As a public higher-education institution in South Africa with a responsibility to contribute to public discourse, the University of the Free State (UFS) will be presenting the 3rd UFS Thought-Leader Series in collaboration with Vrye Weekblad as part of the Vrystaat Literature Festival’s online initiative, VrySpraak-digitaal.
This year, higher-education institutions
globally are placed in the challenging context of COVID-19. Aware and grounded in the reality that the world will not return to the normality of pre-COVID-19, our responsibility as scholars still remains to contribute to public discourse and to offer
innovative solutions that will impact the lives of people nationally and globally in order to help them understand and adapt to a new world order.
Against this background and context, this year’s debates focus on ‘Post-COVID-19, Post-Crisis’,
with Health and Modelling, Politics, Economy, and Predictions for 2021 as the sub-themes. Placed in a COVID-19 context, and in lieu of the Vrystaat Arts Festival,
the series will be presented virtually in the form of one webinar per month during the period August 2020 to November 2020.
Date: 13 August 2020
Topic: Health
and Modelling
Time: 11:30-13:00

UFS teams up with Department of Agriculture and donates latest farming technology to Oppermans
Emerging and commercial farmers of the Oppermans Community in the Northern Cape will now be able to monitor the salinity levels on their farms effectively for the first time.
This is as a result of a donation of the latest technology that measures the salinity of soil – the EM38 system – which the University of the Free State (UFS) is donating to the community.
The unique project was launched by the Department of Soil, Crop and Climate Sciences at the UFS and the Department of Agriculture in the Free State during an information day held at Jacobsdal recently.
The day was attended by members of the Oppermans Community and representatives of the UFS as well as the Department of Agriculture. Mr Sugar Ramakarane, Head of the Department of Agriculture in the Free State, did the welcoming and several academics from the UFS held discussions about various topics related to the salinity levels in soil.
Since the establishment of the Oppermans Community emerging farmers are now for the first time able to accurately monitor the salinity levels on their farms as well as that of irrigation schemes of commercial farms in the area.
“In a region such as the Northern Cape it is very important that the salinity level of soil is monitored properly. As water is administered to crops, salts accumulate in the soil because the roots leave most of the salts in the soil when it transpires. When the salinity of soil increases, the osmotic potential thereof can also increase, which can seriously damage the water intake of crops and can create loss in yield and income,” said Prof. Leon van Rensburg from the Department of Soil, Crop and Climate Sciences at the UFS and leader of the Oppermans Project.
To assist the farming community of Oppermans to apply precision farming and to measure the salinity level of soil more accurately the latest technology that measures salinity in soil – the EM38 – will be donated to the community. Although the system is used throughout the world, the UFS is the only tertiary institution in the country that owns the latest version of this system.
“We are also training two persons from the Oppermans Community as technicians that will monitor the use of the system. The advantage of the donation of the system for the university is that we can gather data that can be used for research purposes by our Master’s and Doctoral students. We also want to see if water-table heights can be measured with this system,” said Prof. Van Rensburg.
According to him the system has several advantages for the community’s emerging farmers. “For the first time the salinity level of soil can now be measured accurately, salt maps can be drawn up, we can advise farmers about the corrections that need to be made and salinity management plans can be compiled,” he said.
The system is very accurate as it takes measurements every 200 mm while it is pulled by a four-wheel motorbike. The readings provide the distribution of salts up to a soil depth of 1 500 mm. “In the past the measuring of salinity levels was time-consuming and the cost thereof was R90 for one sample. The new system is more cost-effective,” stated Prof. Van Rensburg.
The instruments will be handed over to the African Spirit Group of the Oppermans Community, who will then become the owners. The service to farmers will then be managed by an operational group consisting of people from the Oppermans Community, a postgraduate student who can compile salinity maps and Prof. Van Rensburg, who will act as project leader and advisor.
The system will also be made available to farmers at the Riet River and Vaalharts Schemes.
