Abstract Soil microorganisms act as gatekeepers for soil–atmosphere carbon exchange by balancing the accumulation and release of soil organic matter. However, poor understanding mechanisms responsible hinders development effective land management strategies to enhance storage. Here we empirically test link between microbial ecophysiological traits topsoil content across geographically distributed soils use contrasts. We discovered distinct pH controls on accumulation. Land intensification in...
The contribution of low-abundance microbial species to soil ecosystems is easily overlooked because there considerable overlap between metabolic abilities (functional redundancy) dominant and subordinate species. Here we studied how loss less abundant bacteria affected the production antifungal volatiles, an important factor in natural control soil-borne pathogenic fungi. We provide novel empirical evidence that bacterial leads a decline volatiles suppress root pathogens. By using...
There is increasing evidence that microbial volatiles (VOCs) play an important role in natural suppression of soil-borne diseases, but little known on the factors influence production suppressing VOCs. In current study we examined whether a stress-induced change soil community composition would affect by soils VOCs plant-pathogenic oomycete Pythium. Using pyrosequencing 16S ribosomal gene fragments compared bacterial communities sandy had been exposed to anaerobic disinfestation (AD),...
The current focus on intensification and maximizing productivity in agriculture can endanger soil biota the ecosystem services they provide such a way that it acts counterproductive increases dependence external inputs. In this study, we aimed to identify factors are most limiting for restoration of their sandy soils. To end, assessed microarthropod communities, relationship with aboveground food web effect organic matter decomposition, two land-use types: grasslands agricultural land use...
Peat meadows in the Netherlands emit around 3% of country’s total CO2 emissions. Measures to reduce emissions agricultural peat areas are mostly based on water management, clay-in-peat project researches a soil measure: addition 1-2 cm clay top meadow. In lab experiments, where and completely mixed, some combinations show reduction CO2. It is still unclear what working mechanisms are. These could vary from clay-peat-complex formation binding enzymes or changes pore structure.In...
Dutch peat meadows, once carbon sinks, now contribute nearly 4% of the country’s CO2 emissions, releasing 6.9 Mton CO2-eq annually due to historical drainage and conversion agricultural lands. Drainage exposes organic-rich soils oxygen, leading increased microbial activity, organic matter decomposition, associated thereby adding global warming.We hypothesize that clay addition meadows will reduce soil respiration, as previously observed in mineral soils. The reduction is caused by...
Over 80 % of the Dutch peatland is permanent grassland for agricultural use. To maintain these peat meadows land drained, resulting in carbon decomposition and greenhouse gas emissions. Currently most measures to reduce emissions from drained are hydrological, limiting exposure oxygen. In our research we aim study whether a non-hydrological measure -the enrichment with clay minerals- can CO2 emissions.Previous indicate that content might be linked degradation. Several studies show...
There is a global pattern of decline in insect abundance and diversity. The presence residues pesticides animal feed fly treatments results polluted dung, which may hamper the survival insects feeding breeding on dung. To study route from pesticide contamination dung to pats, two experiments were performed. In Experiment 1, dairy cows collected eight Dutch farms (six conventional, organic). All feeds ration as well analysed for pesticides. 2, was herd spiked with four concentrations...
In three dairy grasslands on peat, minerals were added to manipulate the soil Ca:Mg ratio with or without effect pH. The responses of properties and grass N yield measured. CaCO3 application led higher pHKCl compared untreated control, decreased Ntotal Ctotal, increased P availability. Grass in first year by only 6% reduction Ntotal, but not second year. A pH SOM decomposition, especially soils high MgCO3 reduced ratio, had little influence parameters no yield. contrast, CaSO4 MgSO4 did most...
There is increasing evidence showing that microbes can influence plant-insect interactions. In addition, various studies have shown aboveground pathogens alter the interactions between plants and insects. However, little known about role of soil-borne in It also not how environmental conditions, steer performance pathogens, might these microbe-plant-insect Here, we studied effects pathogen Rhizoctonia solani on aphids (Sitobion avenae) using wheat (Triticum aestivum) as a host. greenhouse...
Organic farming is increasingly promoted as a means to reduce the environmental impact of artificial fertilizers, pesticides, herbicides, and antibiotics in conventional dairy systems. These factors potentially affect microbial communities production stages (soil, silage, dung, milk) entire farm cycle. However, understanding whether microbiota representative different reflects agricultural practices - such versus organic unknown. Furthermore, translocation community across scarcely studied....
Abstract Soils are subjected to multiple anthropogenic modifications, but the synergistic impacts of simultaneous environmental stressors on below‐ground communities poorly understood. We used a large‐scale (1152 plots), long‐term (26 years), multi‐factorial grassland experiment assess impact five common agricultural practises (pesticides, herbicide, liming, fertilizers and grazing exclusion) their interactive effects composition activity soil microbial communities. confirmed that pH...
