Prevention to high salinity 

• Use low-salinity irrigation water:  

• If possible, test your irrigation water for salinity and use water with low salt content. 

• Consider rainwater harvesting as a source of low-salinity water. 

• Improve drainage:  

• Ensure that your soil has good drainage to prevent salt accumulation. 

• Amend heavy clay soils with organic matter and coarse sand or perlite. 

• Install drainage systems if necessary. 

• Avoid over-fertilizing:  

• Use fertilizers sparingly, as excess fertilizer salts can contribute to soil salinity. 

• Use slow-release fertilizers to minimize salt buildup. 

• Mulching:  

• Mulching around the base of the trees helps to retain moisture and can reduce the amount of evaporation, which can lead to salt concentration. 

2. Remediation: 

• Leaching:  

• Leaching involves flushing excess salts from the soil by applying a large amount of water. 

• This is most effective in well-drained soils. 

• The amount of water required for leaching depends on the soil type and salinity level. 

• Gypsum application:  

• Gypsum (calcium sulfate) can help to replace sodium ions in the soil with calcium ions, which can improve soil structure and reduce salinity. 

• Gypsum is particularly effective in sodic soils (soils with high sodium content). 

• Foliar washing:  

• If salt deposits are noticed on the leaves, rinsing the leaves with fresh water can help to remove the salts and prevent leaf damage. 

• Planting salt-tolerant cover crops:  

• Planting cover crops that are tolerant of salt can help to improve soil health and reduce salinity over time. 

 

Achieving the Correct pH: 

• pH Testing:  

• Use a soil pH test kit to determine the pH of your mix. Citrus trees prefer a pH between 6.0 and 7.0. 

• pH Adjustments:  

• If the pH is too high (alkaline), you can add sulfur or acidic fertilizers. 

• If the pH is too low (acidic), you can add lime. 

• Many citrus potting mixes will already have the correct PH balance. 

4. Blending the Mix: 

• A general guideline for a good citrus potting mix is:  

• 50% base potting mix or garden soil(for in ground planting). 

• 20% perlite or coarse sand. 

• 15% Coco Coir or peat moss. 

• 15% Pine bark fines. 

• Mix all the components thoroughly to ensure even distribution.

If the pH of your soil is greater than 7.5, then the soil may contain a large amount of free calcium carbonate. Wood ash will raise the soil pH and make the soil more alkaline.
