www.dpi.nsw.gov.auHardness does not affect plants directly, but hardness caused by bicarbonates can affect soils, thus having an indirect impact on plant growth. A . bicarbonate (HCO3) is a soluble compound often found in saline–sodic water. While it is desirable that domestic water supplies contain less than 100 mg/L hardness, there are

Irrigation salinity – causes and impacts
www.dpi.nsw.gov.auThe effect of salt on soil Highly saline soils often become highly sodic. The ion imbalance and effect on the soil will depend on the type of salt present. Sodium and magnesium ions can destroy soil structure whereas calcium carbonate may improve soil structure (due to calcium) and increase soil pH (due to carbonate).

Soil Test Interpretation - Waypoint Analytical
www.waypointanalytical.comSOIL ANALYSIS TERMS AND APPLICATIONS The soil pH measures active soil acidity or alkalinity. A pH of 7.0 is neutral. Values lower than 7.0 are acid; values higher are alkaline. Usually the most desirable pH range for mineral soils is 6.0 to 7.0 and for organic soils 5.0 to 5.5 . The soil pH is the value that shoul d
