“…A probable reason is that the application of organic manure can improve the ventilation conditions of the soil and stimulate beneficial microbes ( Ding et al, 2017 ; Wen et al, 2020 ). It is intriguing that most of the saprotrophs in CFM are undefined, which might due to the differences in the compounds of manure and plant-origin materials ( Li et al, 2021 ). This may also be an explanation for the decreased effects of CFO and CFS on the fungal community than the effect showed by CFM, since the C sources provided by manure were thoroughly different from the C of living plants and plant residues.…”

Continuous cropping leads to the development of serious fungal diseases in tobacco plants and depleted yield of tobacco (Nicotiana tabacum), which can be mitigated by organic fertilization. Yet, we know little about how organic fertilizers affect the fungal community of continuous cropping tobacco soil. In this study, we investigated the soil fungal community after 11 years of tobacco planting with chemical fertilization (CF) or chemical fertilization combined with organic fertilizers obtained from plant or animal origin, including oil cake (CFO), straw (CFS), and farmyard fertilizer (CFM). The predominant phyla of Ascomycota (70%) and Mortierellomycota (15%) were identified in all the treatments. A significantly higher proportion of Pyrenochaetopsis and lower relative abundance of Sordariomycetes were observed in the CFM group compared to the controls. Compared to CF and non-fertilized control (CK), CFO and CFS led to higher species richness (P < 0.05), while CFM led to a less uniform fungal community, indicated by lower Shannon and higher Simpson diversity indices (P < 0.05). Pearson’s correlation and redundancy analysis suggested that fertilizations primarily influenced the fungal community by altering the soil nutrient conditions, among which soil organic carbon and total phosphorus significantly correlated with the fungal diversity and community composition (P < 0.05). Notably, FUNGuild annotation suggested that while other treatments showed no significant effect on the fungal trophic modes, CFM strongly increased the abundance of saprotrophic fungi by more than 30% (P < 0.05), thus preventing the prevalence of potential pathotypes and symbionts. The results suggest that the type of organic fertilizers is essential to the long-term effects of organic application on the fungal community, and the animal-origin manure seems to be a better choice than plant-origin materials in continuous cropping tobacco fields.

Conventional farming systems are highly reliant on chemical fertilizers (CFs), which adversely affect soil quality, crop production and the environment. One of the major current challenges of current agriculture is finding ways to increase soil health and crop yield sustainably. Manure application as a substitute for CF is an alternative fertilization strategy for maintaining soil health and biodiversity. However, little is known about the complex response of soil bacterial communities and soil nutrients to manure and CFs application. This study reports the response of soil nutrients, rice yield, and soil microbial community structure to 2 years of continuous manure and CFs application. The study consisted of six treatments: no N fertilizer control (Neg-Con); 100% CF (Pos-Con); 60% cattle manure (CM) + 40% CF (High-CM); 30% CM + 70% CF (Low-CM); 60% poultry manure (PM) + 40% CF (High-PM), and 30% PM + 70% CF (Low-PM). We used high-throughput sequencing of 16S ribosomal RNA gene amplicons to characterize the soil bacterial communities. Results revealed that the addition of manure significantly altered the soil bacterial community composition and structure; and enhanced the relative abundance of phyla Proteobacteria, Chloroflexi, Firmicutes, Acidobacteria, and Planctomycetes. Organic fertilizer treatments, particularly high CM and PM had the highest measured soil bacterial diversity of all treatments. Similarly, integrated application of manure and CFs increased the soil biochemical traits [i.e., pH, total N (TN), soil organic C (SOC), microbial biomass N (MBN), and microbial biomass C (MBC)] and rice grain yield. Average increases in SOC, TN, MBN, and MBC were 43.66, 31.57, 24.34, and 49.45%, respectively, over the years in the High-PM compared with Pos-Con. Redundancy analysis showed that the dominant bacteria phyla were correlated with soil pH, SOC, TN, and microbial biomass, but the relative abundance of Proteobacteria was strongly correlated with environmental factors such as soil pH, SOC, TN, and MBC. We employed a structural equation model to examine the relationship between microbial biomass, soil nutrients and grain yield among treatments. This analysis supported the hypothesis that soil nutrient content and availability directly affect rice grain yield while soil bacteria indirectly affect grain yield through microbial biomass production and nutrient levels. Overall, the findings of this research suggest that the integrated application of CF and manure is a better approach for improving soil health and rice yield.

“…Fertilization is widely regarded as one of the most prevalent and effective methods for managing agricultural production. The impact of different fertilization regimens on soil quality, encompassing soil nutrients, enzyme activities, and microbial biomass, has been extensively studied (Lin et al 2019;Li 2021a). In this study, the soil nutrient content increased as the fertilizer application rate increased.…”

Background and aims Fertilization is a critical management practice for improving soil fertility and increasing agricultural production. We still don't fully understand how biotic and abiotic variables interact with soil multifunctionality in the rhizosphere soil of legume-Gramineae mixtures following fertilization. Studies on the effects of fertilization on the bacterial composition of legume-Gramineae mixtures in particular geographical areas are scarce. Methods To tackle this matter, we set up five treatments: no fertilizer zone (CK, N0P0K0), nitrogen-phosphorus-potassium zone (NPK, N2P2K2), nitrogen-less zone (PK, N0P2K2), phosphorus-less zone (NK, N2P0K2), and potassium-less zone (NP, N2P2K0). The soil data were measured to assess the response mechanism of legume-Gramineae mixtures to fertilization management. Results The fertilization treatment resulted in a beneficial impact on the rhizosphere soil nutrients, enzyme activity, and biological characteristics, reaching the maximum under N2P2K2 treatment. The analysis of the bacterial community revealed that the oligotrophic taxa decreased primarily due to fertilizer addition, including Acidobacteria, and enhancing the copiotrophic taxa, such as Bacteroidetes and Proteobacteria, in the soil. Furthermore, according to FAPROTAX analysis, the results indicated variations in the function of the bacterial community in the rhizosphere soil of legumes and gramineae. Fertilization indirectly affected soil versatility by changing the diversity and composition of bacterial communities. Conclusions The bacterial community can be reshaped and the properties of the rhizosphere soil can be modified by different fertilization treatments, thus impacting the potential function of the bacterial community. This study has the potential to offer scientific guidance for the rational management of fertilization in legume-Gramineae mixtures.
