“…Our results showed that the MF treatment significantly enhanced the OM content of the soil. Our results are in line with studies published by Gryta et al [33] and Cesarano et al [34] who reported the beneficial effect of OM in replenishing soil microbiome and fertility. Optimum productivity of plants can be ensured only with vital bio-available nutrients in the soil [33,34].…”

The current high rate of food waste production, concomitant with the global increase in population and food demand, has adverse effects on environmental and socio-economic conditions. However, food waste has been shown to be an efficient and safe source of fertilizer in agriculture practice. Moreover, minimizing the application of chemical fertilizers is a goal of sustainable agriculture. Considering these facts, we aimed to compare the effect of chemical fertilizer (CF-3,8 g·pot−1) and different doses of mixed food waste-derived fertilizer (MF-10.6 g·pot−1), two-fold MF (MF × 2), four-fold MF (MF × 4), and six-fold MF (MF × 6) in a popular salad crop, Lactuca sativa (lettuce). Our results showed the growth rates of lettuce plants receiving CF, MF, and MF×2 applications were essentially the same; however, plant biomass significantly dropped with MF × 6 treatment. The CF, MF, and MF × 2 treatments enhanced the chlorophyll content, chlorophyll fluorescence, and photosynthetic rate of the plants and improved transpiration efficiency and stomatal conductance. With respect to mineral elements, the K+ content was significantly enhanced with MF × 2 and MF × 4 treatment, whereas MF × 6-treated plants showed lower concentrations of Ca, P, Mg, and K+ as well as higher Na+ concentration. Biochemical analysis showed the elevation of abscisic acid level with increasing dose of MF, except in the MF × 6 treatment. The level of super oxide dismutase (SOD) dropped with CF treatment, was unchanged with MF, and significantly increased in MF×2 and MF × 4 treated plants. Subsequently, higher flavonoid content was observed in MF×2 and MF×4 plants. The current results demonstrate the potential of food waste as a source of organic fertilizer and a significant substitute for chemical fertilizer in the conventional agricultural practice driven by high production cost and environmental pollution.

“…At the same time, the enzymes related to organic carbon mineralization, i.e., K05349 (beta-glucosidase [EC: 3.2.1.21]) and K15371 (glutamate dehydrogenase (GDH2) [EC: 1.4.1.2]), decreased. These results showed that the soil management under rainfed conditions proposed in this study (i.e., compost amendment and incorporation of weed biomass in an olive grove) affected some pathways of soil metabolism and environmental information processing in a manner comparable to that evidenced by other authors and for conservation management [54,55], promoting the humification of both exogenous and natural organic carbon [56]. Finally, we did not find significant differences in the global metabolic pathways related to the P cycle (K01113_K01077_alkaline phosphatase).…”

A collapse of soil microbial diversity, mainly due to chemical inputs, has been reported to lead to the degradation of conventional agroecosystems. The use of compost from urban and agricultural waste management, in order to achieve a net gain in the storage of C, is an adequate management of agricultural soils, especially in rainfed conditions. However, the great variability of composts of different maturity and origins and of the soils to which they are added limits the ability to predict the impact of these amendments on the dynamics of soil microbial communities. This study was designed to gain insights on the effect of exogenous organic matter management on the soil bacterial community and its contribution to key functions relevant to agricultural soils. To achieve this, two different types of compost (alperujo or biosolids composts) at two doses were used as soil amendments twice for 3 years in a rainfed olive grove ecosystem. A metagenomic analysis was carried out to assess the abundance and composition of the soil bacterial communities and predicted functions. We only detected a minor and transitory effect on the bacterial abundance of the soil, the structure of the community and the potential functions, less related to the dose or the type of compost than to seasonal variations. Although the result suggests that the soil bacteria were highly resilient, promoting community stability and functional resilience after the addition of the two composts, more efforts are necessary to assess not only the resulting soil microbial community after organic fertilization but the intrinsic microbial community within the organic amendment that acts as an inoculum, and to what extent the changes in its dose could lead to the functionality of the soil.

“…Different fertilization methods, both organic and inorganic, are known to influence the activity and biodiversity of soil microorganisms. The introduction of various substances to the soil may change the composition of indigenous microbiota and modify processes taking place in the soil environment [35][36][37].…”

“…The CLPP analysis using BIOLOG plates was prepared in the following way: 1 g of fresh soil was suspended in 99 mL of sterile saline peptone water and shaken for 20 min at 20 • C before being incubated for 30 min at 4 • C. Afterwards, each well of the BIOLOG ECO plate and FF plate was inoculated with a prepared suspension of 120 µL and 100 µL respectively, and incubated at 23 • C. Absorbance readings were performed at 590 nm in the case of ECO plates and at 750 nm as for FF plates with a BIOLOG MicroStation plate reader (Biolog ® , Hayward, CA, USA) every 24 h for 216 incubation hours. Detailed procedures of the analyses were described by Wolińska et al [135] and Gryta et al [35].…”

Regarding the unfavourable changes in agroecosystems resulting from the excessive application of mineral fertilizers, biopreparations containing live microorganisms are gaining increasing attention. We assumed that the application of phosphorus mineral fertilizer enriched with strains of beneficial microorganisms contribute to favourable changes in enzymatic activity and in the genetic and functional diversity of microbial populations inhabiting degraded soils. Therefore, in field experiments conditions, the effects of phosphorus fertilizer enriched with bacterial strains on the status of soil microbiome in two chemically degraded soil types (Brunic Arenosol – BA and Abruptic Luvisol – AL) were investigated. The field experiments included treatments with an optimal dose of phosphorus fertilizer (without microorganisms – FC), optimal dose of phosphorus fertilizer enriched with microorganisms including Paenibacillus polymyxa strain CHT114AB, Bacillus amyloliquefaciens strain AF75BB and Bacillus sp. strain CZP4/4 (FA100) and a dose of phosphorus fertilizer reduced by 40% and enriched with the above-mentioned bacteria (FA60). The analyzes performed included: the determination of the activity of the soil enzymes (protease, urease, acid phosphomonoesterase, β-glucosidase), the assessment of the functional diversity of microorganisms with the application of BIOLOGTM plates and the characterization of the genetic diversity of bacteria, archaea and fungi with multiplex terminal restriction fragment length polymorphism and next generation sequencing. The obtained results indicated that the application of phosphorus fertilizer enriched with microorganisms improved enzymatic activity, and the genetic and functional diversity of the soil microbial communities, however these effects were dependent on the soil type.
