PRODUCTION: WATER TESTING
Testing your water quality can improve soil health By Dr Faranak Nourbakhsh, Senior Agronomist Water testing is critical to determine if your water source contains salts which could damage your soil, reduce crop yields or even kill your plants. The most important factors to consider in irrigation water quality are total salt content as measured by electrical conductivity (EC) or total dissolved solids (TDS), sodium level as measured by sodium adsorption ratio (SAR) or sodium percent sodium (Na), magnesium-potassium ratio (Mg/K), sodium-potassium ratio (Na/K), chloride (Cl) and boron (B). High total salt content makes it more difficult for plants to take up water and nutrients from the soil and it can lead to stunted growth, lower yields and even death of the plants.
Sodium, boron and chloride toxicities are common issues and can be easily addressed by testing the water sample. You will receive your water results along with the guideline tables and fact sheets. The SWEP team will assist you to understand the report and find the best solution for your water quality issues.
