Improvement of disease resistance of potato (Project)
New sources of resistance originating from wild Solanum spp. (S. tarnii, S. bulbocastanum, S. cardiophyllum, S. pinnatisectum) against most important potato viruses (Potato virus Y and Potato leafroll virus), and if possible against Phytophtora, will be utilised for resistance breeding. Introduction will be performed by protoplast fusion and successive back-crossing steps.

SFB/TRR 32 Project B1 Phase 1: Characterizing spatio-temporal patterns of water and C-fluxes at field-scale (Project)
The main goal of this project section is to identify and relate spatial and temporal structures of soil state variables like water content and soil temperature to carbon dioxide exchange fluxes and evapotranspiration fluxes in the soil-plant-atmosphere system at field scale. We aim at quantifying the sinks and sources of water and carbon dioxide at the soil-plant-atmosphere interface from...

SFB/TRR 32 Project A2 Phase 1: Characterization of flow and transport properties of unsaturated soils using non-invasive methods and numerical modelling at the µm to dm scale (Project)
Structure and state of soils have considerable influence on their flow and transport properties in particular for the vadose zone. We will develop an interpretation scheme for combined measurements of spectral induced polarization (SIP) and nuclear magnetic resonance (NMR) in order to assess structure, state, and thus flow properties of partially saturated soils. The relations between the...

Determination of di-iso-butylphthalate (DiBP) and di-n-butylphthalate (DnBP) in paper and board packagings for infant formulae and in the packaged food (Project)
New findings show a high transfer of DiBP into foodstuffs from paper and board packagings containing recycled fibres (up to 5 mg DiBP/kg). Its use in dispersion glues used in paper packagings and products not intended for use in food contact applications is deemed to be the source for the presence of DiBP. When recycled DiBP is released from this material into the paper cycle and thus can be...

SFB/TRR 32 Project A1 Phase 1: Pore structure, moisture, and water transport in soil by NMR (Project)
This project section characterizes pore structure, wetting properties, and directional unsaturated water fluxes for soil samples by nuclear magnetic resonance (NMR) imaging of moisture and gas in voids, and by relaxation, diffusion and flow studies under partial wetting conditions. Laboratory studies will be followed by field studies with the mobile “NMR spade” to be developed for measuring...

Investigation on the skin penetration and skin toxicity of polycyclic aromatic hydrocarbons (Project)
Polycyclic aromatic hydrocarbons (PAH) are genotoxic carcinogens which are detectable in numerous consumer products, as for example hammer grips or cable sheets. Sources of PAHs are softener oils, carbon blacks and so forth. Although some of these chemicals had long been recognised as potent carcinogens in skin carcinogenesis assays in mice, very little is known about organ-specific toxicity or...

SFB/TRR 32 Project B3 : Spatial and temporal patterns of soil carbon pools - a MIR-spectroscopic approach (Project)
The specific environmental conditions adjacent to potentially mineralizable organic matter control the CO2 production in soil. This study aims at identifying spatio-temporal patterns of different soil carbon pools from field scale (m2 to ha) to regional scale (km2) and to relate them to patterns of soil parameters (clay, iron oxide, etc.), to soil microclimate, and to CO2 evolution. For the...

SFB/TRR 32 Project B4 : Upscaling of local C02, water and heat fluxes to the field scale from observed spatio-temporal patterns using an integrative 3-D mechanistic process model (Project)
A 3-D process model, which simulates spatio-temporal distributions of water, energy and CO2 fluxes, turn-over of soil carbon pools, plant water uptake, transpiration, assimilation, and respiration within a field plot, will be developed. The model will be used to interpret spatial patterns and their interdependencies of soil properties (hydraulic properties and carbon content), state variables,...

SFB/TRR 32 Project C1 : Spatio-temporal variability of catchment properties and their effect on water, solute, and CO2 fluxes from the micro to the mesoscale (Project)
We develop methods for a scale dependent treatment of patterns in properties and boundary conditions when simulating water, CO2 and solute transport of micro- to mesoscale catchments. Geostatistical methods are used to parameterize patterns derived from measurements. Rules will be derived for the scale dependent characterisation of patterns using a 3d simulation model. The statistical analysis of...

SFB/TRR 32 Project C4 : Scale–consistent two-way coupling of land-surface and atmospheric models (Project)
We will build a fully coupled model system which comprehensively simulates atmosphere, vegetation and soil including their exchange processes related to water, CO2, heat and momentum. Processes within the sub-systems will be resolved on their respective intrinsic temporal and spatial scales while the two-way coupling between the sub-systems will contain appropriate up- and downscaling schemes....
