Irrigation and soils
Soils are a crucial component of irrigation management. Knowledge of soil and its relationship and behaviour to water will help produce better yields and reduce costs. Below are a series of links and resources on this issue.

- Inappropriate irrigation practices can lead to a situation where soil salinity levels increase to levels unfavourable for optimal crop growth. This section provides irrigators with options to manage their soil’s salinity levels.
- Irrigation salinity
- Salinity training manual (Please note this is a large file and may take time to download)
Measuring salinity (groundwater and soil)
Salinity meters – maintenance and conversion tables
Scheduling for salinity mitigation
- The appropriate management of nutrient application associated with irrigation is vitally important for a number of reasons, including maximising the benefits to be gained from the application of an expensive commodity, and minimising the negative effects of high nutrient loads within groundwater.
- Nutrient movement through SA soil
Fertigation - The application of fertilisers (nutrients) through a pressurised irrigation system
