EVI vs NDVI: What’s the difference?
The wine industry has been using aerial imaging to measure vine vigor for decades. It is becoming more and more common for vineyard managers to use vigor maps to support their decision making in the field. These maps most often use the Normalized Difference Vegetation Index (NDVI) to measure vine vigor. NDVI has been the standard in the wine industry since the Mondavi Project in 1992. NDVI is a ...

Ohh Hengelo Ohh Hengelo...
What’s better than installing one Rocket Composter? Only the obvious…. More! Our colleagues and friends in the Netherlands, specifically the municipality of Hengelo asked Tidy Planet to provide their composting equipment for the purposes of proving the feasibility of providing separate household food waste collections. The food wastes would be brought back to the enormous city farm, ...

Grapes Dehydration for Raisins Production in Turkey
Raisins are produced commercially by drying harvested grape berries. In order for a grape berry to dry, water inside the grape must be removed completely from the interior of the cells onto the surface of the grape where the water droplets can evaporate. However, this diffusion process is very difficult because the grape skin contains wax in its cuticle, which prevents the water from passing ...

Sachets ETHYL STOPPER, green alternative to SO2 use in organic grapes
The grape is a non-climacteric fruit which is highly sensitive to fungal infections, especially Botrytis cinerea. The most common treatment currently available to prevent these infections and maintain fruit quality is to fumigate with SO2 and use metabisulphite. Whilst these treatments are effective, they present a number of inconveniences: Development of stains and decolouring of fruit. ...

Arsenic present in the soil‐vine‐wine chain in vineyards situated in an old mining area in Trentino, Italy
The present study follows arsenic (As) transfer through the chain of soil‐vine‐leaves‐grapes‐wine to assess the possible risk of arsenic intake related to consuming grapes and wines produced in 10 vineyards located in a mining area rich in this element. The results are compared with date from 18 uncontaminated areas. In the soil, the content of As extracted with acqua regia and that available, ...

Nondestructive measurement of grapevine leaf area by ground normalized difference vegetation index
Vine leaf area index has a great impact on berry quality. This study was conducted to determine whether vine leaf area index could be estimated, and mapped through normalized difference vegetation index (NDVI) ground-based measurements. The NDVI measurements were performed using a Greenseeker (N-Tech Industires, Ukiah, CA and Oklahoma State Univ., Stillwater), pointed sideways at the vertical ...

Trace element and heavy metal concentrations in fruits and vegetables of the Gediz River region
The Gediz river that irrigates the largest agricultural part of the Aegean Region's "Gediz Plain" is being polluted by industrial and domestic wastes starting from the Murat Mountain and continuing to the river's mouth. To study the pollution status, vegetables (tomato, pepper, bean, purslane, cowpea), fruits (apple, plum, pomegranate, walnut, watermelon, peach, cherry, grape), and leaf samples ...

The role of soil chemistry in wine grape quality and sustainable soil management in vineyards
ABSTRACTThis study aimed to establish if there is any evidence that soil mineralogical and/or chemical composition influence the composition and quality of wine grapes. In the initial phase of the study, soils and grapes were sampled in two riesling vineyards in South Australia. Soils were analysed for a wide range of total major and trace elements; soil cation extracts and grape juices were ...

Waste stream utilisation for sustainable viticulture
ABSTRACTField trials were established at four vineyards in January 1999 to evaluate the effects of four mulch mixtures on different soil and plant parameters. Mulches were made from wine industry and other commercially available plant and animal wastes. Soil, grape petioles, grape leaves and grape juice were analysed over three seasons. The mulches applied released considerable quantities of ...
