Tanya von Berg
Tanya von Berg has represented the UFS netball team with distinction over seven years, winning three Varsity Netball titles and one USSA crown.

Although she did not quite reach her final goal in a Kovsie netball dress, being honoured one last time brought much peace to Tanya von Berg.

She was named in the Dream Team at the conclusion of the University Sport South Africa (USSA) tournament in Johannesburg and was thus recognised as the best centre at the competition.

According to the stalwart who played in her seventh year for the University of the Free State, her goal was to make this team and lift the trophy. The team didn’t succeed in the latter, losing to the North-West University in the semi-final.

Heading abroad
“Knowing that it would be the last time I would be playing for the team, I set myself these two goals. Although we were not able to claim the title, at least making the Dream Team helped to make me feel that I finished on a high, giving my all one last time,” she said.

Von Berg, who is doing her honours in Education this year, received a teaching post in Qatar, where she will start in August.

Remarkably this versatile player, who could play any one of four positions, only missed two matches in the two student competitions since making her debut as a first-year student in 2013. This was due to national commitments in 2016 (playing for South Africa A) and her honeymoon last year.

Standout moments
“Being named for the Protea training squad in 2016 and being selected for the national Fast5 team later that year, was the two outstanding moments of my career.”
“What I remember about my first year, was how huge it was to play with the seniors. The one player who served as my biggest inspiration, was Isélma Parkin. She didn’t receive the recognition she deserved. I learned from her to continue to work hard and to never give up.”

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.
