Growing up on the family grain and cattle farm in Balfour, Mpumalanga, Danie Bester developed an interest in computers alongside a love for farming. This has benefitted him in an era of technology and precision farming, where GPS-linked systems and software programs have enabled him to optimise every square metre of his farm.
He also leans on a group of farmers in the US who share a common vision to obtain the maximum possible yield using the latest technology, their own research and shared learning.
“Being part of such a group has made a world of difference to the way I farm. I’m challenged to think differently about how we farm in South Africa, and question the norms,” says Bester.
NEW THINKING
One of the shifts he has made is how he views potassium application in maize and soya bean.
“What I learnt studying agriculture, and from farmers in the US, is that our entire approach to fertilisation is wrong. I’ve seen first-hand that [South Africa is] light years behind. Our fertiliser programmes need a makeover because the levels of elements, especially potassium, aren’t where they need to be. We’ve advanced when it comes to the seed genetics we use, but somehow the prescribed fertiliser norms have stayed the same down the years.
“Our potassium levels are traditionally much lower than those of farmers in the US. We’ve focused all our attention on the genetics in the seed, but as they change, they have new requirements. Potassium is a big driver of yield and because the improved genetics have more potential, they need more nutrients to sustain that potential. Current norms, which were published in 1992 and minimally revised in 2003, are about 52% lower than the latest published norms in the US, which are also lower than those being used by high-yielding growers.”

Understanding eye conditions in horses: causes and first aid
A horse can get a swollen eye from bumping it against a tree, shaking its head to keep flies away, or even snake venom
IPM requires a completely different mindset
You need to investigate any beneficial insects that may appear on your plants, or you can purchase them
Does parrot farming protect wild species?
Those in favour of commercial captive breeding argue that breeding parrots to sell can relieve pressure on wild populations. Researchers Neil D'Cruze and Rowan Martin review the evidence.
Bacterial and fungal diseases of garlic
Garlic can be prone to bacterial and fungal diseases, and it's important that farmers are proactive in preventing infection and practise appropriate management. Magda du Toit reports.
Responsible wastewater management: a crucial part of farming
The inadequate management of waste water is a challenge that the agriculture sector needs to deal with. Magda du Toit spoke to experts in waste and water management about a cost-effective treatment system.
Technology that can help protect South Africa's farms
Farm attacks, murders, livestock and crop theft, and other rural crimes are a growing concern in South Africa. As a result, more and more farmers are turning to advanced security technology to protect their lives, properties, and livelihoods. Sinenhlanhla Mncwango spoke to experts about the security strategies that producers can adopt to combat these threats.
The impact of theft on farms in South Africa
A high number of livestock are being stolen every year in South Africa. Insurance is expensive and farmers are battling to find solutions to the problem, says Dr Lindie von Maltitz, agricultural economics lecturer in the Faculty of Natural and Agricultural Sciences at the University of the Free State.
Staying afloat amid the cost-price squeeze
John Hudson, head of agriculture at Nedbank Commercial Banking, spoke to Glenneis Kriel about the importance of environmental and social sustainability for a prosperous agriculture sector.
Free State has no reason to mark Transport Month
Free State Agriculture (FSA) is very concerned about the extremely poor state of rural paved and gravel roads in the province and has very little, if anything, to celebrate during Transport Month, which takes place every October.
SA's food system ‘vulnerable to climate change'
The Just Transition Agenda for Food System Policymaking in SA webinar, hosted by the Institute for Economic Justice (IEJ) in October, highlighted the role that South Africa’s food system plays in contributing to climate change and how vulnerable it is to the impact thereof.
