Scie-Ed building

The university is transforming its campus with state-of-the-art infrastructure development. We are creating spaces that foster learning, empower groundbreaking research, and offer an enriching university experience.

UFS Sasol Library

The UFS has been hard at work to move away from traditional library spaces towards creating tech-enhanced, flexible environments that are dynamic for teaching and learning. According to Jeannet Molopyane, Director of Library and Information Services, they strive to align their spaces with global best practices with the infrastructure changes.

Centre for Mineral Biogeochemistry

The Centre for Mineral Biogeochemistry – completed in February 2023 – integrates seamlessly with its surrounding environment, while also providing a new collaborative workspace for the centre’s personnel. This state-of-the-art facility boasts various laboratories which were mainly funded by the Department of Science and Innovation (DSI). The CMBG includes, among other initiatives, the Mineral Node of the Biogeochemistry Research Infrastructure Platform (BIOGRIP), an initiative of the DSI. This space is situated next to the existing Microbiology Building on the Bloemfontein Campus. 

University Estates Building

For this repair and renovation project, with a construction theme, internal and external materials were selected for their low-maintenance qualities. The first office, located opposite the entrance door, features cladding with exposed galvanised corrugated iron. A new steel mezzanine level was installed and painted in ‘CAT’ yellow and black. All pipes, including plumbing and electrical, are exposed on wall surfaces. The use of internal exposed brickwork, concrete floors, and oriented strand board in ceilings and cupboards further accents this quality in the completed project. 

Animal Research Centre

The Animal Research Centre on the Qwaqwa Campus, replaced the temporary structure that previously served as animal housing. The new structure complies with the requirements and standards for a research facility and caters to the needs of researchers and animals, including small and large rodents. The exterior materials used complement those of the surrounding buildings, providing a low-maintenance profile. The building, accessible to persons with disabilities, contains two research laboratories, an ecotoxicology laboratory, a veterinarian’s office, and a procedure room.

South Campus 24/7 Study Space

The shift to extended programmes and dramatic increase in student enrolment on the South Campus created the need for additional study areas. Considering the steep site outcrop and the existing pedestrian routes from the lower campus, the design explored building blocks that progressively staggered up the hill to accommodate a small amphitheatre study area, maximising seating capacity. This allows the building to accommodate the site’s steepness rather than ignore it. The final design provides study spaces on three levels, all accessible via a ramp, with the main functions situated on the primary level. This design also ensures accessibility for all users, including those with disabilities.

KovsieGear

Incline Architects has designed a new innovative space on the Thakaneng Bridge on the Bloemfontein Campus to accommodate the expansion of the KovsieGear outlet. This new design incorporates extra retail space along with additional room for administration work. The KovsieGear shop now features a new aesthetic, created with natural materials to complement the UFS colours.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
