Plant protection
- abiotic by reducing the infection pressure through defoliation, halving of bunches, light and low foliage wall design
- Manual removal of infected leaves or parts of leaves
- Biotic through targeted application of the spray agent into the foliage wall using a battery-powered backpack sprayer with adjustable hand blower
- No dispersion of the spray mist into the environment thanks to the use of injector nozzles
- Indication based on the internet-based VITIMETEO platform, which uses regional agrometeorological weather stations and the local station network to calculate forecasts relevant to viticulture with regard to disease incidence and pest development
- If possible, without any application (2020, 2023)
- Only prophylactic use of milk (powdery mildew) and purely organic plant additives (downy mildew)
- Herbal extracts are used here, no conventional herbicides or pesticides
- the herbs applied preventively 48 hours before the expected infection event prime the vine as elicitors in such a way that it reacts more quickly to the pathogens in the sense of induced resistance and activates the plant's own immune defence mechanisms
- No use of chemically synthesised plant protection products
- No use of sulphur * (harmful to predatory mites, among others)
- No use of copper sulphate * (heavy metal intoxication of the soil, damage to the microbiome, no earthworms, especially harmful to wild bees)
Risk: in adverse weather conditions with high infection pressure, no quality crop or total loss
* both substances are authorised for organic and biodynamic viticulture up to an application rate of 3 kg/ha p.a. of copper sulphate and are used against powdery and downy mildew
Soil amelioration and fertilisation
- No large-scale mechanical tillage, thus no sealing horizons through compression
- No mulching
- Use of the brush cutter for selective grass cutting
- Formation of a humus cover layer
- Microbiological enrichment and diversification of the soil
- Promoting the spread of naturally occurring, site-adapted dry plants
- No threat to insects/small animals
- organic fertilisation with sheep's wool pellets
- selectively directly on the vine without including the wider under-vine area or the vine alley
- Mycorrhisation of the drilled vine roots with fungal mesh granules
- Support of the soil microbiome and aeration by spreading approx. 1500 earthworms/10 ares
Irrigation
- If necessary, make planting holes at the respective vine root with a 4cm diameter auger
- then selective irrigation of the individual vines as required using hose irrigation
- consequently only minimal water loss due to evaporation or unnecessary irrigation in the under-vine area
- by pump-free falling pressure from four cisterns of 8000 litres each
Wire systems
- Completely renewed installation of Corten stainless steel poles and wires
- visually unobtrusive fit into the surroundings
- deeper corrosion is prevented by the surface barrier layer
- no metal enters the soil (cf. zinc piles: 1.5kg/ha)
