THE RELATION BETWEEN THE CARBON AND NITROGEN BIOGEOCHEMICAL CYCLE IN ANTHROPOGENIC ECOSYSTEMS AND ITS IMPORTANCE FOR THE ENVIRONMENT

Ziel

STUDY OF THE NITROGEN AND CARBON CYCLES.

INTEGRATION OF KNOWLEDGE BY MODEL DEVELOPMENT

THERE EXIST NUMEROUS DATA SETS AND CONCEPTS ON THE PROCESSES WHICH TOGETHER DESCRIBE THE ROLE OF CARBON AND NITROGEN IN THE BIOCHEMICAL CYCLE (E.G. BUILD UP, SOIL ORGANIC COMPOUNDS, NITRIFICATION, DENITRIFICATION, LOSSES TO ENVIRONMENT BY VOLATILISATION, LEACHING, REMOVAL OF CROP). THE ONLY WAY TO INTEGRATE THIS KNOWLEDGE IS BY MODEL DEVELOPMENT. THE CONSTRUCTION OF HIERARCHIC MODELS IS FORESEEN, EXPERIMENTS ARE, HOWEVER, ORIENTED ON A SUBMODEL FOR SOIL MICROBIOLOGICALLY MEDIATED BUILD UP AND DECOMPOSITION OF SOIL ORGANIC COMPOUNDS.

THE EXPERIMENTS INCLUDE:

DETERMINATION OF MICROBIOLOGICAL SOIL BIOMASS. DETERMINATION OF THE ACTIVITY OF ROOTS AS A CARBON SOURCE FOR SOIL MICROORGANISMS. (USE OF PHYTOTRON AND 14CO2). DETERMINATION OF ROOT EXUDATES AS CARBON SOURCE FOR MICROORGANISMS. DETERMINATION OF PROTONFLUX FROM PLANT ROOTS, INDUCED CHANGES OF RHIZOPHERE. DENITRIFICATION (ACETYLENE INHIBITION AND 14N).
