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. ---------------------------------------------------------------------------- ------- Francesca Di Pietro Joint Research Centre Institute for Systems, Informatics and Safety Systems Modelling and Assessment Unit, tp 650 21020 ISPRA (VA) ITALY Phone: (39) 332.78.90.61 (direct) or (39) 332.78.52.46 (secretary) Fax: (39) 332.78.93.94 EMail: francesca.di-pietro@jrc.it

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.

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! Scott Taylor NSW Department of Land and Water Conservation P.O. Box 371 Grafton NSW, 2460 Australia Int. ph. 61 66 42 7799 Int. fax 61 66 43 1161 Scott Taylor staylor@nor.com.au (home) or staylor@dlwc.nsw.gov.au (work) ...Be a beaver - work hard, make something, share, keep getting up when life knocks you down, look after what's yours, have respect for what's bigger than you are and play nicely with the other animals!
