native soil
The sorption processes of uranium(VI), copper, cobalt, and strontium by the native soil were studied.
      
The chemical nature of nitrogen in native soil organic matter
      
Competition from native soil rhizobia is likely to be an important factor limiting Phaseolus vulgaris L.
      
Supercritical fluid extraction of polycyclic aromatic hydrocarbons (PAH) from native soil and fly ash with pure and modified
      
Finally, the micro-column fractionation was used for the determination of non-ortho substituted PCBs in native soil samples.
      
These results were indicative of more aromatic ring polycondensation and humification of soil HAs, and of partial incorporation of simple and low-humified components of MSWC-HA into native soil HA, as a result of MSWC amendment.
      
Mn peroxidase was found to be a highly stable enzyme that remained active for several weeks under reaction conditions in a liquid reaction mixture and even persisted in sterile and native soil from an opencast mining area for some days.
      
Effect of cooperation between native soil microorganisms and white-rot fungus Bjerkandera adusta R59 on degradation of daunomycin post-production wastes in soil was described.
      
This effect was conjugated with the propagation of native soil microorganisms (microfungi and bacteria) more significant than in parallel system without R59 strain.
      
Recovery in hydrolysable forms was much greater for the fixed N than for the native soil N, indicating that the former was more available for uptake by plants.
      
The evolution of gaseous N from native soil N is not taken into account by this procedure.
      
The method allows a quantitative estimate of the relative contributions to the emitted gas by both the original enriched source and the native soil N.
      
These results suggest that organic-matter-fixed liquid anhydrous NH3 is initially more labile than the native soil N but becomes less labile with time.
      
Fate and interaction with native soil N of ammonium N applied to wetland rice (Oryza sativa L.) grown under saline and non-salin
      
The effect of salts on the balance of fertilizer N applied as 15N-labelled ammonium sulphate and its interaction with native soil N was studied in a pot experiment using rice (Oryza sativa L.) as a test crop.
      
The objectives were: (1) to compare the immobilization and interaction of NHinf4sup+-N and NOinf3sup--N with the native soil N, and (2) to study the relationship between immobilization of applied N and the added N interaction.
      
A question that still remains after countless experiments is the use of an appropriate nonfumigated control for accounting for native soil organic matter (SOM) mineralization during incubation.
      
Changes in the native soil pH also affected the CH4-oxidizing capacity.
      
The positive effect of Baythroid was attributed to: (1) a prolonged availability of NHinf4sup+due to inhibition of nitrification, (2) an increased availability of native soil N through enhanced mineralization, and (3) an enhanced root proliferation.
      
A laboratory incubation experiment showed that the availability (percentage mineralization) of recently immobilized 15N was greater than that of native soil 14N.
