Agriculture is responsible for 30–50% of the yearly CO2, CH4, and N2O emissions. Soils have an important role in production consumption these greenhouse gases (GHGs), with soil aggregates inhabiting microbes proposed to function as biogeochemical reactors, processing gases. Here we studied, first time, relationship between GHG fluxes aggregate stability determined via laser diffraction analysis (LDA) agricultural soils, well effect sustainable management strategies thereon. Using static...
Conventional agricultural activity reduces the uptake of potent greenhouse gas methane by soils. However, recently observed improved capacity soils after compost application is promising but needs mechanistic understanding. In this study, potential and microbiomes involved in cycling were assessed green household-compost with without pre-digestion. bottle incubations different composts both high near-atmospheric concentrations (∼10.000 & ∼10 ppmv, respectively), showed highest rates (up to...
Process technologies, such as composting, anaerobic digestion, or lactic acid fermentation, greatly influence the resulting organic amendments (OAs) characteristics even when same raw material is used. However, it still unclear how these process technologies indirectly modify effect of OAs on soil microbial activity and aggregation. To determine OA produced using pre-treatment aggregation, we ran a column experiment in which applied compost, digestate fermentation product made model...
Proteins are secreted throughout the mycelium of Aspergillus niger except for sporulating zone. A link between sporulation and repression protein secretion was underlined by finding that inactivation gene flbA results in mycelial colonies secrete proteins colony. However, ΔflbA strain hyphae also lyse have thinner cell walls. This pleiotropic phenotype is associated with differential expression 36 predicted transcription factor genes, one which, rpnR, inactivated this study. Sporulation,...
<p>Methane (CH<sub>4</sub>) is a potent greenhouse gas contributing to climate change, with global warming potential of 24x CO<sub>2</sub> on 100-year time-frame. More importantly, the atmospheric methane concentration has been rising rapidly in last decade. Soils are as yet only known biological sink for methane, but uptake capacity agricultural soils substantially reduced when compared native soils. This may be due...
The use of organic amendments (OAs) increases SOM and could be utilized to mitigate climate change. OAs produced via composting, anaerobic digestion, or lactic-acid fermentation (Bokashi-like ferments), even when using the same initial substrate, show significant differences in their properties. This study aimed investigate effect different obtain new insights role OA quality on soil properties, especially build-up. We used columns compare compost, solid-fraction digestate ferments made a...
