Research projects running under the Federal Government's Programme "Research for the Environment" - Sub-area: "Future-oriented forestry"

1st theme
The effects of silvicultural measures on the mycorrhization of beech and pine, and analysis of the element levels in mycorrhizal fungi by means of ESEM-EDX

Partners
Prof. Dr. R.F. Hüttl, Dr. O. Bens, Dr. B.-U. Schneider (Brandenburg Technical University of Cottbus, Chair of Soil Protection and Land Reclamation)

Content
In pure and mixed stands of pine and beech, the mycorrhizal fungi were morpho-anatomically characterised and studied for their element levels by means of the radiological micro-analysis using a ESEM scanning electron microscope.

Sponsored by: Federal Ministry of Education and Research (BMBF 339754)

2nd theme
Determining the eco-system potentials of, and the limits to the conversion of pure pine stands by advance-planting of beech and oak in the North-German Lowland

Partner
Dr. R. Kätzel, Dr. R. Kallweit (Federal-state Forestry Institute of Eberswalde, Sector of Forest Evolution and Monitoring)

Content
Studies were conducted in an adult Scots pine stand along a thinning gradient, on the microbial activity and the gas exchange of the forest soil, as well as on transpiration, leaf area index and the phyllosphere microbiology of the tree stand.

Projects of research on the interaction between structure and function of communities of organisms in soils used for agriculture and forestry

1st theme
Structure and function of bacterial and fungal cellulose-degrading communities in arable soils of varying organic matter supply

Partner
Prof. Dr. Borris (Humboldt University of Berlin, Institute of Biology, Bacterial Genetics Department)

Content
The interaction between the composition of bacterial and fungal communities and their functional performance, in terms of cellulose degradation, is to be analysed in arable soils of varying organic matter supply. Two long-term field trials (Berlin-Dahlem, Bad Lauchstädt) are under study, using differentiated farmyard manure treatments and a control.

2nd theme
Soil microbial diversity and activities of an acid brown earth under pine after partial thinning for stand regeneration

Partner
Dr. H. Fritze (Finnish Forest Research Institute (FFRI), Vantaa, Helsinki, Finland)

Content
In the frame of a forest conversion approach, a pure pine stand located in the North-east German lowland is studied for possible effects of thinning on the structure, the biomass and the activity of microbial communities in soil.

Sponsored by: German Research Foundation (DFG WI 1798/4-1)

3rd theme
Structure, distribution and function of communities of soil organisms for the improvement of soil quality and nutrient utilisation in agricultural landscapes of North-East Germany and Canada

Partner
Dr. C.A. Fox (Agriculture and Agri-Food Canada, Greenhouse and Processing Crops Research Centre (GPCRC)
Dr. Y. Dalphe (Agriculture and Agri-Food Canada, Eastern Cereal and Oilseed Research Centre (ECORC))

Content
The influence is studied of various management practices on the composition, distribution and functional performance of comunities of soil organisms in sandy soils of North-East Germany and Southern Canada.

Sponsored by: Federal Ministry of Consumer Protection, Food and Agriculture (BMVEL 13/95)


Research projects regarding the C/N dynamics in different ecosystems

1st theme
Nitrogen in the phyllosphere

Partner
PD Dr. B. Stadler (University of Bayreuth (BITÖK), Animal Ecology Department)

Content
In various forest ecosystems, the interactions between phyllosphere microorganisms and leaf-sucking insects and, in particular, the resulting nitrogen flows in stand deposit are studied.

Sponsored by: Federal Ministry of Education and Research (BMBF 033 9476D)

2nd theme
Influence of reflooding degraded peatland sites of the Peene valley on the dynamics of the C-transformation processes and the emission of greenhouse gases (CO₂, N₂O, CH₄)

Partner
Dr. B. Chojnicki (Agricultural University Poznan, Polen)
Dr. J. Gelbrecht (Leibniz Association Instituty of Hydrological Ecology and Freshwater Fisheries)

Content
In the frame of combined field and laboratory studies using gas exchange measurements (hood methods, micro-meteorological techniques) and isotope techniques, the short- and long-term effects are to be studied of the reflooding of peatlands on the kind and intensity of C-transformations, C-sequestration and climate impact
