The late Prof Jaap Durand.
The management of the University of the Free State (UFS) is saddened to learn of the passing of Prof Jaap Durand, revered theological academic and author. Prof Durand obtained his master’s degree from the UFS and received an honorary doctorate in Philosophy from the UFS in 2004.
Prof Durand has had a colourful career as academic, writer, and struggle activist: from Professor of Systematic Theology and Dean of the Faculty of Theology at the University of the Western Cape to Deputy Vice-Chancellor of the same university. He also served as the ombudsman of Stellenbosch University from 2002 to 2003.
During his life, Prof Durand was a unifier and a critical voice, speaking out against injustice. He has also authored several books, including Dit is amper dag; Evolusie, wetenskap en geloof, and Protesstem.
The UFS joins the higher education community in mourning and is deeply saddened by the loss of such a great theologian and academic. We wish to convey our deepest condolences to Prof Durand’s family, friends, and loved ones during this time.
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.
