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

Carbon-13: carbon-12 ratios in dissolved and particulate organic matter in the sea
Philip M. Williams,L.I. Gordon +1 more
TL;DR: In this article, a technique was developed for the determination of the 13 C/12 C ratios in the dissolved organic matter in the sea and the results suggest a singular and common source for the dissolved and particulate organic matter and that this material is stable to biochemical fractionation.

Seasonal and long-term resource-related variations in soil microbial communities in wheat-based rotations of the Canadian prairie
Chantal Hamel,Chantal Hamel,Keith Hanson,F. Selles,Andre F. Cruz,Reynald Lemke,Brian McConkey,Robert P. Zentner +7 more
TL;DR: In this article, the authors used a 37-yr old long-term wheat-based rotation experiment located in the semiarid Brown soil zone of Saskatchewan to test the hypothesis that different rates of N and P fertilizers, and cropping frequency (modifying C input to soil) influence the size, structure and physiological condition of soil microbial populations residing in the plough layer.

TL;DR: In this paper, the authors used the quantitative biogeochemical model PnET-BGC to test assumptions about the direct and indirect effects of climate change on a northern hardwood forest ecosystem.
Journal ArticleDOI
Occurrence of salt, pH, and temperature-tolerant, phosphate-solubilizing bacteria in alkaline soils
TL;DR: The results indicated the role of calcium salt in the phosphate solubilization ability of NBRI4, and among the various bacteria tested, NBRI 4 and NBRI7 did not produced halo in a plate assay at 30°C in the absence of salt.

Chapter 3 Microbiology of the composting process
H. Insam,M. de Bertoldi +1 more
TL;DR: This chapter discusses the microbiology of the composting process, where all of the microbial transformations of nitrogen occurring in nature also take place during composting, even if with different significance.
