WebConductivity to mg/l: mg/l = 0.64 × EC x 10 3, or (EC in dS/m) mg/l = 640 × EC. for waters and soil extracts having conductivity up to 5 dS/m. nmol/l (chemical analysis) to mg/l: Multiply mmol/l for each ion by its molar weight and obtain the sum. There is no critical point of salinity where plants fail to grow.
WebDrainage is the primary method of controlling soil salinity. The drainage system should permit a small fraction of the irrigation water (about 10 to 20 percent, the drainage or leaching fraction) to be drained and discharged out of the irrigation project [Ref. 10].
