During October, the national focus is on mental health. Mental Health Awareness Month also coincides with a time when our students prepare for the end of the year exams, making it a particularly valuable time for us to think about how we can continuously assist them during their time at university. The value of peer support and genuine care can never be overstressed; that is why I want to encourage our students to reach out to their support networks such as our Department of Student Counselling and Development, as we move towards the end of the year.
Mental health is an equally important matter for our staff. During this month, I want to encourage our staff to also take cognisance of their own well-being. There is a lot of wisdom in the old adage: Healthy body, healthy mind. Many of the initiatives of our Division of Organisational Development and Employee Wellness are focused on the value of physical activity and the negative impact that inactivity can have on one’s productivity and mental health. They also present regular lunch-hour sessions for our staff, where experts share information and practical tips for mental wellness. I want to encourage our staff to attend these sessions and to make use of the services the university has to offer in this regard. It is important to note that suffering from mental and anxiety disorders is not weaknesses and it is not always indicative of a deeper psychological issue; it is an illness and hence can be treated.
On 20 September 2019, a 21-member team was sent off on their run of 1 075 km to Stellenbosch to raise awareness for mental health. The run was organised by the Division of Organisational Development and Employee Wellness and the Faculty of Health Sciences. The team ran in relay format throughout the night and handed the baton of hope to Stellenbosch University on 25 September 2019. I admire and thank them not only for their commitment and stamina, but also for addressing this crucial matter in the public domain and for raising awareness in the many towns and communities along the way.

Plant eco-physiologist finds effective solutions for crop optimisation
2016-07-24
The bio-stimulant was tested on
this citrus. This is the first time
that the product has been tested
on a crop.
In a time characterised by society facing increasing population growth, food crises, and extreme climatic conditions such as drought, it is essential for farmers to integrate science with their work practices in order to optimise crops.
Role of photosynthesis and plant sap data
By knowing how to use photosynthesis and plant sap data for determining plant health, fast and effective solutions could be established for the optimisation of crops. This technique, which could help farmers utilise every bit of usable land effectively, is the focus of Marguerite Westcott’s PhD study. She is a junior lecturer and plant eco-physiologist in die Department of Plant Sciences at the University of the Free State.
Westcott uses this technique in her studies to prove that a newly-developed bio-stimulant stimulates plants in order to metabolise water and other nutrients better, yielding increased crops as a result.
Agricultural and mining sectors benefit from research
The greatest part of these projects focuses on the agricultural sector. Westcott and a colleague, Dr Gert Marais, are researching the physiology of pecan and citrus trees in order to optimise the growth of these crops, thus minimising disease through biological methods. Field trials are being conducted in actively-producing orchards in the Hartswater and Patensie areas in conjunction with the South African Pecan Nut Producers Association (SAPPA) amongst others.
The principles that Westcott applies in her research are also used in combination with the bio-stimulant in other studies on disturbed soil, such as mine-dump material, for establishing plants in areas where they would not grow normally. This is an economical way for both the agricultural and mining sectors to improve nutrient absorption, stimulate growth, and contribute to the sustainable utilisation of the soil.
The bio-stimulant contributes to the immunity of the plants.
It was tested in these pecan nut orchards (Hartswater).
Soil rehabilitation key aspect in research projects
“One of two things is happening in my research projects. Either the soil is rehabilitated to bring about the optimal growth of a plant, or the plants are used to rehabilitate the soil,” says Westcott.
Data surveys for her PhD studies began in 2015. “This will be a long-term project in which seasonal data will be collected continuously. The first set of complete field data, together with pot trial data, will be completed after the current crop harvest,” says Westcott.
