Jeanri-Tine respected for her word on wine
Jeanri-Tine

Jeanri-Tine van Zyl may have the perfect career – an idyllic lifestyle that most of us only dream of. She is her own boss and is required to drink wine on the job! Jeanri-Tine is a respected wine writer. She obtained a BA Media Studies degree at Kovsies, before completing further qualifications in Stellenbosch and Cape Town. She is the owner/director of Feed That Bird Communication Consultants (Pty) Ltd. – a PR, communications and content marketing agency providing creative communication support to some of South Africa’s major wine brands and companies. 

My favourite career quote is by Charles Bukowski: “If you're going to try, go all the way. Otherwise, don’t even start. This could mean losing girlfriends, wives, relatives and maybe even your mind. It could mean not eating for three or four days. It could mean freezing on a park bench. It could mean jail. It could mean derision … And, you'll do it, despite rejection and the worst odds. And it will be better than anything else you can imagine.” 

“I didn’t realise it at the time,
but those three years at the
UFS were probably some of
my best, most formative years.”

The best career advice I got was probably from well-known wine critic Michael Fridjhon, who told me a story about an exceptionally talented ballerina who gave up ballet when she wasn’t cast as the lead in ‘Giselle’ It might not be what he intended, but I interpreted it as ‘if you can’t be the best in what you do, quit and try something else’.

I didn’t realise it at the time, but those three years at the UFS were probably some of my best, most formative years. I remember the sleepless weekends as IRAWA editor, marching into Ds Kiepie Jaftha’s office armed with demands for better security on campus, the endless wisdom and strength shared by Dr Elsabe Pepler, who was head of Communication at the Department at the time, and sitting on the grass with my friends before a test, knowing that no matter the outcome, we will all be okay…

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.
