Element availabilities on agricultural areas - analysis and evaluation
Project
Project code: JKI-ÖPV-08-1367
Contract period: 01.01.2016
- 31.12.2018
Purpose of research: Applied research
Analysis and evaluation of different element availabilities and sequestration processes depending on different soil properties of agricultural areas. Heavy metals are introduced targeted into agricultural soils as plant nutrients (e.g. Fe, Mn, Mo, Cu, Zn) or pesticides (e.g. Cu, Fe, Zn) and non-targeted introduced due to atmospheric deposition or contamination of fertilizers. Possible toxic effects of heavy metals in soils are not only depending on total element concentrations but also on the type of binding and thus bio availability of the respective element for plants and organisms. The bio availability of elements in the soil for flora and fauna varies widely and is influenced by site-specific physical-chemical soil parameters. To get a comprehensive overview of the sequestration potential of relevant elements (e.g. As, Cd, Cr, Cu, Pb, Ni, Zn) in agriculture soils the total and mobile (bio available) element contents are determined continuously in project related soil analysis using the sequential extraction method. This research allows the estimation of potential risks for various plants and organisms that emanate from heavy metals in different soil types and land uses.
