Abundant colonization of VAM fungi was found in all 15 plants analyzed from the native soil treatment, and chlamydospores produced by Glomus spp.

|
These results are discussed in relation to the ecological influence of AM inoculation, with selected fungal strains and their associated microflora on native soil microbial activity.
|
| |
|
They were more marked on native soil than on sterile one.
|
| |
|
The plants were grown in their native soil under ambient and elevated atmospheric CO2 content (pCO2) at the Swiss FACE (Free Air CO2 Enrichment) facility.
|
| |
|
californica performance was significantly reduced when grown in invaded soil compared to native soil (flowering date was delayed, aboveground biomass decreased, specific root length increased, and root mass ratio increased).
|
| |
|
triuncialis performance were unaffected when grown in invaded vs native soil.
|
| |
|
Relatively greater SOC was often observed in poplar when native soil carbon was low, but there were important exceptions.
|
| |
|
Plasmid transfer from the introduced GEM to members of the native soil flora was observed in situ.

|
In this study, we used a common substrate to study the effects of native soil P availability as well as artificially elevated P availability on litter decomposition rates in a lowland Amazonian rain forest on highly weathered soils.
|
| |
|
Native soil organic matter (SOM) decomposition of the DRS was lower than the SOM decomposition of the IRS.
|
| |
|
No evidence was found that under elevated CO2 substantial amounts of N had been immobilized by the SMB, nor that mineralization of native soil organic matter (SOM) had been stimulated by an increased supply of substrate to the SMB.

|
Native soil Ca level without amendment (550 mg Ca/kg soil) was sufficient for potato plant growth under normal temperatures.
|
| |
|
Additionally, rhizosphere microbial communities in newly invaded areas are more similar to the original native soil communities than are microbial communities in areas that have been invaded for several years.
|

|
In native soil, however, the rate of metolachlor disappearance was not enhanced by Streptomyces inoculation.
|
| |
|
In inoculated sterile soil the yields of products were affected by inoculum size, inoculation temperature and substrate concentration, but these variables had no effect on product formation in the inoculated native soil.
|
| |
|
Addition of Na2CO3 (200 μg/g soil) into native soil significantly promoted growth of Streptomyces due to the higher pH (7.8) and also stimulated transformation of metolachlor by 30%.
|
| |
|
Our results suggest that proliferation of the inoculated organisms under favorable conditions is essential for their function as metolachlor degraders in native soil.

|
Native soil cores containing a ceramic suction cupwere installed in the field, roofed and watered every two weeks withlocal throughfall or local throughfall with added(NH4)2SO4 at 75 kgNH4+-N ha-1 a-1.
|

|
Buried mineral soil-bag changes over time reflected both the native soil environment and the treatments.
|
| |
|
The assumption that a genotype is better adapted to the `native' soil from which it was collected than to other soils, was tested.
