Analysis of soil solutions from several forest and heathland communities indicated that ammonium ions were more preva- lent than nitrate ions and that soluble forms of organic
Compared to unplanted soils, the release of carbon by plant roots chan- ged the utilisation of 14 C-glucose by soil microorganisms.. The greater mineralisation of the substrate
The number of PAHs degraders, estimated by a modi®ed MPN procedure, was not signi®cantly different in the freshly spiked rhizospheric and non-rhizospheric soils, but was
We found that horizontal spatial variation in potential nitrate production, leaching of nitrate and nitrogen concentrations from non-pooled ®eld samples was higher than variation
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
The mineral soil may contribute substantially to the leaching of nitrate, since the net production of mineral N and net nitri®cation were in general higher and denitri®cation
The frequency of denitrifying, DNRA and nitrifying strains was expected to be higher in the fertilized forest soils compared with a control soil receiving no nitrogen fertilizer..
We used extended laboratory incubation and acid hydrolysis to analytically determine SOC pool sizes and ¯uxes in US Corn Belt soils derived from both forest and prairie
