Xylella fastidiosa HOST: GRAPEVINE What is Xylella fastidiosa and why is it so serious? ◆ A dangerous bacterium threatening hundreds of species of plants in the UK ◆ It is spreading across southern Europe from its origins in the Americas ◆ Can be transported by sap-feeding insects such as spittlebugs ◆ Causes plant death by blocking water transporting vessels (xylem) ◆ Currently no cure Vitis vinifera ◆ Deciduous climbing shrub ◆ Flaky bark ◆ Climbs by tendrils reaching 15–18m high ◆ Three- or five-lobed, coarsely toothed leaves, 7.5–15cm long and wide, with stalks half as long as the blade, hairy underneath and of variable colour ◆ Tiny greenish flowers ◆ Oval or globose fruit Healthy Diseased What is BRIGIT?

This soil has formed from B Horizon - Subsoil long term weathering of granite into soil like materials. C Horizon (deeper) Native Forest Soil Leaf litter and roots (> 5 T/Ac/year are “bio- processed” to form humus, which is the dark black material seen in this topsoil layer. In the process, nutrients and energy are released to plant uptake and the higher food chain. These are the “natural soil cycles” that we attempt to manage today. Soil Profiles Soil profiles are two-dimensional slices or exposures of soils like we can view from a road cut or a soil pit. Soil profiles reveal soil horizons, which are fundamental genetic layers, weathered into underlying parent materials, in response to leaching and organic matter decomposition. Fig. 1.12 -- Soils develop horizons due to the combined process of (1) organic matter deposition and decomposition and (2) illuviation of clays, oxides and other mobile compounds downward with the wetting front. In moist environments (e.g. Virginia) free salts (Cl and SO4 ) are leached completely out of the profile, but they accumulate in desert soils.

Late Harvest
TASTING NOTES LATE HARVEST DESCRIPTION 2017 The Tokaj legend has grown and grown in its four-hundred years of history; but it was not until 1630, when the greatness of Oremus vineyard was first spoken of. Today, it is the one with greatest universal acclaim. The Tokaj region lies within the range of mountains in Northeast Hungary. Oremus winery is located at the geographical heart of this region. At harvest, bunches are picked several times a day but. Only those containing at least 50% of botrytis grapes, are later pressed, giving the noble rot a leading role. Late Harvest is an interesting coupage of different grape varieties producing an exceptionally well-balanced wine. Fermentation takes place in new Hungarian oak barrels (136- litre “Gönc” and 220-litre “Szerednye”) for 30 days and stops naturally when alcohol level reaches 12 %. Then, the wine ages in Hungarian oak for six months and sits in bottle for a 15-month ageing period. Late Harvest is a harmonious, fresh, silky wine. It is very versatile, providing a new experience in each sip. GENERAL INFORMATION Alcohol by volume - 11 % Sugar - 119 g/l Acidity - 9 g/l Variety - Furmint, Hárslevelü, Zéta and Sárgamuskotály Average age of vineyard - 20 years Vineyard surface area - 91 ha Planting density - 5,660 plants/ha Altitude - 200 m Yield - 1,300 kg/ha Harvest - 100% Hand-picked in 2-3 rounds from late September to early November 2017 VINEYARD CYCLE After the coldest January of the past decade, spring and summer brought average temperatures and precipitation in good dispersion. Mid-September rain allows the development of noble rot to spread in the vineyard, turning 2017 into one of the greatest vintages for sweet wine in the last decade. -

Beeinflussung der Most- und Weinzusammensetzung Z u sam menfa ss u n g : Bei der Rebsorte Shiraz wurde das Ausmaß der Beschattung innerha lb der Laubwand künstlich durch vier Behandlungsformen sowie natürlicherweise durch e ine n Wachstumsgradienten variiert. Beschattung bewirkte in den Traubenmosten eine Erniedri gung de r Zuckergehalte und eine Erhöhung der Malat- und K-Konzentrationen sowie der pH-Werte. Die Weine dieser Moste wiesen ebenfalls höhere pH- und K-Werte sowie einen venin gerten Anteil ionisierter Anthocyane auf. Statistische Berechnungen ergaben positive Korrelatio nen zwischen hohen pH- und K-Werten in Most und Wein einerseits u11d der Beschattung der Laubwand andererseits; die Farbintensität sowie die Konzentrationen der gesamten und ionisier ten Anthocyane und der Phenole waren mit der Beschattung negativ korreliert. Zur Beschreibung der Lichtverhältnisse in der Laubwand wurde ei11 Bonitierungsschema, das sich auf acht Merkmale stützt, verwendet; die hiermit gewonne nen Ergebnisse korrelierten mit Zucker, pH- und K-Werten des Mostes sowie mit pH, Säure, K, Farbintensität, gesamten und ionj sierten Anthocyanen und Phenolen des Weines.

Biochar application to soil proves to be a suitable solution to these problems. Although the literature presents the pros and cons of biochar application, very little information is available on the impact of repeated application. In this study, we evaluate and discuss the effects of initial and reapplied biochar (both in rates of 0, 10, and 20 t ha−1) combined with N fertilization (at doses of 0, 40, and 80 kg ha−1) on soil properties and N O emission from Haplic Luvisol in the temperate climate zone (Slovakia). Results showed that 2 biochar generally improved the soil properties such as soil pH(KCl) (p ≤ 0.05; from acidic towards Citation: Horák, J.; Kotuš, T.; Toková, moderately acidic), soil organic carbon (p ≤ 0.05; an increase from 4% to over 100%), soil water L.; Aydın, E.; Igaz, D.; Šimanský, V. -
