the aim of this study was to assess the conversion of forest to vineyard on different physical pools of organic matter in zrebar lake watershed. soil samples were collected from the two major land use types including forest and vineyard land at 0-30; 30-60, and 60-90-cm depths. in each land use, different soc fractions were measured. according to the results of size fractionation of organic car...

Wine quality depends on many factors, such as the choice of variety, stock, training system, pruning as well as environmental parameters and cultivation techniques performed in the vineyard. Monitoring the micro-climate of grapevine allows to conveniently perform the most important cultivation techniques (soil management, pesticide treatments, green pruning, harvest) thus reducing the operating...

California grape production is a multi-billion dollar business, but only a small fraction of the productive acreage is farmed organically. One aspect of organic management is the pest control strategies, which rely heavily on biological and cultural controls, as well as approved pesticides. To determine what factors might restrict adoption of organic farming practices, we describe the current s...

The grape berry moth, Paralobesia viteana Clemens (Lepidoptera: Tortricidae), is a key economic pest of vineyards in eastern North America, and prevention of fruit infestation is particularly challenging along vineyard borders that are adjacent to wooded areas containing wild grape (Vitis spp.). For three years, infestation and damage in vineyards where reduced-risk insecticides were applied to...

Many farming-system studies have investigated the design and evaluation of crop-management practices with respect to economic performance and reduction in environmental impacts. In contrast, little research has been devoted to analysing these practices in terms of matching the recurrent context-dependent demand for resources (labour in particular) with those available on the farm. This paper pr...

In viticulture, knowledge of vineyard vigour represents a useful tool for management. Over large areas, the grapevine vigour is mapped by remote sensing usually with vegetation indices like NDVI. To achieve good correlations between NDVI and other vine parameters the rows of a vineyard must be previously identified. This paper presents an unsupervised classification method for the identificatio...

Grapes for wine production are a highly climate sensitive crop and vineyard water budget is a decisive factor in quality formation. In order to conduct risk assessments for climate change effects in viticulture models are needed which can be applied to complete growing regions. We first modified an existing simplified geometric vineyard model of radiation interception and resulting water use to...

Understanding factors controlling root dynamics and functioning can lead to more efficient and profitable vineyard management. However, our current understanding of root dynamics and their regulation by plant and environmental factors is limited, particularly under field conditions. This paper presents current understanding of grape root dynamics, highlighting studies using minirhizotron camera...
