From: Christopher Teh Boon Sung <chris@agri.upm.edu.my>
Subject: Texture AutoLookup
Hello everyone,
I recently wrote a computer program to determine the soil's textural class
based on the USDA classification scheme. It's a simple program that works
within Excel, Lotus 123 for Windows, and as well as a stand alone version.
I wrote this program mainly because I wanted one myself; I recently
analyzed a lot of soil samples, and I wanted a program to automatically
lookup all their textural class. You can download this program for free at
the following WWW:
http://www.agri.upm.edu.my/~chris/tal.html
I only ask you send me email before you download this program. Thanks and
best wishes in your research projects.

Subject: Soil heat flux and soil moisture
Hello all,
I know that exit a strong relation between soil thermal properties
(conductivity, diffusivity) and soil moisture content.
Now, somebody could tell me if exist the possibility to know (calculate) the
soil moisture content when I have soil temperature at different level
(surface, -10 cm, -30 cm) and I know its composition (organic matter, sand,
loam, etc.)?
Tank you in advance, and the best wish for new year.

Hello:
I am a Ph.D. student at Univ. of Illinois at Urbana-Champaign. I
am planning to couple the Hec-1 and DRINMOD in GIS environment

The mid-west of USA is tiled drained area. Due to unavailability of a
hybrid model (surface+subsurface), it has beeen very difficult to
quantify total amount of flow.
Please let me know, if such hybrid model exist or name of the

Subject: unit conversion
Hi all,
I'm not sure whether my experience is common on this topic, but I
seem to be forever coming across the problem of having to convert
measurements made in obsure engineering units into SI units or vice versa.
Can anybody recommend a text book or CD which is likely to have the
conversion factors for environmental measurements ? The sort of thing I am
thinking of here are conversions like langley/min into mW/cm^2 for solar
radiation or any of the various forms of Henry's constant. Ideally, there
would be some explanation for units, rather than just x ft lb/fortnight^2 =
y Newton; for example stokes = poise/density in cc or an explanation of the
difference between Makkink evapotranspiration and pan evaporation would be
good. The most useful conversions would be between experimental units and
SI units.
yours, in hope

Indian Council of Agricultural Research
and
International Fertilizer Development Center
ICAR-IFDC International Training Program on Computer Simulation for
Crop Growth, Soil Water-Nutrient Dynamics, and Fertilizer Management
February 17-28, 1997
Rationale
Today more than ever, increased food production depends on the
judicious use of resources. Many soil, climatic, plant, and
management factors affect a crop's response to irrigation,
fertilizer, and other management practices. Determining appropriate
crop management strategies under these uncertainties has significant
agronomic, economic, and environmental implications. Computer
simulation models of the soil/crop/atmosphere system can make a
valuable contribution to both furthering our understanding of the
processes determining crop responses and predicting crop performance
in different areas. With the increasing availability of small
personal computers, user-oriented simulation models will greatly
facilitate the task of optimizing crop and nutrient management.
They can also be used to investigate environmental and
sustainability issues of agrosystems.
The International Fertilizer Development Center (IFDC), in
collaboration with the U.S. Department of Agriculture (USDA),
Michigan State University, University of Florida, University of
Georgia, International Consortium for Agricultural Systems
Applications (ICASA), and many other research organizations,
has been at the forefront in developing crop models and decision
support systems suitable for use and application in developing-
country agriculture. The Indian Council of Agricultural Research
(ICAR) and IFDC are organizing this International Training
Program on Computer Simulation for Crop Growth, Soil Water-
Nutrient Dynamics, and Fertilizer Management to be conducted in
Modipuram near New Delhi, India, during February 17-28, 1997.
Program Content
The program will describe the practical approaches to simulating
the effects of soil, climatic, cropping, and management factors
and their interaction with nutrient needs in crops. The program
will also show how the processes of soil nutrient transformations,
crop growth and uptake of nutrients, and response to fertilizer,
irrigation, and other management practices can be simulated. The
training program will make extensive use of the CERES (rice,
wheat, sorghum, and maize) and GRO (peanut and soybean) models for
crop growth, development, and response to water and nutrients.
Procedures for managing soil, crop, and weather data will be
described. Computer programs to create, run, and analyze both
single crop and crop-rotation sequence will be described. More than
50% of the program will be devoted to practical sessions on personal
computers. The participants are encouraged to bring their data (soil,
crop, and weather) for model validation and application purposes.
The models used in the program are integrated into the DSSAT software
package by the International Consortium for Agricultural Systems
Applications (ICASA).
Program Objectives
The objectives of the program are to increase the participants'
knowledge in the following:
1. Soil water, soil and plant nutrient dynamics, and crop growth
in cereals and legumes.
2. Application of CERES and GRO simulation models to cropping,
nutrient and water, environmental and sustainability issues.
3. Data requirements, collection, and acquisition for systems
simulation.
4. Application of integrated decision support system (crop models,
data base management and geographic information system) in
precision agriculture.
Requirements
1. Participants should be university graduates currently engaged
in crop production-related research or planning.
2. They should have some understanding of soil science and
agronomy and be relatively familiar with the terminology used
in these fields. An in-depth knowledge is, however, not a
prerequisite.
3. They should have had some exposure to personal computers.
4. They should be fluent in English.
When and Where
The program will begin February 17, 1997, and end February 28, 1997.
The program will be held at the Project Directorate of Cropping
Systems Research at Modipuram, Meerut, in Uttar Pradesh. Modipuram
is 70 km from New Delhi. ICAR will provide transportation to and from
Indira Gandhi International Airport, New Delhi for participants.
How to Apply
The program fee of US $1,500 is due with the application for
enrollment. To apply for enrollment in this program, complete the
attached form and mail it to IFDC by February 7, 1997. If an
organization wishes to enroll more than one participant, it must
supply information on each applicant.
The program fee covers the registration for the 2-week program,
transportation for field trips, resource material, and tea/coffee
breaks. It does not cover food and lodging or medical and incidental
expenses during the program or air transportation between New Delhi,
India, and the participant's home country; each participant is
responsible for these costs. The board and lodging of participants

Subject: CERES-Maize and CN runoff method
I am looking for suggestions on a way to adjust my rainfall or CN in the
model to more closely represent actual runoff from a site in Florence, SC.
My problem is that storms have a short duration high intensity during part
of the year. The storm type is ignored by the model and needs to be
adjusted in some other way. I would prefer to alter the weather input
because during times of year when the storms are of a more typical type, the
new CN would be incorrect.
Any comments or suggestions on my problem would be greatly appreciated.

You probably need to look at a subroutine using hourly rainfall data.
If ceres-maize is still using daily data (you didn't say what model
version) then it assumes that rain fell over 24 hours. A 15 cm
storm occurring in 2 hours will cause different runoff patterns than
one lasting 20 hours.

Subject: MORE INFO ON CERES-Maize and CN runoff method
As far as I know, the model only accept daily rainfall data. Therefore, I
believe I must adjust this data before entering it into the model. My
rainfall is from recorded history. I have actual yields to verify the
model, but the water balance allows too much infiltration and the plants are
not showing water stress as much as they should. The results on most of my
soils indicate a much higher than actual yield.
Thanks for responses so far.

Subject: Re: MORE INFO ON CERES-Maize and CN runoff method
Hello, Group.
My name is Pete Spyke, and I have been a lurker for awhile. This
current discussion led me to comment. I have been working with
a company called Adcon Telemetry, which manufactures automated
weather stations. The stations have sensors, including rainfall, which
measure surface information and relay it to a base station via radio.
The Base is connected to a PC, which will accept the data and
load it directly into models. They have had great success in a number
of ag industries around the world.
You can read more about them by following their link on our company
Web Page: http://members.aol.com/aracitrus
I'm a citrus grower in Florida, and am working on development of
Precision Ag for our industry. Adcon has emerged as the best choice
for loading weather-sensitive models.
Hope this helps.
