Michelle Marais and Wian Visser
The UFS winners of the Old Mutual Agricultural Student of the Year Competition are Michelle Marais and Wian Visser.

The University of the Free State (UFS) once again produced winners at this year’s Old Mutual Agricultural Student of the Year competition. Michelle Marais, honours student in the UFS Department of Agricultural Economics, and Wian Visser, final-year BScAgric Agronomy student, were top scorers in the Agricultural Economics and Crop Production sections respectively. 

Learning from the best

Apart from the opportunity to compete in their field of study, Michelle and Wian also benefited from the expertise of industry leaders in agricultural economics, animal science, and crop production. They had the opportunity to learn from Dr John Purchase (Agbiz), Dr Dirk Strydom (Grain SA), and Gerhard Schutte (Red Meat Producers’ Organisation), who acted as industry partners and judges during the competition. 

Michelle always had a particular interest in the development of emerging farmers and plans on doing her master’s degree in Agricultural Economics, focusing on emerging wool farmers. “Beyond that, I hope to get an opportunity to work finding solutions to some of the problems facing development in agriculture,” she said. 

Wian also plans on completing his master’s. “Thereafter, I would like to enter the workforce and help the current and future producers to farm better in a changing environment. The ideal would be to remain in a research-oriented position while working full time,” he said. 

Participating with the UFS in this competition, were Stellenbosch University (producing the overall winner in the Animal Science section, Pieter Theron), the University of Fort Hare, North-West University, and the University of Pretoria. As with last year’s competition, the students first had to compete in an initial round at their respective universities, after which eleven finalists went through to the final round held during the ALFA expo at the Afridome in Parys. 

Rewarded for hard work

The winners were announced during a gala dinner at the expo. Besides a green blazer and R1 000 prize money, Michelle and Wian also received an Old Mutual investment portfolio worth R5 000. They furthermore gained exposure on Grootplaas and RSG Landbou and in Plaas Media’s magazines Veeplaas, Stockfarm, and FarmBiz.

According to Dr Frikkie Maré, Academic Head of the Department of Agricultural Economics (UFS), the Old Mutual Agricultural Student of the Year competition provides the ideal opportunity for universities to showcase the quality of their Agricultural students, and thus the quality of their teaching and research practices. 

He said: “In the two years that the competition was hosted, the UFS managed to win the Agricultural Economics and Animal Science divisions in 2018, and the Agricultural Economics and Plant Production divisions in 2019.  We have thus been able to win all three categories over the two years, which can only serve as an indication that the UFS is indeed one of the top Agricultural Science universities in the country.”

Preparing for the workplace

Wian and Michelle both agree that they have received more than just the exposure and funding. 

In her own words, Michelle described the value added: “This competition challenged me to become more aware of current events within the politics, policy, and economic development in the country and the influence on our specific industry. The opportunity to present my findings and opinions on current issues in agriculture to several industry leaders, challenged me to combine the theoretical knowledge gathered in my four years of study with my practical experiences. Applying it to real-world problems and finding possible solutions helped me to realise that I could not have asked for better preparation in the workplace.”

According to Wian, the competition presented him with the opportunity to develop his networking skills and a chance to express his opinion in a professional environment. “It broadened my perception on agriculture by exposing me to different entities in the agricultural community. I also saw different methods and approaches in the sector that I am not necessarily familiar with,” he said. 

Wian believes the UFS has one of the best agricultural faculties in the country and that staff put a lot of effort into preparing students for the world of work. “The Department of Agronomy encourages critical thinking, an essential skill in an ever-changing work environment,” said Wian. He added: “Assessments are not only theoretical, but practical. These practical skills are related to the work required in a work environment. The department also exposes its students to companies, resources, and contacts that are helpful for networking when one enters the workforce.”

According to Michelle, the Department of Agricultural Economics also play their part in preparing students for the job market. “Our assignments always challenged us to contact people in the industry, to do industry research, and to plan practically,” she said. 

Old Mutual has been involved as the name sponsor of this Plaas Media competition since 2018 and has played an active role in promoting and developing the competition.

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
