Abstract:
This publication focuses on using water analyses to choose appropriate water treatment
and water management practices for irrigated agriculture. It will help determine:
• What tests are needed to characterize water quality
• How to collect water samples
• How to interpret analytical data from a laboratory
• How to use water analyses to identify water use limitations
• How to determine the amount of salts and nutrients applied by irrigation
• Options for managing irrigation water to avoid:
— Salt accumulation
— Excess sodium and soil surface sealing
— Lime deposition on fruits and vegetables
— Emitter and nozzle plugging
— Chloride and boron toxicity
— Excessive nutrient application
