The conference is jointly organized by the Institute of Advanced Studies (UNU/IAS) of the United Nations University (Tokyo) and the UNESCO Microbial Resources Center (MIRCEN-Stockholm) under the UNU/IAS prgramme on "eco-restructuring for sustainable development" which advocates the zero emissions concept of wastes and by-products utilization for income-generating activities and those that contribute to a cleaner environment. The purpose of the conference is to permit Internet access to a comprehensive documentation of past and current work on integrated bio-systems, to enable authors to share knowledge and know-how and to encourage participants to interact with the authors. The Internet confer ence will gather biologists, scientists, engineers, sociologists, economists and project coordinators and members of the electronic Network on Integrated Bio-systems. Scope The conference will deal with a variety of topics on the science, technology and practice of integrated bio-systems in agriculture, aquaculture and industry for energy and primary food production, waste treatment & utilization, food processing. Papers are invited on integrated bio-systems for localized site applications, such as fish-bivalve polyculture systems in aquaculture; crop-mushroom-compost systems in agriculture; integrated agriculture-aquaculture systems (e.g. rice-fish systems); systems for wastewater treatment and utilization, water quality management (e.g. sewage wastewater-fish-hydroponics-wetland systems) and solid waste treatment and utilisation (e.g. municipal solid waste-vermiculture-compost-duck systems, and livestock manure-biogas-crop/horticulture systems). Scientific papers related to the above topics on their microbial ecosystems, their materials balance and nutrients flows, transfer of toxics in the food chains, economic analysis and assessment of whole systems, ecological bioremediation, etc. are also welcomed. Other systems may have a wider landscape applications, including coastal zone aquaculture and resource management, agro-forestry, lowland-upland, urban-agriculture, lakes, villages, communities, industrial and recreation parks, cities) and those at a regional level that cover socio-economic and political issues.

Date: Thu, 25 Sep 1997 08:40:09 -0500 From: "Robert M. Caldwell" (serc018@UNLVM.UNL.EDU) Subject: The history of ag modeling. Where we are headed in the future... Dear AgModels-L list members, I would like to kick-off two lines of discussion. Thread 1: A time-line for key developments in modeling For the sake of newcomers to ag modeling, I think it would be good to review our history. Please submit to AgModels-L your personal opinions on the most important events that have affected our progress. Key citations would be nice, though I would also like to hear about accomplishments that never made it into a publication. Quantification of changes (e.g., growth in lines of code, number of variables, power of computers) would be nice to go along with the description of key events. To get things started, two items of interest to me would be: -- When were the earliest crop simulation models developed? Specifically, when was a model for leaf area growth first coupled with a photosynthesis model? -- When were the earliest "validations" of a crop simulation model done? Who first put together an observed-versus-predicted comparison? Thread 2: A projected time-line for what our future holds Setting a research agenda in modeling is, or should be, closely tied to the social needs and technological opportunities that will exist in the future. Please pass along to AgModels-L citations for literature (including the popular press) that make those kind of projections. For this thread, I suggest we limit ourselves primarily to citations and not debate personal hunches (though I would like to hear from anyone that has made a major programmatic shift because of what they project will happen in the future). Quantitative predictions are the best. If we survive, we should be able to test them, right? I would like to see references that try to answer: -- What are the best estimates for the growth in computer power over the coming decades? -- What changes are we likely to see in agriculture's use of computers? What types of user interfaces will we use? How will farmers use computers? For these two threads, please make your submissions brief and focussed. As a courtesy, you might start your subject line with "History:" or "Future:" so that readers can quickly judge the contents.

Date: Fri, 26 Sep 1997 12:24:26 +0000 From: drake@EROLS.COM Subject: Grow Chamber Model I am working on a grow chamber for carnivorous plants. The goal is to provide optimum light intensity and spectrum, enough CO2 whether by ventilation or a yeast-sugar-water mixture to make CO2 or any other means, a high humidity, and a warm but consistent temperature around 80 degrees fahrenheit (+- a few degrees). I have not decided on a particular light source yet, though I am seriously considering Metal Halide lights or High Pressure Sodium with the optional Agricultural spectrum feature (slightly more expensive). The walls of the grow chamber will most likely be made of glass, and lined on the inside with mylar to reflect light back towards the plants. Depending on the shape of the grow chamber, one or all of the walls will be removable or slide up to allow access to the plants. Now to the conflict when constructing this model: The goal of greatly accelerated plant growth is hindered by limiting factors. The greatest of these limiting factors is light. My question is about the geometric shape of the grow chamber. Which geometric shape would provide *maximum* reflection of the light by the mylar? I suppose this would involve angles of reflection, etc. For instance, a hexagonal shape in 3 dimensions would reflect light off of 8 surfaces at certain angles, while an octagon in 3 dimensions would reflect light off of 10 surfaces at even more angles. The question becomes more complex with a spherical shape (with angled panels to comprise the overall spherical shape) where light would be reflected not only off the sides, top, and bottom, but from the diagonal panels that connect the sides to the top and bottom. Again, my question is: Which geometric shape provides maximum light reflection in the grow chamber in this scenario? Any help would be GREATLY appreciated. :)

Therefore, consider building using concave shaped mylars shields/mirrors. You can use an equation relating the angle subtended by an arc at the center of the sphere to decide how to construct the mirrors: the larger the angle the more the image will be formed closer to the vertex. You can also use a "stop" to control spherical aberration. Without the refractive indices etc. it is hard to say more... Ranjan

It seems that having a hexagon (or other geometry..) will cause a great deal of sidelighting to fall on you plants. This would complicate the inputs of any light interception model you try to use to simulate conditions on your chamber (but maybe youre not going to do this?). As far as using mylar, you should be aware that it will degrade with time and become brittle. We use sheets of Coilzac, a thin, highly reflective metal sheet that is put inside EGC growth chambers. We built a box around our plants that gives us a known, fixed area and this helps us express light interception on an area basis. As far as the co2 enrichment system goes, you may consider having a blower with a rotameter and a tank of pure co2 (depending on your air flow). This could be upgraded to a mass flow controller and a PID based control system. You may have to blow the co2 through potassium permanganate (Air Repair) to remove ethylene contaminants from the tank gas. The only major difference between the MH and HPS is that MH lamps provide blue light and HPS doesn't, which may affect stem elongation etc. Otherwise both provide sufficient PPF, we get close to 2000 umol m-2 s-1 over an area of 1 m2 with only 4 HPS lamps. We also use a recirculating water bath under the lamps to remove a great of heat (nonphotosynthetic longwave radiation) which helps the leaf temperatures to remain well below air temp (1-2 degrees). I hope this helps. OM OM oscar@mendel.usu.edu http//www.usu.edu/~cpl/index.html

The manager of the mail group suggested me briefly review the history of the simulation models. From my point of view, ELCROS, created by Centre for Agrobiological Research (CABO), the Netherlands in the early 70's is the first crop simulation model presented in computer in the world. I am sure many models popular today are based on the ideals.

Date: Mon, 29 Sep 1997 14:51:42 -0500 From: "E. John Sadler" (sadler@SUNBRN.FLORENCE.ARS.USDA.GOV) Subject: Re: The history of ag modeling. Greetings, For what it's worth... In a review of crop simulation models for my dissertation (1983), I considered the first comprehensive work to be that of Monsi and Saeki (1953) Uber der Lichtfaktor in den Pflanzengesellschaften und siene Bedeutung fur die Stoffproduktion. Jap. J. Bot. 14:22-52. (the English version by Kanasagi and Monsi in 1954 is easier to read! Jap. J. Bot. 14:304-324) This emphasized the importance of light in dry matter production and was the first I found to divide the canopy into layers. Monteith (1965), De Wit (1965) and Duncan et al (1967) all modeled photosynthesis based on radiation interception. Stewart and Lemon (1969) in an interim report described simulation of net photosynthesis using Duncan's light interception model. Lemon, Stewart, and Shawcroft (1971) followed up with "The sun's work in a cornfield" in Science. Several papers from 1968 to 1978 followed up on Duncan's work, including those by Loomis, Williams, and Duncan himself. The state of the art at the time (1970) was described in the IBP/PP technical meeting "Predeiction and measurement of photosynthetic productivity" in Trebon, Czechoslovakia, in September 1970. ELCROS was described there by De Wit et al. Several papers there reviewed models (Ross, Anderson, and Kuroiwa, separately), which might be a good place to go for historical review. Others, including B. Acock (Basil, that was you, right?), JHM Thornley, Monsi, OT Denmead, Uchijima, Tooming, and McCree presented papers on processes within models. Anyone interested in citations contact me directly. If I still have this in ASCII form (word processors were somewhat more primitive back then!), I can e-mail some of them to you, but I don't want to fill everyone's in boxes with them.

If you mean by "simulate conditions" that I want to simulate natural conditions, the answer is no. I am interested in scientifically growing plants, deleting (or highly minimizing) all limiting factors to enhance growth to greatly accelerated rates. I suggested a hexagonal shape as a possibility because of the "Phototron" by Pyraponic Industries, which chose the shape I assumed due to something in the geometry that makes it more effective than another shape; perhaps this was just done for appearance then? Where can I purchase "Coilzac"? If not from a local store, than where mailorder (preferably with a web-page)? By the way, what is an "EGC" growth chamber?
