Evaluation and Mapping Spatial Distribution of Copper Pollution in Soil and Water of Vineyard Garden

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.


In this study, soil and water chemical parameters including copper contamination, pH and EC as well as soil organic matter and texture were determined in 23 stations across Malayer vineyards in a completely randomized layout. 


The soil texture of vineyards was a type of sandy loam in the study area which is suitable for grape seedlings growth.Copper concentration ​​was significantly higher than the level required for optimum grapevine growth but less than the contamination level. The water and soil pH and soil organic matter content were in optimum condition. While soil EC was in normal range according to the Ministry of Agriculture standard, the EC value of water was above the optimum value, which can be due to the unauthorized deep-water wells and exposure to the saline watertable.


According to the results, it seems that the sharp increase in copper concentration in the Malayer vineyard could be a result of fungicides application as well as pollution transmittal of mining, factories and chemical and animal fertilizers application in the study area.
