Tillage, Mulching and Nitrogen Fertilization Differentially Affects Soil Microbial Biomass, Microbial Populations and Bacterial Diversity in a Maize Cropping System

Frontiers in Sustainable Food Systems, 2021
Determination of biologically active components of the soil organic matter, such as soil microbial biomass carbon (C) and nitrogen (N) can be used as indicators for variations in soil productivity due to changes in soil management.

Fallow effect on soil microbial biomass

Mongolian Journal of Agricultural Sciences, 2022
Indeed microbial communities are involved in 80–90% of the occurring processes in the soil (plant productivity, biogeochemical cycling, organic matter decomposition, etc.). Our study assesses the influence of the fallow system on soil bacterial biomass in fallow fields in 2021.

Investigation on effect of forest plantation of Alnus ghutinosa L. (Gaertn.) and Pinus taeda L. on soil microbial activity and biomass (case study: Geisom site, west of Guilan province, Iran) [PDF]

تحقیقات جنگل و صنوبر ایران, 2012
Biological property is a best indicator for soil quality identification due to its relationships with soil nutrient cycle, respiration, microbial biomass and enzymes activity.

Soil Microbial Biomass Across a Gradient of Preserved Native Cerrado

Floresta e Ambiente, 2018
The different physiognomies and soil conditions across the Cerrado gradient may influence soil microbial biomass. The present study evaluated the soil microbial biomass and enzyme activity across a preserved Cerrado gradient and correlated these with ...

Drivers and trends of global soil microbial carbon over two decades

Nature Communications, 2022
Soil microorganisms are central to sustain soil functions and services, like carbon and nutrient cycling. Currently, we only have a limited understanding of the spatial-temporal dynamics of soil microorganisms, restricting our ability to assess long-term

Linking Soil Microbial Properties with Plant Performance in Acidic Tropical Soil Amended with Biochar

Agronomy, 2018
Soil microbial properties are frequently used as indicators of soil fertility. However, the linkage of these properties with crop biomass is poorly documented especially in biochar amended soil with high carbon:nitrogen (C:N).

Microbial Biomass and Activity in Lead-Contaminated Soil [PDF]

Applied and Environmental Microbiology, 1999
ABSTRACT Microbial community diversity, potential microbial activity, and metal resistance were determined in three soils whose lead contents ranged from 0.00039 to 48 mmol of Pb kg of soil −1 . Biomass levels were directly related to lead content. A molecular analysis of 16S rRNAs suggested that each soil

Microbial regulation of soil carbon properties under nitrogen addition and plant inputs removal [PDF]

PeerJ, 2019
Background Soil microbial communities and their associated enzyme activities play key roles in carbon cycling in terrestrial ecosystems. Soil microbial communities are sensitive to resource availability, but the mechanisms of microbial regulation have ...

Adenosine triphosphate and microbial biomass in soil

Soil Biology and Biochemistry, 1979
Two methods for measuring adenosine 5'-triphosphate (ATP) in soil were compared, one based on extraction with NaHCO3-CHCl3 and thel other on extraction by a trichloracetic acid-phosphate-paraquat reagent. Recoveries of added ATP were greater with the NaHCO3-CHCl3 reagent but the extraction of “native” soil ATP by NaHCO3-CHCl3 was only about a third of ...

Microbial responses to doses of cover plant straw in cerrado piauiense oxisol

Bioscience Journal, 2020
Carbon and nitrogen from the soil microbial biomass play a significant role in the rotation of C and N, and promote nutrient cycling. Thus, the objective of this study was to evaluate changes in the soil microbial biomass with growing doses of cover ...
