EU-based production and exploitation of alternative rubber and latex sources (EU-PEARLS) (Project)
Natural rubber is a widely used raw material essential to industry, medicine, transportation and defence, whose major source, the rubber tree Hevea brasiliensis, is currently both sustainable and environmentally beneficial. However, increased worldwide demand for natural rubber and latex means that alternative sustainable sources are urgently required. In order to meet this challenge, we propose...

Oceanography & climate: Assessment of short-term climatic variations in the Labrador Sea (Correlation of Greenland cod (Gadus morhua) recruitment data and ocean/atmosphere environmental data) (Project)
Short-term climatic variability in the area of the atmospheric north polar front leads to variation in the North Atlantic Current system on time scales of weeks to a year. As a result of these changes, ocean temperature, salinity and current variations influence local conditions for growth of Greenland cod (Gadus morhua). This project analyses correlations between climatic and recruitment...

Sequestration of carbon in soils: Mechanisms and type of fixation (Project)
Up until the eighties of last century the dynamic of soil organic matter (humus) was mainly considered under the aspect of soil fertility. In recent times this soil compartment attracted new attention as a sink and source of CO2. In regard to the increase of CO2 in the atmosphere it has been assumed that suitable agricultural practices can lead to an additional fixation of carbon in soils. The...

Assessment of the fluxes of reactive trace gases, aerosol constituents and sedimenting particles between the atmosphere and agro-ecosystems (Project)
The monitoring of fluxes of those trace gases and aerosol constituents for which automatic analyzers (with a high resolution in time using optical properties of the species considered) are not available has to make use of concentration measurements using denuders and/or filters and combine them with micrometeorological models. The FAL site is one of the very few locations in Europe with adequate...

Application of stable Carbon-, Nitrogen- and Sulphur isotopes to characterise and indicate fluxes in agricultural systems under different land use and environmental conditions (Project)
Carbon (C), nitrogen (N) and sulphur (S) naturally occur with several stable isotopes of different masses. The relative abundance of these isotopes is different and they are turned over in biological, chemical and physical processes at different rates. Hence pools of different isotopic composition develop and depending on their origin and history, C-, N- and S- containing substances differ in...

Lachgas(N2O)-emission und Kohlenvorrätestoffe landwirtschaftlicher Böden: Messungen und Inventar-Erstellung incl. Systemvergleich ökologische/konventionelle Bewirtschaftung (Project)
The extent of nitrous oxide emissions from and the changes in the soil organic carbon pools of agricultural soils have to be estimated annually depending on the different ways of agricultural land use, in order to fulfil the report duties of Germany due to the Convention on Climate Change and the ?Kyoto? protocol. All regulations regarding the establishment of inventories given hereto in the...

: Monitoring of vertical fluxes of energy, water vapour and trace gases above an arable field including improvements of the methodology applied (Project)
Within the BMBF joint project VERTIKO fluxes of energy and matter between atmosphere and biosphere are determined by measurements and models. At the FAL site, concentration monitoring is performed above arable land of NH3, HNO2, HNO3, SO2 as well as particle-NH4, -NO3 and -SO4.

In-depth review of the outputs of DEFRA`s programme of research on measurements and control of ammonia emissions from agriculture (1998-2002) (Project)
The various research projects funded by the UK Department for Environment, Food and Rural Affairs (DEFRA) to quantify agricultural ammonia emissions and their reduction potential were evaluated with respect to their quality and completeness. Weak points were named and recommendations were given with respect to future funding policy.

Soil properties, carbon and nitrogen turnover in deciduous forest soils with different tree species diversity (Project)
The influence of different deciduous tree species on 1) soil acidity, 2) nutrient recycling via leaf litter and 3) soil C and N dynamics is studied in the Hainich National Park. The project is part of the DFG Research Training Group 1086 'The role of biodiversity for biogeochemical cycles and biotic interactions in temperate deciduous forests'.
