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.

Salinity Management

  • 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.

Nutrient Management

  • 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.
