Prof Johann Rossouw Inaugural lecture

For Prof Johann Rossouw from the Department of Philosophy, the Naval Hill Planetarium – a digital planetarium on a hill in the centre of a modern city, was the perfect place to deliver his inaugural lecture titled, The soul of the academy.

The message of his inaugural lecture was on “the form adopted by the contemporary university, which is so focused on the quantitative that the qualitative is neglected. The focus on training is so strong that the university no longer pays attention to the education of students”.

Prof Rossouw referred to the soul of the academy as the highest in humanity, especially the part which cannot be counted. He also referred to the words of Blaise Pascal in the 17th century: “The heart has its reasons of which reason knows nothing”.

“Do we understand any of this in the contemporary university? And do we still remember the earliest origins from which the academy originated; that Philosophy is the mother discipline of all other disciplines, and how all contemporary disciplines form part of a bigger, coherent entity?” he asked.

The inaugural lecture took place on 28 February 2019. Prof Rossouw has a C2-rating from the National Research Foundation, and it is thanks to him, among other things, that the Department of Philosophy is the only South African Philosophy department with modernity studies as its main focus.

At the end of 2018, he was promoted to Professor of Philosophy at the University of the Free State (UFS), and currently he serves as acting Head of Department. “Due to Prof Rossouw’s involvement, among other things, research on African philosophy, critical theory, postcolonial thinking, and tradition and modernity is conducted in the department,” Prof Heidi Hudson (Dean: the Humanities) said.

Prof Rossouw started his formal training in Philosophy at the age of 12, and in 1991 he obtained a BA degree majoring in Philosophy and Psychology at the University of Pretoria, with distinction. He obtained his MA degree, a critical study of apartheid on the basis of Michel Foucault’s thinking, at Unisa in 1998. In 2002, he obtained his DEA in Philosophy at the University of Lyon 3 under the leadership of Régis Debray, and in 2013 his PHD on the theological trail in Bernard Stiegler’s thinking at Monsh University (Melbourne), under Michael Janover.

In 2016, he won a prize from the South African Academy for Science and Culture for one of the best Afrikaans humanity articles published in 2015.

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.”
