Biodynamic preparations are an integral part of our farming method. We use them specifically on the soil and plants. The two most important preparations are horn manure (500) and horn silica (501).
At our winery, the horn manure preparation is applied to the soil in November and again in spring. In contrast, horn silica is used during and following the flowering period, when the plant transitions from its growth phase (expansion phase) to the fruiting phase (concentration phase). We fertilise the soil in our vineyards with compost to which we add small amounts of preparations made from yarrow, oak bark, nettle, chamomile, dandelion and valerian.
Alongside our preparations, we utilise various infusions to proactively bolster our plants. These infusions, made from chamomile, horsetail, nettle, dandelion, valerian, willow, oak bark and yarrow, are sprayed on the plants. We also use compost teas.
During the autumn months, we sow various seeds between the vine rows. These plants develop roots at different depths, loosening the soil and creating habitats for earthworms and other soil microorganisms. The blossoming plants offer natural habitats for insects. Additionally, these plants provide biomass in spring, which we use for green manure.
This term may sound a little complicated, but it’s essentially made up of three Latin words: “ager” (field), “silva” (forest) and “pastor” (shepherd). This system combines the cultivation of crops with forestry and grazing lands for livestock. In recent years, we’ve put a greater emphasis on forestation alongside animal husbandry and growing grains. We’ve planted a variety of shrubs, aromatic plants, fruit trees and olive trees among our vines, even replacing some grapevines with other types of woody plants. When planting new vines, we now allocate ample space for trees. The trees and shrubs create habitats for birds and insects and provide shade for the soil. Last but not least, the fruit, nut and olive trees serve as an additional food source for both humans and animals.
We aim to care for our vines preventively and keep them as resistant as possible. In biodynamic viticulture, we do not use synthetic aids such as fungicides, insecticides, herbicides or synthetic mineral fertilisers. In extreme weather conditions, such as long periods of high humidity, it is possible to prevent fungal diseases by applying copper and sulphur. These substances, which only cover the surface of the leaves, are permitted in small quantities in biodynamic agriculture. While we are cautious about copper and sulphur, we are not yet in a position to do without them completely.
