At a meeting held on 26 November 2021, the Council of the University of the Free State (UFS) approved the awarding of the UFS Council Medal for outstanding service to Nico Janse van Rensburg, Senior Director: University Estates.

 

Building our campuses

Janse van Rensburg completed a BSc Quantity Surveying degree at the UFS in 1989 before joining the institution’s then Department of Physical Planning in 2004, after an impressive career as quantity surveyor. In 2012, he was appointed Senior Director: University Estates, continuously adding value to the infrastructure of our three campuses – totalling more than 500 000 m2 – as well as experimental farms and off-campus entities of more than 1 000 ha.

He has a persistent green approach that not only reduces the UFS’ carbon footprint, but also saves the institution millions of rands in energy savings and maintenance. Indigenous and waterwise gardens greet staff, students, and visitors to all our campuses, while being housed in well-maintained buildings. All newly built facilities on our campuses are based on green building principles, while an overall optimal building management system ensures efficient energy management.

 

Mentorship and skills transfer

University Estates, through its procurement management and the leadership of Janse van Rensburg, is also one of the main drivers behind the UFS’ BBBEE scorecard. He initiated a mentoring and skills transfer strategy by means of joint project appointments, enabling previously disadvantaged firms to eventually be appointed independently for similar projects.

To ensure, among others, aesthetically pleasing buildings that offer value for money, Janse van Rensburg and his team have developed a series of technical manuals that outline material specifications and expectations. Since 2012, he has been instrumental in more than 1 000 projects at the UFS.

The university recognises and commends Janse van Rensburg’s indispensable contribution to creating inclusive and quality spaces on our campuses, where staff, students, and visitors can experience our culture of care. His motto is clearly visible in all the projects he completes: Get things done – within time, budget, quality standards, expectations, and user satisfaction.

“It is an immense privilege to be leading the University Estates team, and I am humbled to be the recipient of this prestigious medal. University Estates is all about teamwork, and an award such as this can only be possible through the commitment, dedication, and support of a very capable team, as well as colleagues throughout the UFS. I would also like to thank our very capable leaders, such as Prof Prakash Naidoo, Vice-Rector: Operations, for his support and guidance. I have learnt a lot on this journey and a lot remains to be learnt. All of this could only be achieved with help that goes beyond one’s own strengths and abilities,” said Janse van Rensburg.”

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.
