Copper availability on special agricultural cultivated areas - Analysis and Evaluation
Project
Project code: JKI-ÖPV-08-0095
Contract period: 01.07.2013
- 31.12.2020
Purpose of research: Applied research
Prior to regulatory decisions data concerning causes and consequences of copper fixation by chemical ageing processes at long-time specially farmed cropland have to be provided to the regulatory authorities. Hence, scientific investigations need to focus on the question why in soils with relatively high copper content only a small fraction of this element is bioavailable and in which chemical compounds copper appears in such permanently farmed cropland.
Previous to regulatory decisions data on the causes and effects of copper needs to be provided to the regulatory authorities. These data were determined considering chemical aging processes on special crop areas which have been cultivated for many years. On the basis of previously performed field studies of earthworm coenosis on 24 vine farms it was tested with simple regression approaches, whether leaching - aging factor can be derived by linking protection goal-related copper availability with the impact on biological parameters. This correction factor predictable environmental concentrations (PECsoil) resp. PNECs can be calculated in ecological and / or conventionally managed soils. With the sampling size of this study (n = 78), this factor can be assessed for the time being and be used to realistically reflect the copper availability in quality viticulture.
