Chloride & Salt Sensitivity in Almonds
Almonds are among several high-value crops that are particularly sensitive to chloride and salt. Continued application of potassium sources with a high chloride content or salt index can have a toxic effect, building up in the soil and contributing to lower yields, lower quality and lost income.
Sulfate of Potash (SOP) contains less than one percent chloride content, minimizing the risk that chloride can have on proper root and leaf development. Applying high chloride potassium sources can cause excess chloride to build up around a tree’s root system, blocking uptake of essential nutrients like nitrogen and sulfate that contribute to healthier, heartier crops.
Excess salt can have a number of damaging effects on crop development and soil systems, including:
- Poor germination
- Nutritional imbalances
- Seedling injury
- “Tip burn”
- Stunted root and shoot growth
- Water imbalance in the plant (drought stress)
- Reduced soil structure
- Decreased microbial activity
