The median starting soil metal concentrations for each aged treatment (n = 3).

Concentrations are from soil samples taken on 7 February, 2013.Values in the square brackets represent minimum and maximum.0 yrs, 5 yrs and 10 yrs signify the respective age groups.11Concentrations for 0 yrs are applicable to the synthetic stormwater and potable water irrigated zero year treatments (i.e. the composted manure soil with no sediment addition used for the SW 0 yrs and Pot 0 yrs).aPot = potable.bSW = synthetic stormwater.cEC = electroconductivity.dTN = total nitrogen.eTP = total phosphorus.The median starting soil metal concentrations for each aged treatment (n = 3).
