Publisher Summary This chapter highlights the physiology of autotrophic ammonia-and
nitrite-oxidizing bacteria. Several aspects of the physiology of nitrifiers of relevance to their …

Nitrification in acid soils was first reported in the beginning of the 20th century. Although this
finding has been well substantiated by countless studies since then, it has until recently …

Studies of nutrient cycling in forests span more than 100 yr. In earlier years, most attention
was given to the measurement of the pools of nutrients in plants and soil and of the return of …

Emission Of NOx (principally NO) and N2O from soils is reviewed with particular emphasis
placed on the atmospheric and ecological implications of this source. The photochemistry of …

Net nitrification in forest soils is potentially problematic as it can promote nitrogen and cation
losses as well as soil acidification and favor competing vegetation in regenerating forests …

Heterotrophic nitrification is regarded as an eternal mystery in the nitrogen (N) cycle,
although it was first reported more than 100 years ago. In this review, we discuss microbial …

Methane consumption by forest soil was studied in situ and in vitro with respect to responses
to nitrogen additions at atmospheric and elevated methane concentrations. Methane …

By synthesizing more than twenty years of research at the Fernow Experimental Forest, we
have documented 7 symptoms of nitrogen saturation in two adjacent watersheds. The …
