Validation of the enriched 15 N isotope dilution technique and the 15 N natural abundance method for studying symbiotic N 2 ®xation in permanent grassland using various
Our experiment con®rmed that during culture in agar earthworms loose all soil from their gut and may be used for chemical analysis with- out any disturbance from elements
Absolute cell numbers alone do most likely not allow a good predic- tion of CH 4 productivity for two reasons: First, the variability between dierent soil cores is too high
These subjects include earthworm systematics and biogeography, the demography of earthworm populations and communities, the role of earthworms in nutrient cycling, organic matter
Our objectives with this work were (1) to assess whether elevated [CO 2 ] aected the basic litter quality of senesced litter from an area with naturally elevated levels of
When comparing soils with dierent concentrations of weathered hydrocarbons, no assumptions were made regarding how weathered dodecane would aect min- eralization of added
We investigated and measured the role of dierent food sources on enzyme activities in the casts, as well as the rates of food consumption and cast production by the earthworms..
The study demonstrated that nitri®cation and denitri®cation occur simultaneously in compacted silty grassland soils at moisture conditions close to ®eld capacity.. All
