Irrigation with Salty Groundwater Causes Lasting Damage in Almond Orchards
Related ATTRA publication: Saline and Sodic Soils: Identification, Mitigation, and Management Considerations USDA Agriculture Research Service studies show that when salty groundwater is used to irrigate almond orchards, production can be significantly reduced and the damage to trees can last for years. Declining groundwater levels in California have led some producers to irrigate with lower-quality, saltier water. This can lead to production losses of 30%. Becoming more efficient with irrigation saves water, but can have the effect of concentrating salts at the base of trees, where they can cause surprisingly lasting damage....
