“…The analysis revealed that the abundance of N/P-associated genes was closely correlated with bacterial network clusters in module #8 and module #15, as well as the changes in TN and TP content in different parts of the pepper plants. Interestingly, certain microbial genera, such as Jatrophihabitans , Conexibacter (Wu et al ., 2022), Rhodanobacter (Wang et al ., 2022; Wu et al ., 2022), f_ 67-14 , Acidibacter (Song et al ., 2022), f_ Microscillaceae , and f_ Chitinophagaceae , were found to be enriched in specific pepper varieties and likely play significant roles in N/P cycling. On the other hand, high-abundance genera in YZ and BE cultivars, including Arthrobacter , Nitrosospira , Frankiales , Bacillus , Lysobacter , Sorangium , Conexibacter , and Leifsonia , have been reported to be involved in nitrification or nitrogen fixation processes (Hu et al ., 2021; Sellstedt and Richau, 2013; Wen et al ., 2022; Yu et al ., 2022).…”

The rhizosphere microbiota plays crucial roles in biogeochemical cycling and primary production. However, there is a lack of research exploring the complex relationships between microbiota and their functional traits in pepper rhizospheres, as well as their impact on nutrient cycling processes. Here, we investigated the effects of pepper species on the rhizomicrobiota and functional genes (C/N/P/S) on nutrient absorptions and accumulations in pepper organs. The results revealed that Pepper YZ/BE had higher N content in all compartments, which could be attributed to the presence of enriched N-metabolic microbes (Gaiellales/Leifsonia) and higher expression of N availability-promoting genes (ureC/amoA2/nxrA/napA) in rhizospheres. Additionally, we utilized co-occurrence network analysis and partial least squares path modeling (PLS-PM) to understand the interactions among the variables. The bacterial network exhibited more associations than the fungal network, and the abundance of certain modules positively correlated with the expression of CNPS genes, which thus significantly influenced pepper nutrient content. The PLS-PM analysis demonstrated that taxa abundance in network modules, functional genes, and rhizospheric soil properties collectively explained 92% of the variance in pepper nutrient content. Overall, this study provides valuable experimental and theoretical insights into the effects of rhizosphere microorganisms and CNPS genes on the nutritional traits of Capsicum.

“…The abundance of Actinobacteria and Firmicutes was positively correlated with soil SOM values, which is consistent with experimental results on the effect of bioorganic fertilizer on banana yield and quality ( Li Z. et al, 2021 ). Additionally, Song Y. et al (2022) reported the close relationship between Acidobacteria and Proteobacteria with crucial soil nutrients like available potassium (AK), available phosphorus (AP), and ammonium nitrogen (AN).…”

IntroductionEuryales Semen, a medicinal herb widely utilized in Asia, faces a critical constraint in its production, primarily attributed to fertilizer utilization. Understanding the impact of different fertilization schemes on Euryales Semen (ES) planting and exploring the supporting mechanism are crucial for achieving high yield and sustainable development of the ES planting industry.MethodsIn this study, a field plot experiment was conducted to evaluate the effects of four different fertilization treatments on the yield and quality of ES using morphological characteristics and metabolomic changes. These treatments included a control group and three groups with different organic fertilizer to chemical fertilizer ratios (3:7, 5:5, and 7:3). The results of this study revealed the mechanisms underlying the effect of the different treatments on the yield and quality of Euryales Semen. These insights were achieved through analyses of soil physicochemical properties, soil enzyme activity, and soil microbial structure.ResultsWe found that the quality and yield of ES were the best at a ratio of organic fertilizer to chemical fertilizer of 7:3. The optimality of this treatment was reflected in the yield, soil available nitrogen, soil available phosphorus, and soil enzyme activity of ES. This ratio also increased soil microbial diversity, resulting in an increase and decrease in Proteobacteria and Firmicutes abundances, respectively. In addition, linear discriminant analysis showed that Chloroflexi, Gammaproteobacteria, and Hypocreales-incertae-sedis were significantly enriched in the ratio of organic fertilizer to chemical fertilizer of 7:3. Variance partitioning analysis showed that the soil properties, enzyme activities, and their interactions cumulatively can explain 90.80% of the differences in Euryales Semen yield and metabolome. In general, blending organic and chemical fertilizers at a 7:3 ratio can enhance soil fertility, boost Euryales Semen yield and quality, and bring forth conditions that are agriculturally beneficial to microbial (bacteria and fungi) dynamics.DiscussionThis study initially revealed the scientific connotation of the effects of different fertilization patterns on the planting of Euryales Semen and laid a theoretical foundation for the study of green planting patterns of Euryales Semen with high quality and yield.

Organic fertilizer is utilized to improve the organic carbon levels in arable soils, which is helpful for soil quality improvement and crop yield increase. However, the after-effect of organic fertilizer varies among regions with different temperature and precipitation conditions, and the extent of the impact remains unknown. This study aimed to investigate the impact of varying temperature and rainfall conditions on the accumulation of soil organic carbon after organic fertilizer application. A meta-analysis of 168 peer-reviewed studies published between 2005 and 2022 involving a total of 464 trials was conducted. The following was discovered: (1) In the major grain-producing areas of China, there was a significant positive correlation (p < 0.01) between latitude and soil organic carbon content. Meanwhile, temperature and precipitation had a significant negative correlation (p < 0.01) with soil organic carbon content. (2) The increase in temperature inhibited the increase in soil organic carbon storage. The improvement effect of organic fertilizer application in the low-temperature areas was significantly increased by 60.93% compared with the mid-temperature areas, and by 69.85% compared with the high-temperature areas. The average annual precipitation affected the after-effect of organic fertilizer as follows: 400–800 mm > 400 mm > more than 800 mm. (3) The influence of climatic conditions on the after-effect of organic fertilizer was more significant depending on the specific tillage practice. To increase organic fertilizer use efficiency and eliminate greenhouse gas emissions, liquid organic fertilizers with abundant trace nutrients and amino acids, which take advantage of releasing nutrients more swiftly and have a better fertilization effect, could be an alternative to traditional organic fertilizers.
