsd:string ; skos:note "ISI Web of Science (WOS)"^^xsd:string ; pubblicazioni:titolo "Evaluation of peat mixture suppressiveness against Rhizoctonia solani."^^xsd:string ; prodottidellaricerca:prodottoDi istituto:CDS064 . @prefix modulo: . prodotto:ID88350 prodottidellaricerca:prodottoDi modulo:ID5881 . @prefix unitaDiPersonaleEsterno: . prodotto:ID88350 pubblicazioni:autoreCNR unitaDiPersonaleEsterno:ID1269 , unitaDiPersonaleEsterno:ID1479 , unitaDiPersonaleEsterno:ID1263 . unitaDiPersonaleEsterno:ID1263 pubblicazioni:autoreCNRDi prodotto:ID88350 . unitaDiPersonaleEsterno:ID1479 pubblicazioni:autoreCNRDi prodotto:ID88350 . modulo:ID5881 prodottidellaricerca:prodotto prodotto:ID88350 . unitaDiPersonaleEsterno:ID1269 pubblicazioni:autoreCNRDi prodotto:ID88350 .
