BIOMASSA MICROBIANA E SUA CORRELAÇÃO COM A FERTILIDADE DE SOLOS EM DIFERENTES SISTEMAS DE CULTIVO

open access: yesColloquium Agrariae, 2010
The role of microorganisms in the soil is to mediate processes related to management the ecological balance. Thus, they can be sensitive indicators of changes in soil quality. Microorganisms have the ability to quickly respond to changes in soil quality,

Development of Collembolans after coversion towards organic farming [PDF]

open access: yes, 2006
In Northern Germany, a diverse and complex experimental farm of the Federal Agricultural Research Centre (FAL) was set-up in 2001 covering all main aspects of organic farming. Previously, the 600 ha farm had been managed conventionally.

Global ecological predictors of the soil priming effect. [PDF]

open access: yes, 2019
Identifying the global drivers of soil priming is essential to understanding C cycling in terrestrial ecosystems. We conducted a survey of soils across 86 globally-distributed locations, spanning a wide range of climates, biotic communities, and soil ...

Diversity of Pharmaceuticals Enhances Antibiotic Resistance in the Invertebrate Gut via Biofilm‐Mediated Mechanisms

open access: yesAdvanced Science, EarlyView.
Pharmaceutical diversity acts as an independent driver of antibiotic resistance in soil invertebrates. While bulk soil remains unaffected, the collembolan gut microbiome exhibits significant resistance gene enrichment under complex chemical exposure and diurnal warming.

Effects of Mixing Feldspathic Sandstone and Sand on Soil Microbial Biomass and Extracellular Enzyme Activities—A Case Study in Mu Us Sandy Land in China

open access: yesApplied Sciences, 2019
Microbial biomass, extracellular enzyme activity, and their stoichiometry in soil play an important role in ecosystem dynamics and functioning. To better understand the improvement of sand soil quality and the limitation of soil nutrients after adding ...

Sources of nitrogen for winter wheat in organic cropping systems [PDF]

open access: yes, 2013
In organic cropping systems, legumes, cover crops, residue incorporation, and manure application are used to maintain soil fertility, but the contributions of these management practices to soil nitrogen (N) supply remain obscure.

Bioenergy Cropping Reduces the Spatiotemporal Scaling of Soil Bacterial Biodiversity

open access: yesAdvanced Science, EarlyView.
Consistent with patterns observed in plant and animal communities, soil bacterial communities exhibit significant species–time–area and phylogenetic–time–area relationships independent of nested structure. Bioenergy cropping significantly reduces the spatiotemporal scaling rates, particularly in sandy loam soils.

Grazing impact on soil chemical and biological properties under different plant cover types in a mountain area of Southern Italy. [PDF]

open access: yes, 2006
Grazing can contribute to soil degradation by compaction due to roaming of livestock and loss of herbaceous cover, affecting also soil microbial community.

Microbial carbon use efficiency predicted from genome-scale metabolic models [PDF]

open access: yes, 2019
Respiration by soil bacteria and fungi is one of the largest fluxes of carbon (C) from the land surface. Although this flux is a direct product of microbial metabolism, controls over metabolism and their responses to global change are a major uncertainty

Predictive model of soil molecular microbial biomass

open access: yesEcological Indicators, 2016
Abstract Preservation and sustainable use of soil biological communities represent major challenges in the current agroecological context. However, to identify the agricultural practices/systems that match with these challenges, innovative tools have to be developed to establish a diagnosis of the biological status of the soil.
