An active and diverse soil biota is important for maintaining crop productivity quality, preservation of these traits a major goal sustainable farming. This study aimed at unravelling the impact different management practices on fungal bacterial biodiversity in vineyards as model permanent crops. Species diversity was assessed using an amplicon sequencing approach long-term field experiment Rheingau wine region Germany where integrated, organic biodynamic had been place 10 years. Fungal...

Abstract Successful containment strategies for the SARS-CoV-2 pandemic will depend on reliable diagnostic assays. Point-of-care antigen tests (POCT) may provide an alternative to time-consuming PCR rapidly screen acute infections site. Here, we evaluated two tests: STANDARD™ F COVID-19 Ag FIA (FIA) and Rapid Antigen Test (RAT). For assessment, used a large set of PCR-positive PCR-negative respiratory swabs from asymptomatic symptomatic patients health care workers in setting University...

Interest in sustainability has increased significantly the wine sector past few years, driven by customer interest, as well impact of global warming-intensified weather extremes on growers. For a sustainable future industry must design its entire value chain such ways that it conserves and regenerates natural environment at same time promotes human rights, inclusion equality. The current paper identified five key challenges which have to be overcome order reach this goal: (1) climate change...

The main objective of this study was to determine growth, yield and fruit quality grapevines under organic biodynamic management in relation integrated viticultural practices. Furthermore, the mechanisms for observed changes were investigated by determining nutrient status, physiological performance plants disease incidence on bunches three consecutive growing seasons. A field trial (Vitis vinifera L. cv. Riesling) set up at Hochschule Geisenheim University, Germany. treatment managed...

Grapevine (Vitis vinifera L.) expresses different responses to water stress, depending not only on genotype, but also the influence of vineyard growing conditions or seasonality. Our aim was analyse effects drought response two grapevine cultivars soils, one draining (WD) containing sand 80% volume and other retaining (WR), with no sand. Under these water-holding capacities Syrah, displaying a near-anisohydric Cabernet Sauvignon (on contrary, near-isohydric) were submitted stress in pot...

Demand for organically grown crops has increased exponentially in the last few decades. Particularly wine sector, organic and biodynamic management systems are gaining more importance, with some of most prestigious wineries converting to or viticulture. The purpose this study was review evidence comparing effects conventional, organic, viticulture on soil properties, biodiversity, vine growth yield, disease incidence, grape composition, sensory characteristics, quality. Only studies...

Aim: The aim of this study was to investigate the effects integrated (INT), organic (ORG) and biodynamic (BD) management systems with similar C- N-inputs on soil microbiology in a viticultural long-term field trial.Methods results: Within comparison, samples were taken 10 years after conversion, throughout growing season. To gather information about microbial community structure, activity five enzymes measured, phospholipid fatty acids (PLFA) neutral lipids (NLFA) profiles analysed...

Abstract There is growing interest in the application of sustainable agricultural methods to minimize environmental impact farming and thus aiding quantification actual benefit that such approaches may confer. We applied DNA metabarcoding with aim exploring how diversity fungi arthropods were affected by different management systems (integrated, organic, biodynamic) at experimental vineyard Geisenheim (Rheingau, Germany). Data generated for bloom harvest periods 2017, using (eDNA) analysis...

Vineyard soils show an increased risk of degradation due to being intensively cultivated. The preservation soil integrity and fertility is a key concept organic biodynamic farming. However, both systems are also subject criticism their higher amount plant protection products used traffic intensity compared integrated viticulture, detrimental quality. aim this study was therefore assess long-term effects these three management on chemical physical quality parameters. For purpose, topsoil...

Leaf area index (LAI) and canopy structure are important parameters affecting grape quality yield of grapevines. Two different experimental protocols as well the average LAI value for indirect estimation by gap fraction analysis in VSP-trained grapevines (<i>Vitis vinifera</i> L. cv. Riesling) were tested this study using plant (PAI). Measurements performed a analyzer. Directly measured estimated PAI compared. Protocol SFC (sensor facing canopy) gave accurate estimates measuring along...

Organic and biodynamic management practices in viticulture have been sharply increasing worldwide for almost two decades are seen as one possibility environmentally friendly production. Consumers often presume that the quality of organically grown crops is different or higher compared to conventionally crops.In current study, wine grape under integrated, organic was assessed a long-term field trial Geisenheim, Germany, starting seven years after conversion. Treatments substantially differed...
