High Sodium, excess salinity, high bicarbonates are all big problems when irrigating crops.

Knowing the chemistry of you water will help you better manage the water and your soil.

The sodium adsorption ratio (SAR) for example, is a critical calculation for assessing the suitability of irrigation water and is based on relationship between sodium, calcium and magnesium in your water.

Water with a high SAR can quickly degrade soil structure – but this can be avoided, with the use of gypsum and planting crops more resistant to saline waters - click here to see salt tolerant crops.
