The book "Agricultural Salinity Assessment and Management", American Society
of Civil Engineers, 1990, is, I believe, the most current and comprehensive
reference on salinity in agriculture.
Their address is:

Finding salinity from conductivity (Romain Gagnon <RGagnon@smartrain.com>)
Date: Mon, 11 Nov 1996 10:08:01 -0500
From: Romain Gagnon <RGagnon@smartrain.com>
Subject: Finding salinity from conductivity
Hello everybody !
We are manufacturer of an innovative irrigation control system based on soil
moisture content (see our web site for more info: http://www.SmartRain.com).
Our sensor also measures soil conductivity and we wish to correlate it with
soil salinity if possible.
I wander if anyone could help us with the following problem:
To our knowledge, the easiest and standard way to measure soil salinity is
to measure its electrical conductivity.
Unfortunately, measuring electrical conductivity is not always obvious.
Using direct current (DC) will polarize the electrodes of the probe used and
plate them. Using a too low frequency alternative current (AC) is better
but will do the same with time. On the other hand, using a too high
frequency current will create dielectric losses and increase the
conductivity over its normal ionic level. Also, we have experimentally
observed that the conductivity level is actually very dependant on frequency.
Therefore, what is the optimal frequency if any ?
The second part of the problem arises from the fact that conductivity is
also very much dependant on soil moisture. Some manufacturers even use
conductivity to measure soil moisture !!!
Therefore, what is the ideal soil moisture level at which conductivity must
be measured in order to correlate with soil salinity ? We heard that
laboratories were using field capacity ? Also, do you have any equations or
empirical relationships relating soil salinity and soil conductivity at a
certain frequency ?
Thank You in advance for your help.

references about water salinity (Francesca Di Pietro <francesca.di-pietro@jrc.it>)
Date: Wed, 13 Nov 1996 12:26:17 +0100
From: Francesca Di Pietro <francesca.di-pietro@jrc.it>
Subject: references about water salinity
Hello to everybody,
thank you for taking the time to read this message.
I am working on conflicts in resources allocation, and particularly in water
resources allocation. One of the most important environmental problems
emerged in my case-study, a mediterranean basin in Sicily (Italy), is the
salinization of the river and ground water, due to the over-exploitation of
the water supply.
Thus I am looking for references on water salinization: can you help me ?
Thank you for your assistance. I hope I can return the favour one day.

Greetings from sunny Riverside Ca.
A comphrensive source of information about salt effects on water quality is
Volume 25 (3) of the journal Agricultural Water Management published in
1994. This special issues contains four papers: Irrigation - a blessing or a
curse (J. van Schilfgaarde), Irrigation and global water outlook ( H.
Bouwer), Using water of marginal quality for crop production: major issues
(J. Shalhevet) and Irrigation with poor quality water (J. Oster). All of the
articles include extensive literature citations and the topics covered are
appropriate to water quality impacts on water use by agriculture and also
municipalities. At 05:21 AM 11/13/96 -0600, you wrote:

hallo,
I want to ask information about results obtained by field/laboratory
application of physically-based models for predicting salinity and sodicity
(model used, performance of the model,etc.). I want to ask about models for
predicting salinity and sodicty accounting for bypass flow.
thank you in advance, Giuseppina Crescimanno

Introduction (staylor@nor.com.au (Scott Taylor))
Date: Sun, 1 Dec 1996 14:18:58 +1100
From: staylor@nor.com.au (Scott Taylor)
Subject: Introduction
As sensibly suggested by Jose Antonio Cuchi-Oterino, the following is my
introduction for list members...
Who I am...
Scott Taylor
I have a BSc in soils/geomorphology with major studies in land management,
plant and animal biology, ecology and climatology from Macquarie University
- Australia. I am currently a land resource planner with the NSW Dept. of
Land and Water Conservation.
What part of the world am I from...
Australia, specifically the sunny north coast of beautiful New South Wales.
- Why am I interested in salinity-l...
I was responsible for mapping salinity and other forms of land degradation
in the central west of NSW and during the process authored an extension
guide on salinity for our field staff. This has been reprinted in both its
first and second editions. We have a developing salinity problem which is
predominantly centred in our Mediterranean climate areas in the south of the
state. We also have problems with sodic soils in many areas. As a resource
planner, I am interested in integrated management of all forms of land
degradation on a catchment (watershed) basis - salinity offers a potent tool
to increase interest in treating land degradation in this integrated way as
the causes and effects are widely separated.
- What your experience with salinity problems are...
My mapping, experience in resource assessment and planning and creation of
the salinity books.
- Your specific questions or topics that you would like to see discussed...
Decision support systems for treatment; current work in development of EC1:5
to ECe conversion factors; terrain, climate and risk map models, breaking
news on salinity and sodicity, communication with other resource managers on
related aspects of land degradation identification and control
Hope to discuss the above with anyone interested, on a regular basis!
