This effect is <br />mainly indirect by pulling moisture out of roots and reducing the uptake of water and nutrients to affected <br />p|antnSonneemkooanbwtonictonucd1iouuo.Tipandndgeburnof|amves.s|mvvgrom/th <br />deficiencies, wilting and eventual death of the plant can occur if the salt level is excessive for the plant and <br />the problem is not corrected. To avoid plant loss in salty sites, a soll test should be done to determine the <br />soil salt level and plants selected based on their salt tolerance. <br />Soil testing laboratories will report the salinity (conductivity) of soil in decisiemens per meter (dS/m <br />(equivalent to the old measure of millimhos per centimeter). The salinity of irrigation water is typically <br />reported in micromhos per centimeter (umhos/cm) or microsiomens per meter (uS/m) <br />Conductivity is defined as the ability of a solution to conduct an electrical current, or the reciprocal nfthe <br />solution's ability to resist the current. This current is conducted by electrically charged particles called ions, <br />which are present in almost all solutions. Different solutions have different kinds and amounts ofions: <br />distilled water has very few ions, and therefore a low conductivity, while sea water has a large number of <br />ions, and a high conductivity. The greater the conductivity of the solution the higher the reading. <br />The following references on salts are available from the Colorado State University Publications on Line Site: <br />bth,:/hnnvv.cnvpcuL:nlnututo.cdn/TDA/yL.&NTSVotohlu.btod 10/23/2008 <br />Revised September 2010 (PR 08) Attachment 2.05.4(2)(d)-2-6 <br />
