Table 12: ECe Values of Soil Salinity Classes provides assessment of EC e values as referred to byHazelton, P. and Murphy, B. (2007). These relationships are largely based on chloride salts.TABLE 12: EC e VALUES OF SOIL SALINITY CLASSESClass EC e (dS/m) CommentsNon-Saline (NS) 16 Only a few very tolerant crops yield satisfactorilySource: ‘Site Investigations for Urban Salinity’, Department of Land and Water Conservation (2002)The assessment of the exchangeable sodium percentage (ESP%) is based on rating referred to byDepartment of Land and Water Conservation (2002) ‘Site Investigations for Urban Salinity’ and iscontained in Table 13: ESP Rating for Sodicity.TABLE 13: ESP RATING FOR SODICITYESP%Rating15 Highly SodicSource: ‘Site Investigations for Urban Salinity’, Department of Land and Water Conservation (2002)Chlorine is present in soil as chloride ion (Cl) and is a component of many primary and secondaryminerals and common salt (sodium chloride). High levels of chloride generally contribute to highelectrical conductivity of the soil solution. Chloride levels between 180 – 600mg/kg in loamy soilsand between 300 - 900mg/kg in clay soils are considered slightly elevated for agricultural productionand can cause chloride toxicity in some plants. The Australian Standard 2159: 1995 Piling – Designand Installation provides an exposure classification for steel piles – piles in soil in Table 6.5.2 (C) ofthe standard. The exposure classification as provided in AS 2159 is provided in Table 14: ExposureClassification for Steel Piles - Piles in Soil. Note that 1ppm = 1mg/kg.TABLE 14: EXPOSURE CLASSIFICATION FOR STEEL PILES - PILES IN SOILpHChlorides (Cl) in soilppmIn high permeabilitysoils (i.e. sands andgravels) which are ingroundwaterIn low permeability soils(i.e. silts and clays) or allsoils above groundwater>5
