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

Influence of bedrock geology and tree species composition on stream nitrate concentrations in mid-appalachian forested watersheds
TL;DR: In this article, the authors investigated the relationship between watershed geology and stream nitrate levels in 49 mid-Appalachian forested watersheds and found that watersheds dominated by Pottsville and Allegheny sandstone (PVA), Catskill, Chemung and Chemung shale and sandstone, and Mauch Chunk shale and Greenbrier limestone (MCG), respectively, exhibited significantly different low, intermediate, and high mean stream Nitrate concentrations.

Formation Mechanisms of Complex Organic Structures in Soil Habitats
TL;DR: The synthetic reactions discussed in this chapter are essential to the constant replenishment of humus, and one significant benefit is the neutralization of certain natural soil organic substances, such as benzoic acid, vanillin, and other lignin decomposition products, which have been proved to be toxic to plants.

Fumigation-extraction method to estimate microbial biomass in heated soils
TL;DR: In this paper, the fraction of the biomass rendered extractable to K2SO4 after microbial cells lysis by chloroform was used to estimate microbial biomass C and N in forest soil samples unheated or heated at 160, 350 or 600°C for 30 min, 2 or 4 hours.

Use of mulberry-soybean intercropping in salt-alkali soil impacts the diversity of the soil bacterial community.
TL;DR: The specific plant species was the major factor that determined the bacterial community in the salt–alkali soils and the diversity and composition of bacterial communities varied between monoculture and intercropping samples.

Near-surface monitoring strategies for geologic carbon dioxide storage verification
TL;DR: In this paper, the authors proposed a method to detect CO 2 leakage and seepage in the near-surface environment by using a light distancing and ranging (LIDAR) system.
