Abstract

The survival and establishment of a Trichoderma atroviride strain (TA) in three compost products were evaluated. Spent mushroom compost at two different maturity levels (young-YSMC and mature-MSMC) and green compost (GC) from garden wastes were enriched with a sporal suspension of TA.peat moss and potting soil were used as controls. The population dynamic of TA was estimated at different times over a period of 140 d. The potential toxic effect of enriched products on the survival of the collembolan Protaphorura armata was also investigated. All compost products were suitable for enrichment with TA. Survival was the highest in MSMC. Moreover this compost promoted the highest level of rhizoplane colonisation ability of antagonistic fungus. None of the tested products was toxic for P. armata. Among microbial, chemical and physical parameters considered the survival of TA resulted only related to N form; the fungus survive better where NH4 was prevalent on No3.
