Crystal-Donna Roberts, recipient of the 2016 Kovsie Ambassador Award and award-winning actress, has died following a battle with breast cancer.
The University of the Free State (UFS) is deeply saddened by the passing of alumna and award-winning actress Crystal-Donna Roberts at the age of 41. According to Eyewitness News (EWN), Roberts passed away during the early hours of 6 March 2025, following a long battle with breast cancer.
The UFS extends its deepest condolences to Roberts’ family, friends, colleagues, and supporters.
Celebrating a beloved actress
Roberts graduated from the UFS with a BA Drama and Theatre Arts degree in 2005 and went on to create work that was beloved across the country and beyond. She starred in the Afrikaans soap opera 7de Laan and shows like Getroud Met Rugby, Montana and Vallei van Sluiers, among others. Her lead role in the film Krotoa earned her the Best Actress award in 2018 at the South African Film and Television Awards (SAFTAs).
Her extensive career in film and television was one of the reasons she was recognised by the UFS with the Kovsie Ambassador Award in 2016. This is an award given to alumni whose accomplishments have not only benefited themselves but their community and the UFS. Although Roberts was well-known for her work on stage and screens, she was also an author. She released her debut novel Speurder Sammi: Die blou steen (Detective Sammi: The Blue Stone) in 2022.
Outpouring of praise
Since the news of Roberts’ passing broke, there has been an outpouring of tributes on social media. Many of her supporters and colleagues have described her as an iconic force who was full of life and inspired many. Alistair Izobell, who starred alongside Roberts in Arendsvlei, responded to the news through a Facebook post which said, “My dearest sister Crystal-Donna Roberts my heart is broken today. You got your wings and your pain is no more. I am thrilled I got to do a chapter of my life with you. I will remember you with the great spirit you were. Now rest sweetly.”
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.
