Collaborative project: Optimization and practical testing of an assistance system for crop protection - subproject C (Project)
Within the project "Assistance system for site specific application of pesticides" an overall system was developed, in which site specific application maps for sustainable and resource-saving crop protection are planned, generated and documented by using automated integration of various web services. This assistance system, consisting of the web GIS application "AssSys - WebPortal" as an...

SFB 564: B4.2 - Towards sustainability of land use in a highly vulnerable and degraded tropical soil landscape of northern Vietnam – bridging scales (Vietnam component) (Project)
As the majority of people in the northwest of Vietnam depend on agriculture, reduced yields as a consequence of soil degradation are a serious threat. B4.2 aims to analyze the suitability for agricultural use and the vulnerability of the soils in the whole Yen Chau district. In order to establish a regionalization of meaningful parameters which affect crop growth, a SOTER database covering the...

SPP 1315: Quantification of active interfaces with respect to dissolved chemicals in unsaturated structured soil (Project)
The main goal is to develop a new methodological approach to quantify the effect of soil structure on fluid dynamics and interaction of dissolved chemicals in natural soil at the scale of a soil horizon. The conceptual perspective is that of a particle and what it 'sees' on its way through soil. The approach is based on high resolution X-ray tomography of natural structured soil samples with a...

SPP 1315: Role of biocolloids for the formation, dynamics and maturing of biogeochemical interfaces (Project)
Relocation of organic matter (OM) in soil including biocolloids such as fungi and bacteria is a decisive process for the formation and depth propagation of biogeochemical interfaces. We assume that during the transport in soil mobile OM (I) accumulates under no-flow conditions, (II) is mobilised upon onset of flow and is (III) preferentially retarded at materials with high surface area and...

SPP 1315: Hydration affected soil: water sorption processes of xenobiotics - experiments and modeling approaches (Project)
The sorption of xenobiotics in soil is governed by the physicochemical properties of the sorbate. Likewise sorption depends on the properties of soil organic matter (SOM) as the main sorbent in soil. SOM has a high molecular variability resulting in an amorphous structure and different structural domains. SOM is strongly influenced by environmental factors; hydration status and salts can either...

SPP 1315: Partitioning of organic chemicals into soil micro-sites - Analyses of their fate and interactions with the resident microbial communities (Project)
The objective of this project is to follow the distribution and degradation of selected organic pollutants in the different micro-sites (mineral particle size classes) in soil and to characterize the structural diversity of the microbial communities present, exposed and potentially participating in the degradation processes of the pollutants.

SPP 1315: Detection and imaging of selected organic chemicals on soil interfaces in the millimeter- to micrometer-range by micro GC/LC- and DESI mass spectrometry (Project)
Analytical experiments with high spatial and temporal resolution at the mm to µm range with new methods in mass spectrometry will be conducted. Six chemicals covering a wide variety of physical and chemical properties will be selected and their binding and fate should be studied by GC-MS and LC-MS. In addition, desorption electrospray ionization mass spectrometry (DESI-MS), a recently introduced...

SPP 1315: Bioavailability of hexadecane during the degradation of litter from C3 and C4 plants in different soil compartments and its influence on the induction of alkane degrading genes from prokaryotes (Project)
Aims: Understanding gene expression and stability of enzymes in soil microhabitats Hyptheses: H1: During degradation of maize and rapeseed litter, hexadecane is released into the surrounding soil. H2: A gradient of hexadecane will arise as a function of the distance to the litter surface, with the highest concentrations close to the emitter. H3: Microbial communities will express genes involved...
