The composition of the UFS Council is stipulated in the UFS Statute, which was published in the Government Gazette on 26 January 2018 and amended by publication in the Government Gazette on 29 March 2019.

The Convocation has to elect two (2) external (neither employees nor students of UFS) representatives to the Council to represent the Convocation and Alumni on Council, following the expiry of the term of office of these representatives.  The two (2) elected representatives will serve for a period of four years on Council.

The Convocation comprises all persons who obtained a formal qualification from the UFS, as well as all permanent academic staff members.

Members of the Convocation are invited to submit written nominations by using the Nomination Form, for the following:

1.    one representative from the Qwaqwa Campus; and
2.    one other representative.

Every nomination form shall be signed by 4 (four) members of the Convocation and shall contain the written acceptance of the nomination by the nominee under his/her signature, as well as an abridged CV and a motivation of ± 200 words.

All nominations must reach the office of the Registrar no later than 16:30 on Tuesday, 17 September 2019.

If more than one person is nominated for each of the categories mentioned above, elections will be held as stipulated in the Institutional Rules. More information regarding this process will follow at that stage.

Nominations are to be submitted to:
e-mail: registrar@ufs.ac.za

or by post (strongly advised not to use this method due to delays):

Mr NN Ntsababa  
Registrar
University of the Free State
PO Box 339
Bloemfontein

or hand-delivered to:                

Mr NN Ntsababa
Room 51, 1st Floor
Main Building

Well-established root system important for sustainable production in semi-arid grasslands

The importance of a well-established root system for sustainable production in the semi-arid grasslands cannot be over-emphasised.

A study of Prof Hennie Snyman from the Department of Animal and Wildlife and Grassland Sciences at the University of the Free State is of the few studies in which soil-water instead of rainfall has been used to estimate above- and below-ground production of semi-arid grasslands. “In the past, plant ecological studies have concentrated largely on above-ground parts of the grassland ecosystem with less emphasis on root growth. This study is, therefore, one of the few done on root dynamics in drier areas,” said Prof Snyman.

The longevity of grass seeds in the soil seed bank is another aspect that is being investigated at present. This information could provide guidelines in grassland restoration.

“Understanding changes in the hydrological characteristics of grassland ecosystems with degradation is essential when making grassland management decisions in arid and semi-arid areas to ensure sustainable animal production. The impact of grassland degradation on productivity, root production, root/shoot ratios, and water-use efficiency has been quantified for the semi-arid grasslands over the last 35 years. Because of the great impact of sustainable management guidelines on land users, this study will be continuing for many years,” said Prof Snyman.

Water-use efficiency (WUE) is defined as the quantity of above- and/or below-ground plant produced over a given period of time per unit of water evapotranspired. Sampling is done from grassland artificially maintained in three different grassland conditions: good, moderate, and poor.

As much as 86, 89 and 94% of the roots for grasslands in good, moderate and poor conditions respectively occur at a depth of less than 300 mm. Root mass is strongly seasonal with the most active growth taking place during March and April. Root mass appears to be greater than above-ground production for these semi-arid areas, with an increase in roots in relation to above-ground production with grassland degradation. The mean monthly root/shoot ratios for grasslands in good, moderate, and poor conditions are 1.16, 1.11, and 1.37 respectively. Grassland degradation lowered above- and below-ground plant production significantly as well as water-use efficiency. The mean WUE (root production included) was 4.79, 3.54 and 2.47 kg ha -1 mm -1 for grasslands in good, moderate, and poor conditions respectively.

These water-use efficiency observations are among the few that also include root production in their calculations.
