Salt damage symptoms (S.Pini@agora.stm.it)
Date: Thu, 2 Jan 97 21:5:16 ITA

Subject: Salt damage symptoms
Dear sirs,
I'm an agronomist and I work in a public laboratory for soil analysis in
Liguria (North West Italy).
In our region major crops are flowers an vegetables often cultivate in
greenhouses and in this situation salinity problem are frequent.
Two weeks ago a grower called me to see his greenhouse for a big damage to
his roses coltivation. The leaves in the basal part of the stem
first burned and after fell to the ground. The young leaves of the upper
part of the stem were without symptoms.
The grower think that the damage was a salinity problem but our
laboratory tested the soil in October and conductivity measurement was
350 microS/cm 25 C (soil:water=1:5 weight).
The grower, in October AFTER the analysis, fertilized his roses with
liquid fertilizers with this composition:
Product A: "Hydrolized animal epithelium with amino acids at medium and
low molecolar weight:
H2O: 43%
total organic N: 7,02%
organic C: 19%
total organic matter: 44,45
Distribution dose: 24 kg/1300 square meters (about 0,3 acres)
Product B: "Bio-stimulant"
Organic Matter 32-33%
Proteins, amino acids, 12,5%
Polysaccharides 2,0 %
Humic acids 2,9 %
Distribution dose: 6 kg/1300 square meters (about 0,3 acres)
he used also Calcium nitrate kg 12/0,3 acres.
Now I need of your help to understand if the damage could be a really
problem
of salinity in the soil or other causes, like ammonia or nitrite damage.
I'm also interested to know descriptions of syntoms of salt damage, soil
testing procedure for salinity and interpretation scales.
Thank you in advance,
Stefano Pini

One needs the salt content and electrical conductivity of the extract
obtained from a saturated-amendment paste to answer the question about
possible salinity effects. Some organic amendments can contain high amounts

The symptoms that you described could very easily be
salinity or due to excessivive concentration of fertilizer
followed by a minimal application of water. The condition
could also be aggrevated by high temperatures.
Unfortunately, it is impossible to tell what may have occurred
in the past based on soil conditions in pots--which are rapidly
leached. Analysis of some of the damaged leaves would
provide the best insight.

The salt content of the applied fertilizers is a crucial component of the
assessment of this problem. If they don't contain salts and the irrigation
water is not saline (EC > 2 dS/m, than salinity is likely not a problem.
That would leave water management and some sort of "fertilzer burn" as
possibilities. At 06:50 PM 1/3/97 -0600, you wrote:

The grower, when the damage began, 3 Dec 1996 analysed his soil to
an other laboratory and the value of salinity, of saturated extract of
paste-soil was 4,6 m(milli)S/cm. In our laboratory, we do saturated
paste extract when conductivity determinated with 1:5 water:soil
method is greater of 0,8 mS/cm 25 C.
The grower said that the conductivity of irrigation water
was about 1,2 mS/cm.
The rose are not cultivate in pots but in the ground.
Thank you for your useful cooperation,

The soil salinity that the farmer measured (I.e. 4.6 mS/cm)
may well cause some salinity symptoms if water content is
low and et is high. Fertilization could add to the problem, but
the exact causative factor is still hard to determine at this
point. Leaf analysis could provide some insight into what
happened to cause the damage.

>In addition to comments of other colleagues, you should take into account
that some greenhouse "soils" are very high in organic compounds. When you
due a saturated paste of these materials, the saturation percentage is very
high and you are diluting the real salinity present in your soils, that are
not saturated in order to avoid well known anoxic problems.=20

five-eight times to estimate the real salinity. In-situ salinity sensors

mainly to a combination of these aspects: (1) insufficient leaching (you may
need large amounts of water to leach salts from materials with very high
water holding capacities), (2) high residual salts present in some of the
materials used to prepare the "soils" (especially in some turfs), (3)
localized fertilizer applications coupled to low water applications (the EC

Subject: Asparagus and Salinity
I am involved with an asparagus growing project in the Namib Desert run by
an NGO aid organisation with the aim of demonstrating the feasibility of
growing the crop on a small scale to the local people. One of my degree
students has been monitoring this for a year now, but has failed to discover
in the literature any definite values for either salinity tolerance or water
requirements.
Can anyone give me a value for either soil or irrigation water salinity that
seriously limits asparagus production?
Can anyone tell me the water requirements, or how to calculate them?
I hope these are not naive questions - this is not really my field

Thanks Dave,
I have attached an article that I recently wrote for a conference in Albany
which you might find useful. It has been published in the recent edition of
Australian Soil and Water Conservation journal.
I hope that you can read the attached file, in word for windows 6.

I am involved with an asparagus growing project in the Namib
Desert run by an NGO aid organisation with the aim of
demonstrating the feasibility of growing the crop on a small
scale to the local people. One of my degree students has
been monitoring this for a year now, but has failed to discover
in the literature any definite values for either salinity tolerance
or water requirements.
Can anyone give me a value for either soil or irrigation water
salinity that seriously limits asparagus production?
Can anyone tell me the water requirements, or how to
calculate them?
I hope these are not naive questions - this is not really my
field
Many thanks

Introduction and Questions (Pan Daiyan <daiyuanp@ere.umontreal.ca>)
Date: Tue, 14 Jan 1997 16:11:06 -0500 (EST)
From: Pan Daiyan <daiyuanp@ere.umontreal.ca>
Subject: Introduction and Questions
Hello!
My name is Daiyuan Pan. I am a Ph.D student of Universite de Montreal,
Canada. Before coming to Canada, I was working on the vegetation
ecology in the arid region of China.
One part of my thesis is about the spatial pattern of a halophilous
community in relation with soil factors (ground water table,
salinity, alkalinity etc) in the arid region of China. Now I have
two questions to ask you.
1. My study site is at the edge of an alluvial fan with little undulated
topography. The area is about 2*1km. In the raised area the ground water
table is deeper than 1.5m, whereas in the flat area the table is less
than 1.5m. The Salinity and Alkalinity also change in different
locations, but it has not obvious relation with topography. So my
question is which factors may make salinity and alkalinity has this spatial
variation? Are there some papers or books discussing the spatial
variation of salinity and alkalinity in small area? A related question is
how to draw the large scale salinity map?
2. Are there some papers or books on the indication of soil salinity by
plants?
Thanks in advance.
Daiyuan
