The University of the Free State (UFS) recently hosted a landmark event-the national launch of the South African Biogeochemistry Research Infrastructure Platform (BIOGRIP) - in the Centenary Complex on its Bloemfontein Campus. This significant occasion marked the establishment of the Centre for Mineral Biogeochemistry at the UFS and underscored South Africa’s growing commitment to biogeochemistry research.

Prof Anthea Rhoda welcomed the distinguished gathering of scientists, students, industry leaders, and stakeholders, highlighting the launch as a collaborative milestone in South Africa's scientific journey. In her address, Prof Rhoda emphasised the importance of the interdisciplinary nature of biogeochemistry, where biology, geology, and chemistry converge to offer insights into critical issues such as climate change, water quality, and soil health. She remarked on the necessity of collaboration, explaining that BIOGRIP’s platform, built on shared resources and expertise, exemplifies the power of uniting across institutional boundaries to accelerate impactful discoveries.

The programme featured insightful scientific talks by leading experts, each focusing on how biogeochemistry addresses key environmental issues such as sustainability and resource management. These presentations reinforced BIOGRIP’s commitment to advancing knowledge that can influence policy and improve practices.

Attendees were also given guided tours of the state-of-the-art laboratories in the Centre for Mineral Biogeochemistry, which provided a behind-the-scenes look at the advanced tools and methods employed in studying interactions between minerals, biology, and the environment. For many, this was a highlight, as they observed firsthand how biogeochemical research is conducted and contributes to soil health, pollution control, and environmental conservation.

The launch provided ample networking opportunities, fostering connections among academics, government representatives, industry professionals, and environmental organisations. Over a catered lunch, participants engaged in vibrant discussions about potential collaborations and the role of biogeochemistry in addressing South Africa’s environmental challenges.

The BIOGRIP national launch stands as a milestone event, not only for the UFS, but for the broader South African scientific community. With the establishment of this research platform, South Africa is well-positioned to tackle pressing environmental issues through innovative research and cross-sector collaboration. The event left attendees inspired and motivated, setting an optimistic tone for the future of biogeochemistry research in the region.

Plant-strengthening agent enhances natural ability of plants to survive

2015-07-27

Drought, diseases, and fungi. These are factors that farmers have no control over, and they often have to watch despondently as their crops are damaged. In addition, the practice of breeding plants in special and strictly-controlled conditions, has resulted in crops losing the chemical ability to protect themselves in nature.

Researchers in the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS) have developed an organic agent that restores this chemical imbalance in plants. It enables the plant to build its own resistance against mild stress factors, and thus ensures increased growth and yield by the plant.

ComCat®, a plant-strengthening agent, is the result of extensive research by the German company, Agraforum AG, together with the UFS. Commercialisation was initially limited to Europe, while research was done at the UFS.

“Plants have become weak because they were grown specially and in isolation. They can’t protect themselves any longer,” says Dr Elmarie van der Watt from the department.

Dr Van der Watt says that, in nature, plants communicate by means of natural chemicals as part of their resistance mechanisms towards various stress conditions. These chemicals enable them to protect themselves against stress conditions, such as diseases and fungi (biotic conditions) or wind and droughts (abiotic 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.

The European researchers extracted these self-protection chemicals from wild plants, and made them available to the UFS for research and development.

“This important survival mechanism became dormant in monoculture crops. ComCat® wakes the plant up and says ‘Hey, you should start protecting yourself’.”

Research over the last few years has shown that the agent, applied mostly as a foliar spray, subsequently leads to better seedlings, as well as to growth, and yields enhancement of various crops. This is good news for the agricultural sector as 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.

“The use of synthetic agents, such as fungicides which contain copper, are now banned. Nowadays, options for natural and organic agriculture is being investigated. This product is already widely used in Europe, but because farmers are often swamped by quacks, the South African market is still somewhat sceptical.”
