“…As a result, compared with the initial feedstock, the final product of composting (i.e., compost) is more stable with a lower proportion of labile organic C and N compounds, higher NO 3 − /NH 4 + ratio, and lower C:N ratio [ 93 ]. Accordingly, composted manure typically has different effects on the structure and function of the soil microbiome than raw manure [ 7 , 94 ]. Compost application to soils has been shown to induce short-term increases in the abundance of nitrifying and denitrifying microorganisms, resulting in N 2 O production [ 30 ].…”

The use of organic fertilizers constitutes a sustainable strategy to recycle nutrients, increase soil carbon (C) stocks and mitigate climate change. Yet, this depends largely on balance between soil C sequestration and the emissions of the potent greenhouse gas nitrous oxide (N2O). Organic fertilizers strongly influence the microbial processes leading to the release of N2O. The magnitude and pattern of N2O emissions are different from the emissions observed from inorganic fertilizers and difficult to predict, which hinders developing best management practices specific to organic fertilizers. Currently, we lack a comprehensive evaluation of the effects of OFs on the function and structure of the N cycling microbial communities. Focusing on animal manures, here we provide an overview of the effects of these organic fertilizers on the community structure and function of nitrifying and denitrifying microorganisms in upland soils. Unprocessed manure with high moisture, high available nitrogen (N) and C content can shift the structure of the microbial community, increasing the abundance and activity of nitrifying and denitrifying microorganisms. Processed manure, such as digestate, compost, vermicompost and biochar, can also stimulate nitrifying and denitrifying microorganisms, although the effects on the soil microbial community structure are different, and N2O emissions are comparatively lower than raw manure. We propose a framework of best management practices to minimize the negative environmental impacts of organic fertilizers and maximize their benefits in improving soil health and sustaining food production systems. Long-term application of composted manure and the buildup of soil C stocks may contribute to N retention as microbial or stabilized organic N in the soil while increasing the abundance of denitrifying microorganisms and thus reduce the emissions of N2O by favoring the completion of denitrification to produce dinitrogen gas. Future research using multi-omics approaches can be used to establish key biochemical pathways and microbial taxa responsible for N2O production under organic fertilization.

“…The relative abundance of Proteobacteria in different treatment tests was the highest, which was in accordance with previous studies. Ye found that Proteobacteria was the dominant bacteria in corn-field soil [33]. It was known that Proteobacteria can participate in the biological cycle of essential mineral nutrients in the soil; the high proportion of Proteobacteria in rhizosphere soil is beneficial to the maintenance of fertility and plant growth [34].…”

Agricultural fertilization significantly affects nutrients cycling in paddy soils. However, there are few systematic studies on the response of the application of livestock manure and corresponding organic fertilizer resulting in the microorganism and its nutrients entering farmland. Short-term application of pig manure and its corresponding organic fertilizer on the microorganisms of paddy fields were investigated. High-throughput sequencing technology was conducted to comprehensively study the microbial community composition and structure. Our results showed that organic fertilizer effectively enhanced nutrient substances such as nitrogen, phosphorus, and potassium at ripening stage and reduced the pH of soil, benefitting the soil fertility and the growth of rice. Though application of pig manure maintained higher microbial diversity, it increased the relative abundance of several pathogenic bacteria, which could threaten the soil health of the paddy fields. A large number of pathogenic bacteria can be reduced through composting pig manure to organic fertilizer. Nitrifying and denitrifying bacteria such as Anaerolineaceae, Pseudarthrobacter, Bacillus, and Nitrospira in the paddy soil were significantly promoted. The heavy metals such as Pb, Cr, and Cd, and nutrient substances such as phosphorus, as well as temperature, have important influences on the microbial compositions in ripening stage. The correlation analysis revealed more correlation efficiencies were observed with manure application, especially with the application of organic fertilizer. This study will provide a theoretical basis for improving land productivity and sustainable development in paddy fields.

“…Some recent studies suggest that pig and chicken manure significantly increases the abundance of soil bacteria by correlating with an increase in total soil nitrogen. Meanwhile, composted pig manure reduced the amount of some organotrophic bacteria [18]. Some research shows the advantage of granular organic fertilizers over ordinary manure [19].…”

Soil microorganisms are one of the main indicators used for assessing the stability of the soil ecosystem, the metabolism in the soil, and its fertility. The most important are the active soil microorganisms and the influence of the fertilizer applied to the soil on the abundance of these microorganisms. We aimed to investigate how the applied organic fertilizers affect the most active soil microorganisms, which determine the soil fertility and stability. Fungi, yeast-like fungi abundance, and abundance of three physiological groups of bacteria were analyzed: non-symbiotic diazotrophic, organotrophic, and mineral nitrogen assimilating. This study is valuable because relatively few similar studies have been performed on infertile Lithuanian soils. The first results of a long-term study were obtained. The results show the effect of fertilizers on trends in the changes of microorganism community diversity; however, more analysis is needed to assess the impact of organic fertilizers on the most active soil microorganisms. Therefore, the investigation was continued. The results of the 2020 quantitative analysis of culturable soil microorganisms show that the highest abundance of organotrophic and non-symbiotic diazotrophic bacteria were recorded during the summer season. Meanwhile, the abundance of bacteria assimilating mineral nitrogen and fungi was higher in autumn. Agrochemical parameters were determined at the beginning of the experiment. The highest concentration of Nmin in the soil was determined after fertilizing the plants with the combination of granulated poultry manure (N170) + biological substance Azotobacter spp. The yield of barley was calculated. It was found that the highest yield of spring barley in 2020 was obtained by fertilizing the experimental field with organic in combination with mineral fertilizers.
