What is Salinity?
Salinity is most simply described as the total concentration of dissolved salts in irrigation water or the soil. Almond trees are most productive on non-saline, deep, well-drained soil. However, many orchards across California are located in ‘salt-affected’ areas and require specific soil and water management approaches to prevent or mitigate salt problems and ensure continued almond tree viability and productivity.
The harmful impacts of salt can develop early in orchard establishment, resulting in water stress, nutrient imbalances and in the long run stunted trees.
Keeping Salinity in Check
Keeping levels of sodium, chloride, and boron down in your soil is an ongoing challenge with long-term irrigation in an arid climate such as California. Almond trees whose roots are exposed to excess salt may develop tissue toxicity. Leaching, rootstock selection, and soil and irrigation amendments can help with salinity management. The Salinity Management Guide for Almond Growers, co-produced by the Almond Board of California and UC Cooperative Extension, can assist growers wanting to know more about salinity management in their orchard.
