The impact of water quality on biosolids salinity
and acidity, biomass production and metal extraction was assessed
by comparing means (Students t-test, IBM SPSS Statistics 20) between
the fresh water treatment (FW) and the medium irrigation
treatment (MI). The impact of additional winter flooding on biosolids
salinity and acidity, biomass production and metal extraction
was assessed by comparing means (Students t-test, IBM SPSS Statistics
