Straw return combined with water-saving irrigation increases microbial necromass accumulation by accelerating microbial growth-turnover in Mollisols of paddy fields

Geoderma
Soil microorganisms are key to the flow of carbon through soils. As the most carbon-rich soils, Mollisols are very sensitive to disturbance and more prone to be carbon sources than carbon sinks. To understand how the microbial physiology [i.e., microbial

A model of nitrous oxide evolution from soil driven by rainfall events: 1. Model structure and sensitivity [PDF]

, 1992
This paper describes a rain-event driven, process-oriented simulation model, DNDC, for the evolution of nitrous oxide (N2O), carbon dioxide (CO2), and dinitrogen (N2) from agricultural soils.

Spectrophotometric method for quantification of soil microbial biomass carbon

African Journal of Biotechnology, 2016
The search for more suitable alternatives in analytical processes is a strategy to reduce environmental damages. The present study aimed to quantify the soil microbial biomass carbon (SMB-C), establishing a comparison between the methods involving quantification of SMB-C by titration of the samples with ferrous sulfate ammonia and molecular absorption ...

Soil biochemistry and microbial activity in vineyards under conventional and organic management at Northeast Brazil. [PDF]

, 2011
The São Francisco Submedium Valley is located at the Brazilian semiarid region and is an important center for irrigated fruit growing. This region is responsible for 97% of the national exportation of table grapes, including seedless grapes. Based on the

Estimation of microbial biomass carbon and nitrogen in Bangladesh soils

Soil Science and Plant Nutrition, 1991
Abstract In order to estimate the microbial biomass content and to quantify the amount of available plant nutrients derived from microbial biomass in Bangladesh soils, biomass-C, -N, and available-N contents using samples from 8 soils were measured by applying the chloroform fumigation and drying-rewetting methods, respectively.

Soil Carbon Release and Microbial Biomass Characteristics in Different Pinus massoniana Forests in Three Gorges Reservoir area [PDF]

长江科学院院报
[Objective] As a hotspot region of soil respiration and carbon pool dynamics, the Three Gorges Reservoir area is most extensively covered by Pinus massoniana forests, whose soil organic carbon storage is the largest among all forest types.

Differences in soil biological activity by terrain types at the sub-field scale in central Iowa US. [PDF]

PLoS ONE, 2017
Soil microbial communities are structured by biogeochemical processes that occur at many different spatial scales, which makes soil sampling difficult.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Responses of soil microbial biomass, microbial entropy and soil-microorganism stoichiometry imbalance to different utilization patterns in the artificial grassland of karst desertification area

Frontiers in Microbiology, 2023
Different utilization patterns can alter the C, N, P cycles and their ecological stoichiometry characteristics in grassland soils. However, the effects of different utilization patterns on soil microbial biomass, microbial entropy and soil-microorganism ...

Microbial carbon use efficiency: accounting for population, community, and ecosystem-scale controls over the fate of metabolized organic matter [PDF]

, 2016
Microbial carbon use efficiency (CUE) is a critical regulator of soil organic matter dynamics and terrestrial carbon fluxes, with strong implications for soil biogeochemistry models.
