Did anyone respond to his question? Myself I'm interested in data about
- Assimilation, repiration rates of plants
- NPP, litter fall, litter decomposition data
- Biomass data
- and also plant development data (climate triggers for shooting, and leaf fall
for temperate and tropical plants...)
I'd appreciate any comments!

DETAILS WANTED: WATERSHED/CATCHMENT-SCALE SOIL EROSION MODELS
Introduction
GCTE (Global Change and Terrestrial Ecosystems -- a Core Project of the
International Geosphere-Biosphere Programme) is preparing to undertake an
evaluation of soil erosion models (both water and wind) as part of its Soil
Degradation Task. The Task Steering Committee consists of:
Dr Christian Valentin (Task Leader), ORSTOM, Niamey, Niger
Dr John Boardman, University of Oxford, UK
Prof. Jean Poesen, Katholieke Universiteit Leuven, Belgium
Dr Arlin Nicks, ARS-USDA, Durant, OK, USA
Dr Ed Skidmore, ARS-USDA, Manhattan, KS, USA
For the evaluation, model developers will be asked to run their models with a
series of common datasets. Further announcements will be made concerning this
exercise.
Watershed/catchment-scale models
Field-scale models for water erosion have been available for some time and are
well documented. Their watershed/catchment-scale equivalents may however be
considerably more complex (requiring, for example, integration with a GIS) and
therefore of relatively recent development. If you are a developer or user of
such a model, we would like to hear from you; please contact the address
below.

I am conducting research in forest soil situations, concerned primarily
with above ground interactions. I am a plant physiologist interested in
plant microclimate. I am currently studying the effects of whole tree
harvesting on second rotation sitka spruce. I am using TDR (time domain
reflectometry) to monitor soil moisture in the upper litter layer of
forest soils. I would be interested to hear from anyone using the
technique and would value any comments. Has anyone performed a
calibration for such organic mediums.

Apologies to other group members, but I did try to email Jess at the
address she gave in her "intro" message yesterday, but I had the
message returned with a delivery failure message.
Could you please send me a mail message, Jess, as I have some info
which may be worth your while following up and then if it yields some
interesting info of interest to the group you might consider posting
it to everyone later on.
Thanks - my email address is fraserp@lincoln.cri.nz
Cheers for now and hope you all have a nice day!!

I need some help to establish simple guidelines for crop insurance
adjustors and underwriters to follow to recognize soil crusting
hazards from textural and organic matter data.
I don't know what cut-off levels to use for silt/fine sand and
organic matter levels to define a soils potential to crust or not
crust. Would organic matter quality also be a factor?

>From experiance of 15 years of farming in Southwestern Oklahoma.
I found in sandy soils organic matter made a real difference in
crusting. An application of 7 tons per acre of feed lot manure
reduced the crusting for several years.
Crusting in sandy soils I was farming (Tipton sandy loam) if the rain
was 2 inches or less and the crop was not planted in a furrow you
clould get up most crops with a rotory hoe.
In clay soils the only way to git the crop up was to hope for another
rain but it would often make it up before the soil crusted after a
rain.
The silt soil I have farmed defy being put in catigories. I farmed
one quarter that I got a stand of cotton after 6 inches of rain. This
soil would form a crust about .25 inches thick and check into .5 inch
squares. I have never seen any soil like this it never got hard.
Other silt soils I have farmed set up much like concrete after a rain.
Good luck

Hello,
I farm near Iowa City, IA, and write for agricultural publications.
I'm interested in GPS applications, and by extension, the function of
soil type and fertility in yields.
I'm further interested in environment issues like erosion,
trafficability, leaching, etc.
Jim - Farmer - Iowa City, IA,
Howdy Jim,
Great to here that we are getting real aggies out there. It will
be nice to have a view from people with a little more experience
in reality than us pencil-pu ...... key board-pushing researchers.
( I hope I don't get too much grief for this last statement. {:-). )
I guess that this is a good time to introduce myself. I am Daniel
Fuka. I work for a private research firm in Albuquerque, NM known
as Quetzal Computational Associates. As for my background, I have
an undergraduate degree in horticulture, from NMSU, and am finishing
up a masters degree in biological systems engineering up at WSU
(the old agricultural engineering dept.) My thesis is on Corroboration
of a vadose zone nitrogen fate model SPAW by a USDA-ARS researcher
in Pullman named Keith Saxton.
Current Projects:
Water transport modeling in Landfil covers.
Distibution of crop yields for transportation prediction utilizing
remotes sensing and GIS.
Prediction of crop quality distribution, using phenological developement
modeling incorpporated into GISs.
Large scale surface energy budget solutions for PET predictions utilizing
remote sensing combined with surface fit weather parameters.
On the back burner is a project for locating high wind erosion areas
utilizing RS combined with surface weather summaries in a simple nueral
networking model.
Would love to discuss any of the above and more with
anyone interested,
Daniel Fuka

Daniel,
By phenological modeling, do you mean different varieties of a crop like
corn, or something else?
On what scale are you looking at transportation modeling for GIS
applications? From the farm, from terminals or rail heads?
I'd imagine the loess hills of western Iowa might be interesting places
to study wind erosion.
Jim - Farmer - Iowa City, IA,
Thanks for the interest. It is great to be able to talk about projects
with others in the field so that I am able to weed out mistakes that I
am making early on in the game.
Jim, in response to your questions,
For the phenological models for crop quality, I am currently trying
to estimate the percent of oils and starches in soybeans and corn. There
are several fairly well known relationships between environment and
percent protien to photosynthate in the seed. What I am trying to do
is to locate large areas with lower protien to photosynthate ratios.
I know that the greatest factor is going to be the variety of the
crop, but I am looking at taking this as a given and build from there.
For the transportation Modeling, we have been looking at the major trasport
routes. Those being, rail, highway, and barge, to and from major elevators.
I have little knowlege in this area and am taking an interest since it is
completely new to me.
Thanks for the tip on the study area for wind erosion. Currently I am
trying to get a handel on where the largest problem areas are and the
spectral absorbances of the dust generated from the wind storms.
John, In responce to your reply,
I too, am new to this area. I am trying to link up with people that have
more experience so that we can combine our expertise and make some advances.
One thing that I am interested in that will be needed in the future as the
wind erosion models develope into the quasi-3D state is environmental data
presented spatially for input into the models. Also since the erosion is
going to be worse in some areas than in others, spectral (or some other)
techniques are going to be needed to minimize the computational cost of
running the codes. Adding the 2 dimensions really tends to make the
computations costly. I am lucky since I work with several computational
physisists that have been helping me in this area.
The nueral networking model ... this is a difficult one to explain. In
a sence it is a self learning algorithem that allows the identification
of objects with certain characteristics within a group of objects. It is
utilized alot in optical character recognition as well as in scanning for
tumors ect. in human MRI produced images. This is a new field for me but
with the large number of spectral and shape characteristics that a dust
storm can have, and having tried to distiguish a dust storm from satellite
data, and failed (I think or maybe succeeded {:-)) I have come to the
conclusion that it would be nice to have a good methodology for filtering
out unwanted objects as a function of environmental conditions, spectral
signatures, and shape.
It is amazing how many people out there are interested in the Mayan and
Toltec culture. Since I have worked here many people have commented on
the name of the firm. The name was chosen due to the two partners interest
in the old aztec cultures and names for the many of our SPARCs have been
chosen to complement the interests.
Thanks for the interest,
Daniel Fuka
