Jennifer,
This reply is not entirely about what you asked, but in your searches
(electronic, library, etc.) also look for karst topography. Karst
topography includes sinkholes. You may already know about this term, but
wanted to make sure. Hope this helps.

Hi Marylene,
Structural porosity is that which occurs between structures in the soil
(peds), commonly described as blocks, nuts, etc. This type of porosity
includes voids between the faces of the peds, as well as polyhedral
shaped voids where peds abut.
Textural porosity is formed between the primary soil particles which may
be any size ( the pore size between stones will be much greater than
that between silt-sized particles).
Don't forget biological porosity which includes root and worm channels.
As a general rule:
Structural porosity == inter-ped porosity
Textural porosity == intra-ped porosity
I hope I have correctly interpreted your question

Hi
I am wondering if someone could help in giving advice on
any special package for interpolating data from a graph or advice on
interpolation using packages such as Excel if possible.
I have the soil moisture characteristics curve and data of
soil moisture content for different dates. I wish to predict soil
tension from a large amount of data without using a moisture content-
tension function and soley from graph, the same as
matching moistures on a smoothed curve of soil moisture
characteristic curve for pressure heads directly from the graph.
e.g.
I have:
x y
1 3
2 4
3 y1
4 y2
5 7
and I want to extrapolate y1 and y2 using the equation of the
smoothed curve not the statistical function.
Any advice would be appreciated.
Thank You

Hello fellow subscribers!
I'm a PhD student in the Department of Soil Science, the University of
Adelaide, South Australia. My project has been looking at the influence
of inorganic matrices on the decomposition of different organic
materials.I am about to commence writing my thesis in earnest, having set
myself the deadline of December for a complete first draft.One of the
last major experiments I did was to perform FAME analyses on different
samples taken from different time periods during an
incubation/decomposition experiment involving straw.I now have literally
tonnes of numbers to wade through and am wondering if anyone knows of a
database where one can put in a fatty acid structure (eg. 10:0 3OH) and
find out if this fatty acid comes from bacteria, fungi, protozoa, etc?
I've had a good look in the literature and have identified about 20 peaks
but still have 80+ unknowns.
Thanks for your help.

Cindy,
1. Chlorophyll meters:
Several research groups have been working on this topic in the U.S. as well
as groups in
Europe, Australia, etc. For examples, see:
Follett et al. 1992. Use of a chlorophyll meter to evaluate the N status of
dryland winter wheat.
Commun. Soil Sci. Plant Anal. 23:687-697.
Fox et al. 1994. Using a chlorophyll meter to predict N fertilizer needs of
winter wheat.
Commun Soil Sci. Plant Anal. 25:171-181.
Dwyer et al. 1995. Quantifying the nonlinearity in chlorophyll meter
response to corn leaf N
concentration. Canadian J. Plant Sci. 75:179-182.
Several other references are available too (Reeves et al.) and research has
also been initiated on
many crops other than wheat (e.g. rice, cotton, maize). But these few should
get you started.
We have been looking at genotypic differences within commercial varieties of
wheat and have
observed some confounding differences. It's not as simple as many people
once thought.
2. Plant nitrate meters:
We have been unsuccessful in developing a good test using plant nitrate
concentrations for
wheat. Many factors are involved in determining the leaf nitrate
concentration at any given
time, including:
++ transpiration factors (soil moisture, temperature, environmental
conditions, etc.)
++ soil nitrate concentration
++ rate of nitrate utilization within the plant (including nitrate
reduction and utilization) which
is strongly influenced by temperature, light intensity, etc.
We have measured high nitrate concentrations during a cloudy period of the
day and then low
nitrate concentrations during later sunny period of the same day. It makes
it quite difficult to
develop one "critical value" that can be used for fertilizer predictions.
The use of nitrate concentrations for diagnostic purposes is used with
moderate success for crops
such as cotton. However with cotton, only the petioles are analyzed (the
conductive portion of
the plant) and the leaf blade itself is not used. Perhaps the test might
work better with grain
crops if only the nitrate present in the midrib was analyzed (by first
removing the leaf blade
before putting the sample in a press).
A little investigative work in the library will provide more information on
some of the topics
covered here.
Good Luck!

Hello Robert
Thank you for the references and the comments. We're hoping to play
around with this a little with some studies on foliar N that we are
planning across Western Canada. Your input on the variablity of the
nitrate level in the leaf is welcome. It's good to hear direct feed back
from someone with some experience in the area before we go blindly in
to a study. Sometimes the information in a paper has been somewhat
"sanitized" in terms of the frustrating practical problems with techniques
before the paper finally hits publication.
Thanks

"Accounting the watershed benefits" of a Tree Growers' Cooperative (TGC)
plantation in India. In a 20 hectares(small watershed) of land of TGC I have
estimated the soil loss on a wasteland covered by sandy loam,red lateritic soil
using universal soil loss equation (USLE).
I have found two different soil loss values : one before TGC plantation
and one after TGC plantation.
My output looks something like this :
soil loss rate :
'X' tonnes/hect./year before plantation and 'Y' tonnes/hect./year
after TGC plantation.
Now my question is : How should I convert these soil loss for each tonne to
its monetary value (in $ or in any currency value) ?
If you have, at any time, come accross the similar problem, could you pl.
tell me how much value you have considered for each tonne of soil loss ?
If any reference is available pl. advise me.
Thank you for giving me your invaluable time.
Please reply me in my e-mail address.

Take the incremental sediment values and try one or both of the two most
common methods, which are:
1) Wander downstream and look for negative impacts from sedimentation. Put
a value on it. This, however, is often a less-than-straightforward
exercise. You need to think about the efficiency of sediment transport from
you site to theirs and discount the dollar value back. Unless you are lucky
enough to have a small watershed, high transport efficiency, and something
straightforward like small irrigation canals that are silting up and
requiring periodic cleaning out (whose costs you can estimate), the effort
to derive an offsite cost might be too lengthy and based on highly
questionable assumptions. If you are "lucky" and have a straightforward
cost that you can estimate, do not forget to look at what is done with the
sediments as they might provide a benefit which must be subtracted from your
costs.
2) Estimate on-site costs. National accounts generally look at the market
value (border price) of the nutrients lost. You could probably use the
financial cost unless your perspective is national or international (versus,
e.g., from the landowners perspective). If you know a bit more you could
relate nutrient loss to site productivity for the particular species of
interest...a bit trickier, but do-able. You do not have to have
species-specific data, just some defendable proxy.
Keep it simple with conservative parameter estimates and then it might be
justifiable.

Hello all subscribers,
Could I lend some time from you all answering my small question ?
I am working on an UNDP project where the research is focused on
"Accounting the watershed benefits" of a Tree Growers' Cooperative (TGC)
plantation in India. In a 20 hectares(small watershed) of land of TGC I have
estimated the soil loss on a wasteland covered by sandy loam,red lateritic
soil
using universal soil loss equation (USLE).
I have found two different soil loss values : one before TGC plantation
and one after TGC plantation.
My output looks something like this :
soil loss rate :
'X' tonnes/hect./year before plantation and 'Y' tonnes/hect./year
after TGC plantation.
Now my question is : How should I convert these soil loss for each tonne to
its monetary value (in $ or in any currency value) ?
If you have, at any time, come accross the similar problem, could you pl.
tell me how much value you have considered for each tonne of soil loss ?
If any reference is available pl. advise me.
Thank you for giving me your invaluable time.

The most straightforward way to put a monetary value on the soil is to
consider its replacement cost on your local market. I know nothing of your
local landscaping practices, but here in Syracuse, NY, there are companies
that sell soil for use in new housing developments or on public works
projects. It would be most realistic to get the delivered cost for a full
truckload rather than for a price for one ton, which would be more expensive.
I think that this method is simpler than determining the nutritive value of
the soil lost, because you are planning to plant trees that will have a
future value. The future value of the trees will contain the nutritive value
of the soil and will reflect that value better than a generic nutritive value
would.
The environmental costs of unwanted sediments depend on what is downstream.
Determine what the negative effects might be and then research what it costs
per ton of soil to remediate those effects. You will want to weight the costs
to reflect the way the actual sedimentation. For example, 70% of the
sediments may settle in an area that costs X amount to remediate, 30% may
fall in an area that costs Y to remediate: (70X + 30Y) / 100 = remediat cost
per ton. Of course, there is the problem that some remediation is impossible
or the cost is unknown, but it is important not to ignore the cost -- you may
have to guess. Also, much of the sediment will be unaccounted for.
The soil replacement costs plus the environmental remediation costs give the
value per ton of reducing soil erosion.
I assume that for a more complete accounting, you plan to include other
benefits, such as the future value of the tree harvest. Also, the project
probably has a time frame. Let's say that it's 50 years. You should estimate
the value of the ALL the soil for EACH year (assuming that soil loss will
change as the trees grow). Estimate a projected value for the years that you
plan to harvest trees (or their recreational value if they will not be
harvested). Add each year's values together and divide by 50. That will give
you the average annual value of the project. This may be a beeter way of
looking at the project than just looking at the per-ton value of the soil,
especially if you need to convince politicians or businessmen to fund your
project.
Please forgive me if I am repeating things that you have already considered.
Good luck on your project.

Hi,
does anyone know whether there is a very recent edition of
"Standard Methods for the Examination of Water and Wastewater, 18th Ed"
(Greenberg et al, eds, APHA/AWWA/WPCF, 1992)
ie. more recently revised than the 18th ed. or later than 1992.
Thanks in advance,
Andrew.

>Hi:
The 19th edition, was published in 1995. It can be ordered from Water
Environment Federation in the United State. Their phone number is
703-684-2452 and their fax number is 703-684-2492.
I believe that they have a distribution center in Australiain New South
Wales. They distribute through The Australian Watewr and Wastewater
Association. Their Phone # is (02) 413-1288 and the fax # is +612 413 1047
Good Luck.

Participatory Development of a WWW Database
Agriculture (S)
In an effort to incorporate the most relevant agriculturally-
related Web Reference resources within the CyberStacks(sm)
collection, we have established this site to obtain user
preferences for those categories that are of greatest collective
interest.
We invite users to select from categories and subcategories of
topics found within the hypertext outline of the Library of
Congress classification schedule for Agriculture (S) below.
Agriculture (General) S
Plant Culture SB
Forestry SD
Animal Culture SF
Aquaculture, Fisheries, & Angling SH
Hunting SK
Users are requested to simulate the selection of topics that
could meet an information need in some field of Agriculture.
While NO resources are incorporated within these categories and
subcategories at this time, the aggregate selection of topics by
all users during the month of September will greatly assist in
identifying the subject categories that users most desire.
This aggregate selection of categories and subcategories will be
monitored from log reports. At the beginning of October, the
cumulative activity will be compiled and used as a guideline for
selecting specific resources from the CyberStacks(sm) Title Index
for priority incorporation within the CyberStacks(sm) collection.
Participants are encourage to select resources at those times
that they seek a specific information Reference resource in the
field of Agriculture, acting as though they were involved with a
real search of the CyberStacks(sm) collection.
User participation in the further development of CyberStacks(sm)
is greatly appreciated!
