TLDR
In this paper, the biological processes that take place in the soil and their importance to soil fertility, plant growth, and environmental quality are investigated from both descriptive and functional viewpoints, including microbial ecology, the carbon and nitrogen cycles, mineral transformation, and ecological interrelationships.Abstract:
Characterizes soil microflora from descriptive and functional viewpoints; considers the biological processes that take place in the soil and their importance to soil fertility, plant growth, and environmental quality. Deals with the biochemical basis for soil processes, including microbial ecology, the carbon and nitrogen cycles, mineral transformation, and ecological interrelationships.read more

Journal ArticleDOI
Distantly sampled soils carry few species in common.
TL;DR: These analyses, based on the largest soil bacterial sequence retrieval to date, establish the high degree of community structure difference for randomly sampled dissimilar soils and support the idea that wide sampling is important for bioprospecting.

Comparison of microbial numbers in soils by using various culture media and temperatures
F.C.S. Vieira,E. Nahas +1 more
TL;DR: Higher numbers of total bacterial and fungal colony-forming units (CFU) were observed in sorghum soils, and of spore-forming and Gram-negative bacteria in forest soils than other soils, which were dependent on the media and incubation temperatures.

Heterotrophic nitrification among denitrifiers.
D Castignetti,T C Hollocher +1 more
TL;DR: Those denitrifiers active in the nitrification of pyruvic oxime or hydroxylamine or both are abundant in soils and possible advantage of having nitrification and denitrification capabilities in the same organism is discussed.

Atmospheric nitrous oxide
David Robert Bates,P.B. Hays +1 more
TL;DR: In this article, the information relating to atmospheric nitrous oxide is reviewed and the most probable source is microbiological as first suggested by Adel, however the slow homogeneous chemical reaction between ozone and nitrogen is not excluded by the laboratory work reported.
