Abstract

Understanding Salt and Sodium in Soils, Irrigation Water and Shallow
Groundwaters is a companion booklet to SWAGMANe-Whatif, a computer
model that lets you see how salts, soils, water and water tables interact.
SWAGMANkWhatif also lets you assess the effects of management
practices that you might undertake in a particular area.
This booklet gives background information to help you understand salts,
sodium and their interactions with water and soils. It explains where
sodium and salts come from, how to identify salt-affected soils, and gives
instructions on taking soil and water samples for analysis. It also gives
suggestions on how to reduce the harmful effects of salts and sodium, and
tells you where to get advice in making reclamation and management
decisions for each situation.
Managing salt and sodium affected soils, together with waters used for
irrigation, is complex. It is not possible to cover all technical aspects or
possible treatment approaches in this booklet. Instead, we have given a
simple overview of the major principles involved in diagnosing and
managing salt and sodium affected soils and irrigation waters.
It is difficult to summarise salt and sodium effects on soils and plants
without using some technical terms, so a comprehensive glossary has been
included.
