The Centre for Mineral Biogeochemistry (CMBG) at the University of the Free State’s (UFS) support and partnership of the Tritech National Science and Technology Fair reached new heights this year with the event set to be featured in a new television series.

CMBG has been a proud sponsor and partner of the Tritech National Science and Technology Fair for the past four years. Established in 2008, Tritech is a renowned competition that allows Grade 7 to Grade 12 learners from across South Africa to showcase their research abilities. The Tritech National Science Competition serves as a beacon of opportunity for young minds, fostering their passion for scientific exploration and igniting their curiosity. It is designed to enhance scientific literacy, encourage innovation, and nurture the next generation of scientists and inventors.

“The CMBG has consistently demonstrated its commitment to promoting education and empowering young individuals. As a result, we have partnered with Tritech since 2021, and I believe that this partnership has opened new doors and possibilities for our young scientists. We are incredibly honoured to be part of such a dynamic and inspiring environment,” said Dr Mariana Erasmus, Vice Director: CMBG and Tritech EXCO member.

Power of science and technology

According to Dr Erasmus, at the CMBG, they believe in the power of science and technology to transform our world. Their involvement in this event aligns perfectly with the centre’s commitment to fostering innovation, encouraging critical thinking, and nurturing the next generation of scientists and innovators.

“We are excited about the opportunities Tritech presents to the university to engage with cutting-edge projects, to exchange ideas, and build lasting collaborations. The spirit of curiosity and exploration that Tritech embodies is exactly what drives our institution’s mission forward.”

In addition to assisting with the judging of projects during the National Science Competition at the Merensky Agricultural Academy in Tzaneen, the CMBG presents a fun but intellectually stimulating activity, showcasing various STEM-related disciplines that UFS offers to inspire students from across South Africa to celebrate scientific discovery. Each year, the CMBG collaborates with a different department for these activities, and this year, in October 2024, the collaboration was with the UFS Department of Chemistry.

‘Science Olympics’

The theme for Tritech 2024 was “Science Olympics”, and after the formalities of the project presentations were completed, the fair kicked off with a grand procession led by bearers of flaming torches and flags reminiscent of Olympic ceremonies. “Learners marched proudly, symbolising their commitment to science, with representatives from UFS and Tritech EXCO leading the way, an unforgettable visual display honoured the learners’ passion for exploration,” said Dr Erasmus.

The event transitioned into a video presentation explaining the misuse of performance-enhancing drugs in sports, followed by interactive activities focused on analysing possible doping agents. Thereafter, the UFS team guided learners through hands-on experiments, demonstrating the science behind identifying performance-enhancing drugs. Through engaging, real-world applications, learners were not only able to detect these substances but quantify their findings, making the learning experience both fun and educational.

As the night closed, the Chemistry team mesmerised the audience with a ‘magic show’. Explosions of colour, booming sounds, and flashes of light filled the sky, leaving everyone in awe. The show combined entertainment and chemistry, showcasing the wonders of science through spectacular reactions.

On TV

The fair concluded the next day with activities like kart building and livestock showcases, ending with a prize-giving ceremony to reward the learners for their hard work throughout the year. Adding to the excitement, the event is set to be featured in a new television series, with the pilot episode filmed during the weekend of Tritech Nationals 2024.

“The series promises to bring the Tritech experience to life for a wider audience, aiming to capture the incredible spirit, creativity, and innovation that defines Tritech. It will be an incredible opportunity to gain recognition, inspire others, and highlight the importance of science and technology in solving real-world challenges,” Dr Erasmus concluded.

This year’s fair was a celebration of knowledge, creativity, and the endless possibilities of science, leaving a lasting impact on all who attended.

Plant-strengthening agent a result of joint effort between UFS and German company
2015-07-27

Research over the past few years has showed that the agent applied mostly as a foliar spray subsequently leads to better seedlings as well as growth and yield enhancement of various crops.

The application of a plant-strengthening agent in the agricultural industry has, until recently, been largely ignored, says Dr Elmarie van der Watt of the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS). The agent was co-developed by researchers at the UFS and a German company.

The product is moving into new markets, such as China, Vietnam, the USA, and Australia.

ComCat® was the result of extensive research by the German company Agraforum AG. Commercialisation was limited initially to Europe, while research was expanded to other parts of the world, with the University of the Free State as the main research centre.  ComCat® is a unique, non-toxic plant strengthening agent derived from wild plants. It enhances plant growth and yield, as well as resistance against abiotic and biotic stress factors.

Dr Van der Watt says that, in nature, plants communicate and interact by means of allelochemicals (the inherent silent tool of self-protection among plants) and other phytochemicals (chemical compounds that occur naturally in plants), as part of their resistance mechanisms towards biotic and abiotic stress conditions.

Most wild-plant varieties are usually well-adapted to resist these stress factors. However, monoculture crops have lost this ability to a large extent. “Active compounds contained in extracts from wild plants applied to monoculture crops can potentially supply the signal for the latter to activate their dormant resistance mechanisms.” 

Research over the past few years has showed that the agent applied mostly as a foliar spray subsequently leads to better seedlings as well as growth and yield enhancement of various crops.  A major advantage is that, despite its enhancing effects on root development and yield, it does not induce unwanted early vegetative growth that could jeopardise the final yield, as happened in the past for nitrogen application at an early growth stage. 

Dr Van der Watt says, “Physiological data on the effect of the natural bio-stimulant product on photosynthesis, respiration, and resistance towards biotic stress conditions indicate that it can be regarded as a useful tool to manipulate agricultural crops. Research also showed that the field of application for this natural product is never-ending, and new applications are being investigated every day.”
