Originating from the anthroposophy of Rudolf Steiner, biodynamics takes a holistic approach to viticulture. It’s regarded by some as the first modern ecological, yet sustainable farming system, and has much in common with other organic philosophies. Biodynamics emphasises the use of manures and composts, for example, and discourages artificial chemical programmes. But the biodynamic model also considers the farm itself as a single, self-sustaining organism. An injury to one part is an injury to all!
Wedderwill’s unique methods here include the use of fermented herbal and mineral preparations as compost additives. This is a groundbreaking concept, using the farm’s own resources – beefwood, vine and cane shoots, nettles, dandelion and other plants – to create an anti-fungal mix. It’s the first real alternative to the standard Bordeaux copper and sulphur solution. Wedderwill is currently running a trial study with the University of Stellenbosch.
Natural cycles – the balance of nature – isn’t a new idea. Farmers throughout the ages (including the Wedderwill founders’ Prussian ancestors 350 years ago) instinctively sought to work as harmoniously as possible with the environment. They had to ‘research’ through trial and error, but, today, technology is a powerful farming tool. Those who work at Wedderwill are keen users of cutting-edge techniques – but never forget ancient wisdom. It’s a powerful combination.
We now know that micro-organisms (fungi and bacteria) in the soil are key. They break down plant and animal material – the residue of the life-and-death struggles of insects, worms and so on – transforming it into a chemically-rich humus. This, in turn, means improved root growth and healthier vines. Pests, toxins and diseases are also naturally kept in check, with less call for any chemicals or fertilizers.
Fewer chemicals also lead to better quality groundwater. And, by reducing soil compaction, Wedderwill makes more efficient use of this water, too. Nature ensures that it’s retained where it’s needed, with less run-off and erosion.
To date, international research comparing biodynamics to other organic methods shows that biodynamics yields better crop results. There is also greater potential here for a truly sustainable farm with
an improved product, and a happier future for the next generation. The estate also follows an astronomical calendar, taking its planting and harvesting cues from the heavens.
