For a discussion of possible calcium deficiency, see Section 5.6 on Nutrition and Water Quality. Many crops do show sodium toxicity. The toxicity guidelines of Table 1 use SAR as the indior of the potential for a sodium toxicity problem which is expected to develop following surface irrigation with a particular quality of water.
Conductivity, Salinity & Total Dissolved Solids - …
While TDS measurements are derived from conductivity, some states, regions and agencies often set a TDS maximum instead of a conductivity limit for water quality 37. At most, freshwater can have 2000 mg/L of total dissolved solids, and most sources should have much less than that 13 .
