“…This increase in diversity within the soil bacterial community could either correspond to the emergence of endogenous rare OTUs with functional abilities better adapted to this new environment than the original one or to the invasion of soil community. While previous studies provided evidence suggesting soil invasion by manure-borne bacteria, they failed to distinguish surely allochthonous invaders from autochthonous OTUs that emerge because of environmental disturbance caused by the adjunction of exogenous matter [15,20]. In the same line, we showed that some OTUs favored in response to manure amendment were not detected in the manure-free soils although they were almost all detected in the manure.…”

“…Previous studies showed that amended soils durably differ from manure-free soils when considering the abiotic part of coalescence [12,13]. However, although the novel soil environment differs from the unamended one, the microbial community resulting from coalescence is generally relatively similar to that of the original one [14,15]. The rather imbalanced ratio between soil and manure matrices may partially explain this.…”

The fertilization of agricultural soil by organic amendment that may contain antibiotics, like manure, can transfer bacterial pathogens and antibiotic-resistant bacteria to soil communities. However, the invasion by manure-borne bacteria in amended soil remains poorly understood, being hardly observed. Here, we assessed the invasions of manure-borne bacteria during a coalescence event between manure and soil, in different soils and in the presence or absence of antibiotics. To this end, microcosms of four different soils were amended or not with manure at an agronomical dose and/or exposed or not to the antibiotic sulfamethazine (SMZ). After one month of incubation, the diversity, structure and composition of bacterial communities of the soils were assessed by 16S rDNA sequencing. The invasion of manure-borne bacteria was still perceptible one month after the soil amendment. The results obtained with the soil already amended in situ with manure six months prior to the experiment suggest that some of the bacterial invaders were established in the community over the long term. Even if differences were observed between soils, the invasion was mainly attributable to some of the most abundant OTUs of manure (mainly Firmicutes). SMZ exposure had a limited influence on soil microorganisms. It was significant in only one soil, where it enhanced the invasion potential of some manure-borne invaders.

Qualitative and Quantitative Characteristics of Soil Microbiome of Barents Sea Coast, Kola Peninsula

The soil microbiome of the Barents Sea coast of the Kola Peninsula is here characterized for the first time. The content of copies of ribosomal genes of archaea, bacteria, and fungi was determined by real-time PCR. Reserves and structure of biomass of soil microorganisms such as total biomass of fungi and prokaryotes, length and diameter of mycelium of fungi and actinomycetes, proportion of mycelium in biomass, number of spores and prokaryotic cells, proportion of small and large fungal propagules, and morphology of mycobiota spores were determined. The largest number of ribosomal gene copies was found for bacteria (from 6.47 × 109 to 3.02 × 1011 per g soil). The number of copies of ribosomal genes of fungi and archaea varied within 107–109 copies of genes/g soil. The biomass of microorganisms (prokaryotes and fungi in total) varied from 0.023 to 0.840 mg/g soil. The share of mycobiota in the microbial biomass ranged from 90% to 97%. The number of prokaryotes was not large and varied from 1.87 × 108 to 1.40 × 109 cells/g of soil, while the biomass of fungi was very significant and varied from 0.021 to 0.715 mg/g of soil. The length of actinomycete mycelium was small—from 0.77 to 88.18 m/g of soil, as was the length of fungal hyphae—an order of magnitude higher (up to 504.22 m/g of soil). The proportion of fungal mycelium, an active component of fungal biomass, varied from 25% to 89%. Most (from 65% to 100%) of mycobiota propagules were represented by specimens of small sizes, 2–3 microns. Thus, it is shown that, despite the extreme position on the mainland land of Fennoscandia, local soils had a significant number of microorganisms, on which the productivity of ecosystems largely depends.

“…It was also observed in the current study, that addition of rice residues (incorporation and mulching), green manuring and FYM increased the soil's bacterial and fungal populations when compared to chemical fertilizer application, rice-residue removal and rice-residue burning treatments. The decomposition of green manures and FYM favours microflora by providing both C and energy for growth and formation of new cell material, which further multiplies the soil microbial community in the decomposing OM, resulting in maximum amounts of microfauna in the soil ecosystem [77]. However, the application of chemical fertilizers affects microbial diversity in a number of ways [78].…”

This study evaluated the impact of conventional practices (fertilizer alone) and diverse farming approaches (such as green manuring, farmyard manure application, rice-residue incorporation, residue mulching, residue removal and residue burning) on soil attributes. A total of thirty-five farm sites were selected, with five sites (replications) for each farming approach system, which were used over the past three years in the study farms. Characterization of rice residues of all cultivars, green manure crop (sesbenia: Sesbania sesban) and decomposed farmyard manure samples showed differential behaviours for macronutrients and micronutrients. Continuous application of inorganic fertilizers significantly influenced soil attributes, especially electrical conductivity, nutrient contents, bacterial and fungal population and soil enzymatic attributes. The crop residue treatments favourably influenced the soil parameters over the control. Crop residue incorporation or burning significantly increased soil available potassium, microbial biomass, enzymatic activities and organic carbon when compared with applications of chemical fertilizer alone, while total nitrogen content was increased by residue incorporation. However, green manuring and farmyard manure applications showed inferior responses compared with residue management treatment. It is therefore recommended that bioresources should be managed properly to warrant improvements in soil properties, nutrient recycling and the sustainability for crop productivity, in order to achieve sustainable development goals for climate action.
