The ability to track vortices spatially and temporally is of great interest for the study of complex and turbulent flows. A methodology to solve the problem of vortex tracking by the application of machine learning approaches is investigated. First a

The response of terrestrial ecosystems to elevated atmospheric CO 2 is related to the availability of other nutrients and in particular to nitrogen (N). Here we present results on soil N transformation dynamics from a N-limited temperate grassland th

Application of organic carbon to grassland in the form of manure or cattle slurry during the growing season is a normal agricultural practice. Under enhanced organic C supply changes in the grassland soil's internal N cycling and in the microbial com

The contribution of bacteria and fungi to NH 4 + and organic N (N org ) oxidation was determined in a grassland soil (pH 6.3) by using the general bacterial inhibitor streptomycin or the fungal inhibitor cycloheximide in a laboratory incubation study

The most widely used method to quantify gross N transformation rates in soils is based on 15 N dilution and enrichment principles. To identify rate parameters, 15 N-tracing experiments are analysed by models that are linked to algorithms that try to

The objective of this study was to separate the observed nitrite (NO; ) concentration in a permanent grassland soil into process-specific subpools. A laboratory experiment was carried out where either the nitrate and/or ammonium pool was labelled wit

Much work has been done on gaseous emissions and leaching of nitrogenous compounds from whole soil profiles and also from soil surface measurements which are assumed to be mainly due to topsoil activity. In soils with an impervious clay subsoil, the
