Irrigation Water Quality

  • Plants vary in their sensitivity to salt, boron, arsenic and other water quality parameters.
  • The season or stage of plant growth also affects sensitivity of individual plants.
  • Recommended limits for arsenic in reclaimed irrigation water are 0.5 mg/l for long-term use and 2.0mg/l for short term use.
