Influence of organic amendments on copper distribution among particle-size and density fractions in Champagne vineyard soils.
The intensive use for over 100 years of copper sulfate (Bordeaux mixture) to fight against mildew in vineyard soils has led to an important, widespread accumulation of Cu (100 to 1500 mg Cu kg-1 soil). In Champagne vineyards, organic amendments are used currently to increase soil fertility and to limit soil erosion. Organic amendments may have a direct effect on the retention of Cu in the soil....
متن کاملEvaluation and Mapping Spatial Distribution of Copper Pollution in Soil and Water of Vineyard Garden
Background and objectives: The use of copper based fungicides is a crucial part of agricultural operations in vineyards, increasing productivity and crops. However, the long term application of fungicide could increase the copper concentration in the vineyard soils. Methods: In this study, soil and water chemical parameters including copper contamination, pH and EC as well as soil organic ...
متن کاملMetal availability and uptake by sorghum plants grown in soils amended with sludge from different treatments.
Several factors depending on the sludge, the soil, or the combination of both substrates, may affect element availability to plants. In this study, an assessment was done of the effect of two sludges obtained by different processes (activated sludge and facultative stabilization pond) on heavy-metal availability and uptake by sorghum plants in soils with high and low copper contents. Results ob...
متن کاملDistribution of zinc and copper chemical forms and their relationship with some physico-chemical properties and clay minerals in some calcareous soils
Determination and recognition of relative distribution of chemical forms of each element and their relationship with physical, chemical and soil clay minerals can help researchers to manage soil fertility better. This research attempted to recognize chemical fractions of zinc (Zn) and copper (Cu) in some surface and subsurface soil samples of Kohgiluyeh and Boyer-Ahmad province and their relati...
متن کاملAccumulation and distribution of metals in Phragmites australis (common reed) and Scirpus maritimus (alkali bulrush) in contaminated soils of Lia industrial area
The concentration of three metals, zinc, copper and chromium in roots, rhizomes, stems and leaves of Phragmites australis (common reed) and Scirpus maritimus, and in the corresponding sediment and water samples from Lia industrial area (Qazvin, Iran) were investigated to determine difference in distribution among plant organs. Data were collected at during 1-year period. Results showed that met...
