Senior design team travels to Mexico City A professor and two students of Biosystems and Agricultural Engineering traveled to Mexico City, Mexico trying to establish international contacts and learn more about Mexican agriculture. Joe Vadder and Sherry Britton, Biosystems Engineering undergraduates, are two of the members of the biosystems engineering senior design team who made the educational trip. They were accompanied by Dr. Richard Whitney, one of the Biosystems and Agricultural Engineering professors instructing the class. The three individuals traveled to Mexico City to research Mexican farming techniques and bring back information to help the team in the design class. The team is developing a grain planter to be used behind a two-wheel Chinese tractor, Vadder said. “The purpose of the device is to plant wheat on raised beds which can be irrigated and managed so that it can get higher yields than on flat surfaces,” Whitney said. The team hopes that this concept will be implemented in different countries, Britton said. While Whitney, Vadder and Britton were in Mexico, they stayed at the
International Center of the Improvements of Wheat and Maize, CIMMYT, headquarters. CIMMYT is an internationally funded, nonprofit research and training center focused on providing a range of products and services designed to improve the profitability, productivity and sustainability of maize and wheat systems in poor countries. “CIMMYT is trying to get third world countries to grow more wheat,” Whitney said. Whitney, Vadder and Britton studied Mexico’s agricultural cultures by looking at several different planters and farms. They also visited the University of Chapingo. “I enjoyed seeing the different types of agriculture,” Vadder said. Britton said this was the first time she had traveled internationally, and she did not know what to expect. “It gave me a whole new perspective on Mexico versus the U.S.,” Britton said. “You get a different perspective when you actually talk to the people.” While in Mexico City, Britton was interviewed by a Mexican high school student. The student’s English assigncontinued on page 6

Students to compete in tractor pull Oklahoma State University Biosystems Engineering students will show off their hard work and dedication as they compete in the second annual Quarter-Scale Tractor Pull Competition in Moline, Ill. May 20 to 24. This year OSU will enter a senior team and a junior team in the competition. The senior team will build a tractor from scratch while the junior team will make modifications to last year’s quarter-scale tractor. The senior team consists of Bron Howard, Brett Whaley, Stewart Reed, Joe Vadder, Dustin Simmons, Carly Washmon, Duane Needham and Travis Tsunemori. Jake Holloway, Chad Fisher, Jason Walker and Adam Bohl make up the junior team. Bron Howard, Biosystems Engineering senior, said the team will hopefully do better than they did at last year’s competition. “We are more prepared for what we have to do, and we are getting more feedback from Biosystems and Agricultural Engineering professors. Both teams will compete against 34 other teams from universities across the United States in several different categories. These categories include presentation, design report, tractor pull, overall competition, safety, newest design, unique idea, best looking and best instrumentation. Winners of different categories receive trophies, money, equipment worth $3000 or just bragging rights, Howard said. Howard said both teams have raised money to pay for the building and modifications of the tractors. “We have received money from the Activities Fee Allocation Process and from donations,” Howard said. “Stillwater Equipment has been really good to us.” The students work on the tractors on weekends and in their spare time during the week, Howard said. “We divide the responsibilities just like it is in the real world,” Howard said.
The teams will participate in Tulsa’s Starbirds Car Show as a trial run before the major competition in May. The Tractor Pull is part of the National ASAE Design Competition for students to gain practical experience in the design of drive train systems, tractor performance, engine design, manufacturing, manufacturing processes, analysis of tractive forces and weight transfer. Working on the tractors is a learning process for the students, Howard said. “What we do not cover in class, we learn on our own by building the tractors,” Howard said.

OSU-developed smart machine decides when to spray plants “The plant tells us what it needsright now-as we go through the field,” said John B. Solie, OSU biosystems and agricultural engineer and project spokesperson for a team of OAES researchers designing, developing, and testing firstof-its-kind, sensor based application equipment. Solie is referring to a commercial tractor sprayer equipped with computers and sensors developed by the researchers. As it goes through a field, sensors “read” the plant material and transmit the data to computers on the machine. These computers, in turn, tell the spray equipment how much to apply. The liquid sprayed can be either herbicide or fertilizer, depending on what is programmed and loaded for the job. To a novice, the prototype sprayer appears strangely uncomplicated. Basically, it’s a commercial self-propelled sprayer with a laptop computer mounted at the driver’s right plus special nozzles and small white boxes housing sensors and tiny computers. The machine is also easy to operate. However, looks do not tell the complete story. The development of this still unnamed smart machine was no easy endeavor. Solie said the computer, sensing devices, and wiring are largely the brainchild of Marvin Stone, OSU biosystems and agricultural engineer. The sensors are based on light radiating from
by Jacqueline Dahlgren plants and other biomass in the visible and the near-infrared spectrum. The sensors generate numbers based on light intensity; those numbers are fed to the computers that control spray application through the nozzles. Stone also has a research reputation for developing computer apparatuses “for making one part of a machine talk to another part” that served as head of the U.S. delegation, writing international standards for communications on agricultural equipment. While Solie credits Stone, he said some 30 people, including students, have made important contributions to the new
variable rate sprayer, which has not yet been produced commercially. He describes its development this way: “In 1991, Tom Peeper, OSU agronomist said he’d like to have a sprayer that could see bindweed in fields and only spray in needed areas, rather than the entire field...that we could save a large amount of herbicide.” “Marvin Stone had already designed a sensor, which now has had several generations of improvements, that could detect bindweed in fallow conditions.” “I was also thinking at the time that it would be great if a sensor could detect the nitrogen needs in a wheat plot. We talked to Bill Raun and Gordon Johnson, both OSU agronomists, who know a lot continued on page 8
John Solie demonstrates the smart tractor. It contains sensors that read the plant material and tell the spray equipment how much liquid to apply.

Design Team, from page 3 ment was to ask questions to an English person. Britton was tape recorded while answering these questions. She also got her picture taken by the student. The team is currently in the process of building the grain planter, Vadder said. “We have the design nailed down, but we don’t have any drawings yet,” he said. The team hopes to have the device completed by April. The final product will then be shipped to Mexico, and the whole class will travel to Mexico City in May to demonstrate the solution to representatives of CIMMYT and students and faculty of the University of Chapingo. The individuals were able to sitesee while in Mexico. They visited the pyramids, the Anthropology Museum and the downtown of Mexico City. They also had the opportunity to visit with a Noble Prize winner, Dr. Norman Borloug. All three are excited to travel back to Mexico City in May.

BIOEN prof Whitney announces retirement Dr. Richard W. Whitney will retire July 1, 1999 from the Oklahoma State University Biosystems and Agricultural Engineering Department after working for 31 years. Whitney is going to take advantage of opportunities outside of OSU. “After working for 31 years, you begin to think that maybe you ought to do other things,” Whitney said. Whitney, a native from Osawatomie, Kan., graduated with his B.S. degree in Agricultural Engineering at Kansas State University in 1961. He also received his M.S. and Ph.D. degree in Agricultural Engineering from OSU in 1967 and 1972. His fields of study included farm power and machinery, farm structures, rural electrification and processing of farm products. Whitney began employment as a temporary instructor for Kansas State University in 1961. Whitney moved to OSU in 1962 and became a BIOEN instructor and then worked as a graduate research assistant from 1969 to 1972. In 1972, Whitney became an assistant professor at Louisiana State University, but came back to OSU in 1975. Whitney was promoted to associate professor in 1979 and then to professor in 1984. Throughout the years, Whitney’s major areas of interest in research and teaching have been based on application technology, mechanization equipment development, agricultural machinery and design and agricultural power and power units. After retiring, Whitney plans to work on his consulting

company and write a couple of books. “I want to write on the aerial application industry and either on mailbox design or ranch entry ways,” Whitney said. Whitney is a member of the American Society of Agricultural Engineers as well as the Society of Automotive Engineers. He has also received some awards and honors such as the NDEA Fellowship, Seven Wonders of Engineering in Oklahoma Award, Outstanding Engineering Achievement Award and USDA Unit Superior Service Award.
Charles, from page 1 most complete line of traditional trenching products, but it also is continuing to set the standard for horizontal directional boring products and other trenchless technology techniques. “Ditch Witch and Subsite Electronics products are used all over the world to install power and communications cable, water and natural gas lines, sprinkler and irrigation systems and other types of buried service lines,” Branson said. The Charles Machine Works, Inc. controls the research, design and manufacturing of every piece of equipment in the Ditch Witch and Subsite Electronics product line. The plant includes the main offices, a manufacturing area, a product development center, the Ditch Witch Training Center, the Subsite Electronics design and manufacturing facility and a directional boring drill pipe manufacturing facility. The Charles Machine Works, Inc. was founded by Ed Malzahn who invented the first compact trenching machine in 1949 which launched an entire industry. “Since that time, the company has built and sold more than half of the world’s service-line trenchers, pioneered the development of vibratory plowing equipment and is recognized as the leader in the directional boring industry,” Branson said. The company is named for the late Charles Malzahn, father of company president, Ed Malzahn. The Charles Machine Works, Inc. takes pride in training their employees. “Training is a major concern and an integral part of the Ditch Witch customer service effort at The Charles Machine Works, Inc.,” Branson said. “By increasing an employee’s level of confidence, the company strongly believes that training improves on-the-job productivity.” The company’s worldwide dealer organization has caused much of the success to the Ditch Witch and Subsite Electronics brands. Independently-owned Ditch Witch dealerships are dedicated to Ditch Witch and Subsite Electronics products and services, Branson said. These dealers stand by the philosophy: “We are the underground authority, worldwide.”
Noyes shares grain storage technology with Chinese Ronald Noyes, Extension Agricultural Engineer, traveled to China to learn more about the storage of grain around the world. Noyes attended the Seventh International Working Conference for Stored Product Protection in Beijing Oct. 14 to Oct. 19. “The purpose of the conference is to provide scientific information of the research of grain storage in all countries that want to participate to improve grain storage,” Noyes said. Noyes presented two oral technical papers and two posters at the conference. He discussed the guidelines for Ronald Noyes sealing steel grain bins for fumigation and the advances in recirculation fumigation technology in the U.S. Approximately 600 people from over 30 countries attended the conference, Noyes said. This was Noyes’s second time to participate in the conference. He traveled to Camberra, Australia to attend the conference in 1994. Noyes also participated in the Controlled Atmosphere and Fumigation Conference in Cyprus in 1996, which he organized a technical session focused on grain and was appointed to the board for the conference in 2000. Noyes is one of two U.S. scientists on the board. During the conference in China, Noyes attended technical sessions and toured the Beijing Grain Bureau, the top grain storage facility. “We saw the old method of storing grain in China,” Noyes said. “The grain was stored in bags and covered with woven mats made out of grass.” The Beijing Grain Bureau has progressed to modern structures, Noyes said, and they are now building a concrete silo complex. Noyes is currently helping with the design of the soon-to-be Stored Product Research and Education Center at Oklahoma State University Noyes attended the Seventh International Working Conference for Stored Product Protection to gain information for the construction of the center. OSU’s Stored Product Research and Education Center will provide programs of excellence in research, education and training related to the management of stored grains, grain products and other bulk commodities, benefiting Oklahoma, the nation and the world.

Students learn teamwork skills while participating in class projects Biosystems and Agricultural Engineering students focused on teamwork skills while taking an engineering software class last fall. Ronald Elliott, class professor, said it is the first course that BAE majors take in the department. “We use the course as a retention tool,” he said. The objectives of the course are to apply microcomputer software useful in engineering analysis and reporting, to explore the use of computers and technology in solving problems in Biosystems Engineering and to become acquainted with Biosystems Engineering faculty, facilities programs and careers. “The students become more familiar with the people and the department, and eventually it will feel like a home to them,” Elliott said. The students in the class were required to complete a term project and a poster presentation in groups of three or four, Elliott said. Each group was given the opportunity to choose their topic from a list provided by Biosystems Engineering faculty.
“The teams came together well,” Elliott said. “So much engineering work is done in teams, and it was a learning experience about teamwork.” Some of the topics included changes in electrical conductivity during ohmic heating, weather influences on dead fuel moisture and probabilities for a working day in Oklahoma. A faculty consultant and a student consultant were assigned to assist each group. Class teaching assistant Erica Gaddis was also available to help when needed. The term project enabled each student to apply engineering software tools in the analysis of data and the reporting of results, gain experience in a team approach to problem solving, further develop communications skill, be exposed to “real world” applications of Biosystems Engineering and interact with faculty and students in the Biosystems and Agricultural Engineering Department, Elliott said. Each team presented a poster summary of their project to the department and invited guests at a reception
December 2, 1998. This reception included refreshments and a steady stream of people for about two hours, Elliott said. This was the first year the class was required to do a poster presentation, he said. “Poster presentations are becoming more common at technical meetings,” Elliott said. “It gave the students a more informal opportunity to display their work.” Elliott said each group gave high quality poster presentations and their ability to answer questions were excellent. Each group spent most of their time working on the term projects outside of class. Many groups divided responsibilities while coordinating and working together. The class is only offered in the fall and contains predominately freshman and a few junior college and on-campus transfers. “Looking back on it, most of them had a positive outlook about the class,” Elliott said.

Bioreactor process causes positive impact Converting low-cost feedstock into ethanol by means of a gasification/ bioreactor process is a new project at the department of Biosystems and Agricultural Engineering. This project is designed to obtain liquid fuel from low-cost biomass such as wheat straw and switchgrass, which has been a national objective since the energy crisis of the 1970s, said Ray Huhnke, Professor and Extension Agricultural Engineer in the Biosystems and Agricultural Engineering Department. “The plan is a holistic approach to a biomass energy conversion system that identifies alternative feedstocks that can be delivered to a commercial plant which then converts the biomass into ethanol using a gasification/bioreaction process,” Huhnke said. During this process, biomass is gasified at temperatures in excess of 120 degrees Fahrenheit to produce syngas, which is then converted to ethanol with a microbial catalyst. Huhnke said the project includes three main objectives: develop and demonstrate an integrated pilot gasifier/ bioreactor system; determine the characteristics of an optimized system for producing, harvesting, transporting, storing and processing the biomass
feedstock; and develop a design, an economic evaluation and an environmental impact assessment of a full-scale plant to convert biomass to ethanol. The use of low-cost biomass would be beneficial in the conversion to ethanol because of its availability and its potential to make use of waste products, Huhnke said. The Williams Company of Tulsa, industry partner and the nation’s second largest producer of ethanol, indicates that . the gasification/bioconversion process can theoretically produce 140 gallons of ethanol per ton of biomass, Huhnke said. The project team members are confident of getting at least 80 gallons of ethanol per ton on a conservative level and should definitely be able to obtain 100 gallons or more per ton, Huhnke said. Economic development in rural areas could be greatly enhanced by such a biomass energy system as poorly utilized land and agricultural residues are given economic value, Huhnke said. There would also be a positive environmental impact of using renewable energy resources, both on air quality and the global greenhouse problem, he said. “The project is significant because of the potential impact on global climate
change resulting from the accumulation of greenhouse gases in the atmosphere,” Huhnke said. “This is viewed as one of the world’s most serious environmental problems.” The principle investigator of the project is Dr. Charles Browning, former Dean of the Division of Agricultural Sciences and Natural Resources of OSU. Co-principal investigators are Drs. Randy Lewis, A.H. Johannes, Billy Barfield, Ray Huhnke, Danielle Bellmer, Tim Bowser, Charles Taliaferro and Francis Epplin from OSU and Dr. Ralph Tanner from the University of Oklahoma. This team of six engineers, an agronomist, an agricultural economist and a microbiologist will address several essential parts of the biomass energy system. Huhnke said the process becomes more economically attractive as oil prices increase and could help lead the nation to greater energy independence. “Over time, this process will become more competitive, and we will be less dependent of foreign oil,” he said. This on-going project will be completed in four to five years when most the critical questions have been answered, Huhnke said.
