A course that covers the design, installation, maintenance, operation and evaluation of simple irrigation systems. This course focuses on irrigation systems for row crops (eg. vegetables & cut flowers) and orchards.

There are 10 lessons in this course:

• Introduction
• Soil Characteristics And Problems
• Estimating Plant And Soil Requirements
• Drainage – drainage systems, dams, etc.
• Types Of Irrigation Systems
• Hydraulics – discharge and flow rates, etc
• Pumps And Filters
• Selecting The Right System For The Plant
• Trickle Irrigation
• Design And Operation Of Systems

Each lesson culminates in an assignment which is submitted to the school, marked by the school’s tutors and returned to you with any relevant suggestions, comments, and if necessary, extra reading.

Choosing an Irrigation System to Suit the Crop

There are many different reasons why we select one irrigation system over another. The money available to set up a system is an obvious consideration, particularly for home gardens, but the cost effectiveness and ease of operation are also of major concern, particularly in commercial situations, or in a parks department where labour costs can be high.

Flood Irrigation
Has been used in orchards in the past extensively.  This method wastes water, but once set up is inexpensive to operate, outside of the cost of water (i.e. low equipment and labour costs).
Flood does not get the foliage of the plant wet.
Flood is thorough, wetting all parts of the ground.

Sprinkler Irrigation
Overhead sprinklers can be used to protect plants from frost, as well as irrigate.  Foliage can stop even distribution of water to some parts of the ground.
Wet fruit can be more susceptible to disease.
Sprinklers are expensive to install and need high pressure (often a pump) to operate.

Trickle Irrigation
Operates on low pressure, directs water to exactly where it is required, overall uses less water than sprinklers or flood.  Does not wet fruit.  Trickle is more effective at disposing (leaching) dangerous salts from the soil.

Your choice of irrigation system will depend on:

•     Water availability (quantity and quality)
•     Water pressure
•     Labour available
•     Money available to invest in a system
•     Soil type
•     Whether disease susceptibility is higher if foliage or fruit are wet
•     Whether there is a need for frost control
