Learners will:

• describe and conduct procedures for collecting irrigation water supply samples for preliminary analyses on site for electrical conductivity and pH determination and prepare samples using any required precautions necessary for sending samples to commercial analytical laboratories for water quality analyses.
  

• enter requested information and identify specific water quality tests to be performed on analytical laboratory work order forms which accompany water samples submitted for analysis.
  

• identify and describe mineral water quality impurities which frequently require treatment for use as container crop irrigation supplies.
  

• describe problems associated with individual mineral and water capacity factors.
  

• discuss treatment procedures for meditating problems associated with excessive mineral content, pH, EC, sodium chloride, SAR, carbonates and bicarbonates or other water quality impurities associated with irrigation supplies.
  

• calculate the irrigation water volume required for daily irrigation by the nursery.
