Soil Confrence at UFS
At the Combined Congress with the theme ‘Basic and applied sciences – Fundamentals of sustainable agriculture’, were from the left: Prof Klaus Kellner, Prof Prakash Naidoo, Dr Cobus Botha from the Agriculture Research Council, Prof Vaughan Hattingh, and Mr Matome Ramokgopa.

“We are at the beginning of a new decade that will in all likelihood be pivotal for aspects such as food security, climate change, and the sustainable use of natural resources – aspects that the societies you represent are of course keenly involved with – and in terms of which you can play an increasingly valuable role.” 

These were the words of Vice-Rector: Operations at the University of the Free State (UFS), Prof Prakash Naidoo, on opening a Combined Congress of the Soil Science Society of South Africa (SSSSA), the South African Society of Crop Production (SASCP), the Southern African Weed Science Society (SAWSS), and the Southern African Society for Horticultural Sciences (SASHS).

The UFS Department of Soil, Crop and Climate Sciences is hosting the congress, with scientific content of four disciplines (soil, crop, weed, and horticulture) presented by both local and international guest speakers.

The theme of this year’s congress taking place on the UFS Bloemfontein Campus, is Basic and applied sciences – Fundamentals of sustainable agriculture.

Prof Naidoo continues: “It has been predicted that the world will need almost double the current food supply by 2050 to feed an ever-increasing world population. This clearly makes the scientific work done in the agricultural sector and the organisations affiliated with it, more vital than ever. We need to do what we can to ensure food security and sustainability.”

“A congress like yours is an opportunity to tap into the perspectives and research results of collaborators from different fields, and from different levels of skill and experience – with the aim of ultimately benefiting wider communities.”

Leader in agriculture sector

Prof Vaughan Hattingh, representing SASHS (Chief Executive Officer of Citrus Research International); Mr Matome Ramokgopa, representing SASCP (General Manager of Enza Zanden SA); and Prof Klaus Kellner, representing SSSSA (Department of Botany at the North-West University), delivered the combined opening address.

Prof Hattingh, speaking on ‘Industry–University partnership opportunity road ahead for horticultural research’, says citrus is a major horticultural product internationally and the biggest horticultural export from South Africa. The citrus industry, the second largest exporter of citrus in the world, generates R20 bn per year and is the biggest funder of research in this area. 

Prof Hattingh states that university partnerships, developing science to assist the industry, are key. “The future of horticultural industries and horticultural research at universities depends on successful university-industry partnerships.”

Mr Ramokgopa talked about ‘Innovative solutions for vegetable seed production for a growing population’, saying that Enza Zanden employed several techniques in vegetable production in response to the needs of retailers and consumers. These include smaller tomatoes (for snacking purposes), smaller leaf size of lettuce (thus a smaller area for decay), plastic-free packaging of cucumber with a longer shelf life, and more uniform onions (suitable for onion rings). 

Prof Kellner focused on ‘Scientifically sound policies and practices to ensure food security and sustainable agriculture’. He said: “It is getting warmer in Southern Africa and Europe. We need to realise it and adapt practices accordingly.”

More discussions on sustainable agriculture

Other interesting topics covered at the congress include, ‘Developing propagation technologies for indigenous plants used in the natural products industry’; ‘The influence of foliar and application rate of nitrogen fertiliser on seed and oil yield of canola’; ‘Sweet potato production in sacks: potential utilisation of limited space in rural, urban and peri-urban areas’; ‘The efficacy of postharvest wax application in the reduction of chilling injury incidence in lemon fruit’; and ‘Herbicide use within the commercial forestry sector in South Africa’.

Congress attendees can also look forward to the ‘Soil fertility and crop nutrition symposium: principles and practices’ on Wednesday 22 January 2020.

The congress kicked off on 21 January, and will come to an end on Thursday 23 January 2020. For more information on the sessions, see programme.

Farmers need to plan grazing better, says UFS expert

“Farmers should save veld during the summer months to have grazing available for animals especially in the winter and early spring. Farmers should also adjust livestock numbers timely and wisely according to the available material in the field,” says Prof HO de Waal, professional animal scientist and affiliated researcher in the Department of Animal, Wildlife and Grassland Sciences at the University of the Free State.

He offered this advice as a result of the sporadic and scattered (scant) rainfall of the past couple of summers. “In retrospect we know that this kind of precipitation started in about 2014 and has continued in subsequent summers. In February 2015, it was clear that a major fodder scarcity was developing.”

Existing research methods serve as source of current knowledge
Dr Herman Fouché (Agricultural Research Council) has conducted research on the impact of climate, especially rainfall, on the growth of grass. Sophisticated computer technology developed as far back as the 1980s to – through modelling – predicts the impact of climate on field production during the growing season.

The impact of climate, and more specifically rainfall, on field production has been known to animal and grazing scientists for a long time. Prof De Waal used the modelling results to determine the impact of rainfall on grass as a feeding source for animals.

“Information that emerged from this old research programme could therefore be applied directly to animal production,” says Prof De Waal.

Adjust livestock numbers to availability of grazing
In the summer rainfall areas of South Africa, grass usually grows from the end of August and early September. The growth process is dependent on the transfer of soil moisture, as well as on rainfall during the winter and early spring.

“Livestock numbers should be balanced throughout the year (according to the nutritional needs and production of the animals) with the availability of grazing material – be consistent, not only during certain seasons or when drought is imminent,” is Prof De Waal’s advice to farmers. “Farmers are also encouraged to carefully reduce the number of livestock on grazing and to rather focus their attention and limited resources on the remaining breeding herds (cows and ewes).”

“It is tragic, but unfortunately many farmers will not survive the effects of recent years. Similar climatic conditions will occur, with the same tragic consequences for man and beast. Better planning has to start now.” The assistance of private institutions, individuals, as well as the government, during the severe droughts is gratefully acknowledged.

Spineless cactus pear as solution for scarcity of animal feed
Prof De Waal says spineless cactus pears could be used as a feeding source during droughts. “The effects of a severe drought, or major animal-feed scarcity, are still prevalent in large parts of the subcontinent.” This may act as a catalyst to utilise spineless cactus pears as a feeding source and to be incorporated in the feed-flow programme for livestock on natural grazing.
