The changes in microbial biomass C and N in long-term field experiments

Plant, Soil and Environment, 2008
Microbial biomass nitrogen and carbon were studied in long-term field experiments with continuous cultivation of silage maize and with crop rotation. A positive effect of organic fertilizers on the microbial biomass nitrogen and the carbon content in ...

Soil Microbial Community Driven by Soil Moisture and Nitrogen in Milk Vetch (Astragalus sinicus L.)–Rapeseed (Brassica napus L.) Intercropping

Agriculture, 2022
The soil microbial community is not only driven by plant composition but is also disturbed by the soil environment. Intercropping affects the soil microenvironment through plant interaction, but the understanding of the relationship between soil ...

Short-term application of chicken manure under different nitrogen rates alters structure and co-occurrence pattern but not diversity of soil microbial community in wheat field

Frontiers in Microbiology, 2022
Manure application is an effective way to improve the utilization efficiency of organic resources and alleviate the adverse effects of long-term application of chemical fertilizers. However, the impact of applying manure under different nitrogen rates on

Phylogenetic analysis of microbial communities in different regions of the gastrointestinal tract in Panaque nigrolineatus, a wood-eating fish

, 2012
The Neotropical detritivorous catfish Panaque nigrolineatus imbibes large quantities of wood as part of its diet. Due to the interest in cellulose, hemi-cellulose and lignin degradation pathways, this organism provides an interesting model system for the

The influence of organic and mineral nitrogen fertilizers on microbial biomass nitrogen and extractable organic nitrogen in long-term experiments with maize

Plant, Soil and Environment, 2003
Microbial biomass nitrogen and extractable organic nitrogen in extractions by 0.05M K2SO4 and 0.01M CaCl2 were studied in a long-term experiment with successive growing of silage maize.

The Effect of Soil Microbial Residues-Mediated Nitrogen Conservation and Supply during the Growing Season on Nitrogen Uptake by Wheat

Agronomy
Microbial residue nitrogen can indicate soil quality and is crucial for soil nitrogen retention and supply. However, it is still unclear how the dynamic changes in soil microbial residue nitrogen affect crop nitrogen uptake in agricultural practice ...

Nitrogenous compounds balance and microbial protein synthesis in steers supplemented with sunflower crushed in partial replacement of soybean meal - doi: 10.4025/actascianimsci.v35i3.18654

Acta Scientiarum: Animal Sciences, 2013
Four steers in individual paddocks with Marandu grass (B. Brizantha) in 4x4 square design were used to evaluate sunflower crushed supplementation in pasture-grazing animals on nitrogen balance and microbial protein synthesis. Supplements at 6 g kg-1 body

Nitrogen addition has negative effects on bacterial diversity and stability, but simulated grazing mitigates these effects

Frontiers in Microbiology
IntroductionNitrogen addition and grazing, as common management tools in grasslands, alter the structure and function of soil microbial communities and have far-reaching effects on grassland ecosystems.

Effects of short-term drought, nitrogen application and their interactions on the composition and functional genes of soil microbial communities in alfalfa grassland on the Loess Plateau

Frontiers in Sustainable Food Systems, 2023
Drought and nitrogen addition are important factors influencing soil microorganisms and changes in the soil environment. In the future, droughts will become more frequent, shorter, and more severe.

Nitrogen on microbial and global scales [PDF]

New Phytologist, 1998
Several temporal and spatial scales have been considered during the Symposium, and the presentations by Wallenda & Kottke (1998) and by Norby (1998) represent two extreme points in a wide range. They both deal with short and long‐term impacts on the local as well as the global scale. I present here a few additional thoughts, and a subject that both
