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.

This module will give you an introduction to the principles of supplying water using irrigation systems. Topics such as flow, velocity, pressure, friction loss, and power are described to help you understand, evaluate, and properly design an irrigation system.

Good irrigation system design is critical for uniform application of water to all plants in an irrigation zone.

Design is very important and cannot be covered in complete depth in this module. However, many factors related to design are covered here, so that you understand their importance to proper operation.

This module will cover best management practices for overhead irrigation management.

This module will present information to assist learners in identifying when design and installation of low volume/low pressure irrigation systems is the best management choice for irrigating nursery crops.   Specific benefits of installing low volume/low pressure systems will be discussed.
