The impact of plant identity and interspecific interactions on the soil microbiome in intensively managaged grasslands. ABSTRACT Plants and soil microbes are intricately linked, and agricultural production relies heavily on microbially mediated ecosystem services. However, the effects of plant diversity (richness, relative abundance and composition) on

This study reveals how soil pH regulates microbial N allocation in forest soils across Japan. We show that microbial abundance controls the overall rate of N cycling, while microbial composition and metabolic potential determine whether ammonium is released or retained.

Urine is a major waste product of human metabolism and contains essential macro- and micronutrients to produce edible microorganisms and crops. Its biological conversion into a stable form can be obtained through urea hydrolysis, subsequent nitrification,

ABSTRACT After the Dust Bowl in the 1930s, it was common to reseed native grasses in areas impacted by the drought to help restore grassland ecosystem structure and function. Given the forecasts of intensified drought events, reseeding may need to be employed more frequently to enhance post‐drought recovery. For such reseeding efforts, it is imperative

Enrichment of Comammox and Nitrite-Oxidizing Nitrospira From Acidic Soils
In agricultural soils fertilized with a high amount of ammonium nitrogen, the pH decreases because of the oxidation of ammonia by nitrifiers. Molecular-based analyses have revealed that members of the genus Nitrospira dominate over other nitrifiers in ...

Abstract Heterotrophic nitrifiers are bacteria that aerobically oxidize ammonia in the presence of organic carbon sources, which differs from autotrophic nitrifiers that extract energy from ammonia oxidation for cell metabolism and growth. The physiological significance of heterotrophic ammonia oxidation remains unclear, even though this process has ...

The responses of complete ammonia oxidization (comammox) to compound drought and heat and their contributions to post-drought nitrous oxide (N2O) emissions remain unclear.

The urea to ammonium concentration ratio is a good predictor of the relative importance of urea and ammonium to nitrite and N2O production in the ocean. In addition, the urea to ammonium ratio may be a key factor in shaping the genetic capability of marine ammonia‐oxidising archaea for urea utilisation.

Microbial Nitrogen Metabolism in Chloraminated Drinking Water Reservoirs
Ammonia availability due to chloramination can promote the growth of nitrifying organisms, which can deplete chloramine residuals and result in operational problems for drinking water utilities.

Abstract Forest disturbance increases soil nitrification rates in temperate ecosystems, but little is understood regarding contributions of newly discovered complete ammonia-oxidizing bacteria (i.e., comammox) to this important ecosystem process. We sampled soils across eight historically disturbed and adjacent reference forested watersheds at the ...
