“…Instead, increasing the crops facilitates the abundance of plant residues returned in the soil, which increases the total carbon content and improves the activity of soil enzymes that decrease the C/ N ratio by decomposing abundant residues resulting from the application of long-term mineral fertilization. Thus, it can be concluded that the optimal proportion of organic fertilizers is the ideal approach to optimize the quality of the soil and implicitly its productivity as well as the abundance of bacterial strains [47,51]. Additionally, similar data were found in a long-term study, when Dhillon et al [52] also reported greater SOC content in upper soil layers under shallow ploughless tillage compared to other tillage types.…”

“…Tillage type was not a statistically significant factor for the abundance of micromycetes. Other researchers determined that by deep plowing, organic residues and mineral fertilizers are introduced in depth, thus intensifying the microbiological processes throughout the mass of the arable layer [47,48]. In our research, deep loosening of the soil significantly reduced micromycetes and cellulose-degrading bacterial populations on the decomposable substrate.…”

“…The accumulation of organic matter and inorganic nutrients in the surface layer of unplowed soil creates an environment in which biological activity is strongly stimulated [47]. Tillage type significantly influenced the abundance of physiological groups of microorganisms on the decomposing substrate.…”

Soil microorganism diversity has a close relation with soil function, and the changes in the composition of the soil microbial population can directly affect it. The aim of this study was to identify the bacterial community composition and determine the main soil chemical and physical properties formed by the different tillage systems. In the experiment, we analyzed the combination of three tillage systems and four organic fertilizers. Soil samples were taken from the two layers of the soil profile: the upper 0–10 cm and the lower 10–20 cm. The composition and diversity of soil bacterial communities were assessed by the sequencing of 16S rRNA genes. Results revealed that the highest biodiversity was found in the soil with shallow ploughless tillage and enriched with farmyard manure. Actinobacteria and Proteobacteria were the dominant bacterial species across all treatments. Their total abundance varied between 26% and 36% in the different analyzed agroecosystems. For the Dystric Bathygleyic Glossic Retisol, shallow ploughless tillage is the most suitable tillage system, as it creates favorable conditions for the accumulation of organic carbon in the soil under the Western Lithuania climate conditions.

“…Moreover, the hydrolysis and acidification stages are extremely influenced by environmental factors such as inocula, substrate, pH, temperature, and hydraulic retention time (HRT) [8][9][10][11]. Some studies have investigated numerous pretreatment methods, such as physical, chemical, and biological approaches, separately or in combination, to enhance the hydrolysis step [12][13][14][15][16]. Biological pretreatment and bioaugmentation have been recognized as promising approaches to increase VFA yield since these methods are eco-friendly and affordable.…”

Volatile Fatty Acid Production from Food Waste Leachate Using Enriched Bacterial Culture and Soil Bacteria as Co-Digester

et al. 2021

The production of volatile fatty acids (VFAs) from waste stream has been recently getting attention as a cost-effective and environmentally friendly approach in mechanical–biological treatment plants. This is the first study to explore the use of a functional bacterium, AM5 isolated from forest soil, which is capable of enhancing the production of VFAs in the presence of soil bacteria as a co-digester in non-strict anaerobic fermentation processes of food waste leachates. Batch laboratory-scale trials were conducted under thermophilic conditions at 55 °C and different pH values ranging from approximately 5 to 11, as well as under uncontrolled pH for 15 days. Total solid content (TS) and volatile solid content (VS) were observed with 58.42% and 65.17% removal, respectively. An effluent with a VFA concentration of up to 33,849 mg/L (2365.57 mg/g VS; 2244.45 mg/g chemical oxygen demand (COD)-VFA VS; 1249 mg/g VSremoved) was obtained at pH 10.5 on the second day of the batch culture. The pH resulted in a significant effect on VFA concentration and composition at various values. Additionally, all types of VFAs were produced under pH no-adjustment (approximately 5) and at pH 10.5. This research might lead to interesting questions and ideas for further studies on the complex metabolic pathways of microbial communities in the mixture of a soil solution and food waste leachate.

“…However, the addition of mineral fertilizers to organic (green manure and farmyard manure) fertilizers showed a significant increased plant biomass production, which upon incorporation stimulates soil biological activity [56]. Using organic matter in plant fertilization increases the microbial/chemical actions and properties of soils [57]. A balanced application of fertilizers concludes to the formation of favorable conditions for the development of microorganisms, growth of plants and for an intense and lasting enzymatic activity [58].…”

Application of Granular and Non-Granular Organic Fertilizers in Terms of Energy, Environmental and Economic Efficiency

Granular organic fertilizers have been increasingly used in agriculture due to the longer delivery of nutrients to plants and the milder impact on the environment. The aim of this study was to determine the energy, environmental and economic efficiency of granular and non-granular organic fertilizers. Four technological scenarios of organic fertilizer use were used for comparative assessment: (1) manure fertilization (16.0 t ha−1), (2) manure fertilization (30.0 t ha−1), (3) manure pellet fertilization (2.0 t ha−1), and (4) fertilization with meat and bone meal pellets (0.7 t ha−1). Experimental studies using the mass flow method of laser spectroscopy were performed to evaluate the comparative environmental impact of granular and non-granular organic fertilizers. Economic assessment was performed for mechanized technological operations of loading, transportation and distribution of organic fertilizers, estimating the price of aggregates used and fuel consumed, the costs of individual technological operations and other indirect costs. The results showed that for mechanized technological operations, when fertilizing with granular organic manure and meat and bone meal fertilizer, energy consumption is 3.2 to 4.0 times lower compared to fertilization with manure. The average ammonia (NH3) emissions from granular organic fertilizers were found to be six times lower than from non-granular organic fertilizers. The lowest costs for mechanized works were incurred when using meat and bone meal pellets, the highest economic benefits of organic fertilizers by elements was when using manure 30 t ha−1, and the highest costs for organic fertilizers were incurred when using manure pellets.
