Objectives: This study was carried out for assessing total and available soil Cu in a Carixien soil series of a part of Burgundy, France. Method: Soil samples were collected from surface-ploughed layer in agricultural fields across the southern part of the Yonne district, Burgundy, France. The extraction time of soil Cu ranged from 5 minutes to 24 hours. Findings: The result on Carixien soil was Chaponne. And the trend of extraction on the Carixien soil was different from the results on Domerien soil. The pH value of the extracted solution increased for the Chaponne soil. For purpose of comparison it remained steady in the case of the Dubloc soil from the Domerien soil series, the copper (Cu) absorbance through the atomic absorption spectrophotometry and its content. The Cu concentration in the extracted solution increased up to the 24h-extraction (+ around 200 %) on the basis of 5 minutes. In the case of the Dubloc soil from the Domerien soil series, the Cu concentration in the soil extract only slightly increased during the 24h-extraction period (+ around 100%) on the basis of 5 minutes. Novelty: From these data it is considered that while Domerien soils have no 'hole' for Cu extraction, Chaponne soil has a 'hole' for Cu extraction.< Leer menos
