Beyond NDVI: Grape Maturity Maps for Better Quality Wine
2-minute read To achieve the desired quality of wine, grapes need to be harvested at a specific maturity level. A key determinant of maturity is grape sugar levels. In simple terms, sugar levels at the time of harvest determine the alcohol content of the wine produced, but it goes beyond that to affect the characteristics and temperament of the wine. Predicting when grapes reach the desired ...

Grape Maturity Predictions Made Easy with AI
Grape maturity monitoring is an important task as it is used to make one of the most critical decisions during the growing season - determining when grapes are likely to be ready for harvest. Currently, chemical indicators such as sugar levels, acid content, and pH are used along with qualitative measures (e.g. skin tannins, aroma, and flavour) to monitor grape maturity. As grapes mature, ...

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 ...

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 ...

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 ...
