Step 4.3 - What needs to be considered in the planning, design, cost and management of subsurface drip irrigation (SDI)?

Subsurface drip irrigation (SDI) systems involve the placement of permanent drip tapes below the ground surface to supply water directly to the crop root zone.

An example of the typical layout of a SDI system is shown in Figure 1.

This section focuses of the use of subsurface drip irrigation for pasture production, which has been the subject of a four year field experiment in northern Victoria. Basic information regarding the planning, design, cost, installation, management and maintenance of SDI systems is provided here. More detailed information specific to your circumstances can be obtained from SDI service providers and equipment suppliers.

This step will help you to assess the planning, design, cost, management and maintenance issues of subsurface drip irrigation on your farm.
