Values for electrical conductivity, calcium and magnesium were in the same order as total harness. Sodium levels were also highest in well samples ( 26mg/l), while the mean zinc levels were less than 0.29,g/l except for samples from glasshouse roofs which had a mean of 0.40mg/l. Due to lack of sufficient samples a valid inter-county comparison could not be made. However, there were large differences in the total harness of water from North and South County Dublin, with values of 198mg/l and 63mg/l (CaCO3) respectively.||Type of material:||Journal Article||Publisher:||An Foras Talúntais||Journal:||Irish Journal of Agricultural Research||Volume:||20||Issue:||1||Start page:||108||End page:||112||Keywords:||Water composition; Hardness values||Language:||en||Status of Item:||Peer reviewed||metadata.dc.date.available:||2015-09-08T16:01:38Z|
