The University of the Free State (UFS) Wool Wise Community Project was recognised for its innovative use of wool, receiving accolades at the OVK Innovation Competition held in conjunction with the Karoo Winter Wool Festival in Middelburg from 13–16 June 2024.According to Carien Vorster, project manager from the Department of Sustainable Food Systems and Development, participants were tasked with crafting practical items from wool. Their creativity shone through in their design of a lampshade, earning them second place. Doretha Jacobs, a lecturer in the Department of Sustainable Food Systems and Development, focused on making felt from Dorper fibre, noting that while Dorper sheep are primarily bred for meat, they sought to repurpose fibres that would otherwise be discarded.

The team achieved third place with their cushion, featuring a front made entirely of merino wool felt and a back crafted from upholstery fabric. “Each cushion contains a 100% duck feather inner, and their uniqueness lies in the hand-dyed wool and hand-placed designs on each felt piece,” explains Vorster.

Other notable entries from different teams included a duvet inner, shoe insoles, and oven gloves. The top prize went to a hand-felted coat.

Community project empowers local women in wool craft

The UFS Wool Wise Community Project originated as a spin-off from the Regional Universities Forum for Capacity Building (Ruforum) project, initiated in 2019 by the UFS Department for Sustainable Food Systems and Development.

According to Vorster, the Ruforum project encompasses various components such as research, farmer support, and community development, with a particular emphasis on community upliftment programmes. "Since 2019, we have conducted numerous wool workshops and training sessions where local women have participated to learn about wool processing," she explains.

"From these events, we identified women who are now integral to our programme. Their skills range from sewing, felt making, and hand embroidery, to knitting."

The project features eight women who create diverse products from scratch: Elizabeth Mnwana, Emily Segame, Georgina Collins, Maserame Sebonyane, Nelly Olayi, Sarah Lenong, Sophia Mekhoe, and Ntabiseng Ndabeni.

She emphasises that the project also manufactures conference bags for various events and stands as one of UFS's most successful community initiatives. "Ultimately, this project has the potential to become self-sustaining, with proceeds supporting the salaries of the eight women," Vorster concludes.

Competition boosts visibility and market reach

Participating in initiatives like the OVK Innovation Competition motivates them to stay current and benchmark their efforts against other businesses or individuals involved in felt product creation.

"Winning a competition can also significantly uplift team morale," remarks Vorster.

"Securing second and third place in this competition translates to increased visibility and marketing opportunities for us. This is crucial as we aim to expand our market reach and establish a sustainable income stream for the project," she concludes.

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.
