“…No special agronomic practices have been adopted at the flue-cured tobacco-planting sites sampled in this study. The amount of fertilizers applied often differs because the basic fertility of the soil and the demand of crops are usually considered when applying fertilizer in the field 21,25,27 . In addition, although the irrigation method used can affect the quality of flue-cured tobacco, the methods are not determined by the cultivars but by the sources of available water 23 .…”

Flue-cured tobacco (Nicotiana tabacum L.) is a major cash crop in Yunnan, China, and the yield, chemical components, and their proportions decide the quality of tobacco leaves. To understand the effects of environmental factors (soil and climatic factors) on the yield and quality of flue-cured tobacco and determine the main regulating factors, we selected three flue-cured tobacco cultivars [K326, Yunyan87 (Yun87), and Honghuadajinyuan (Hongda)] grown in the Honghe Tobacco Zone. Indices related to yield and economic traits, chemical component properties, soil physical and chemical properties, and climatic factors at different planting sites, were evaluated. We used variance analysis, correlation analysis, and redundancy analysis (RDA) in this study. The results showed that the yield and chemical component properties of flue-cured tobacco, except for the number of left leaves and plant total sugar (PTS) content, were significantly correlated with climatic factors. Particularly, the yield increased in drier and sunnier weather. In terms of the carbon supply capacity, PTS, petroleum ether (PPE), and starch contents (PS) were higher under high-altitude and high-latitude climatic conditions, whereas for the nitrogen supply capacity, plant nitrogen (PTN) and nicotine (PN) contents improved under low-altitude and low-latitude climatic conditions. PTS, reducing sugar (PRS), potassium (PTK), chlorine (PCL), and PPE contents were negatively related to soil clay content, soil pH, and soil organic matter, whereas PRS and PTK contents were positively correlated with alkali-hydrolyzed nitrogen (AN). According to RDA, the soil clay, AN, available phosphorus (AP), and soil chlorine content (SCL) strongly affected the quality of flue-cured tobacco. The quality of the K326 and Yun87 cultivars was mostly influenced by moisture, whereas the quality of the Hongda cultivar was mostly affected by temperature. In conclusion, compared with soil properties, climatic factors more significantly affect the yield and quality of Honghe flue-cured tobacco leaves.

“…Ample evidence has accumulated in recent years that the quantity and quality of soil organic matter can significantly affect the composition of soil microbial community [28][29][30] , which is often represented by the phenomenon that soils with high organic matter content tend to have higher microbial community diversity 31,32 . In our study, both the Chao 1 index and the Shannon index in the M treatment were lower than that in the NM treatment Paired T-test DF = 2, t = 0.27 p = 0.8140 DF = 2, t = −2.08 p = 0.1732 DF = 2, t = −8.12 p = 0.0148 DF = 2, t = −2.77 p = 0.1096 DF = 2, t = −3.32 p = 0.0800 DF = 2, t = 0.65 p = 0.5799 DF = 2, t = 0.80 p = 0.5083 DF = 2, t = −1.73 p = 0.2254 DF = 2, t = −1.30 p = 0.3227 www.nature.com/scientificreports www.nature.com/scientificreports/ ( Fig.…”

Raising rice seedlings in flat trays has become the main method for mechanized transplanting of rice in China. However, seedling blocks raised by this method were easily cracked in practice, and this problem can be solved by padding a thin ramie fiber nonwoven film on the bottom surface of seedling tray. This study was conducted to determine the effects of this film on root-zone environment of rice seedlings. The results showed that on the 10 th day after sowing, the soil inorganic nitrogen, especially nitrate nitrogen, content in the root-zone of the film treatment were considerably higher than in the no-film treatment, in contrast, the soil organic matter content was lower in the film treatment, and by the 20 th day, the gap between treatments was enlarged. After applying the film, the Chao 1 index and Shannon index values for the soil bacterial community diversity decreased, and the rice seedlings were shorter, had higher root/shoot ratios, lower nitrate contents, and higher soluble sugar contents. We conclude that application of the ramie fiber nonwoven film resulted in substantial changes in the soil nutrient and bacterial community in root-zone in a short time, which significantly impacted the growth and development of rice seedlings.Rice is a major staple food for about 50% of the world's population 1 . Rice fields account for more than 12% of global cropland area 2 . China is one of the major rice-producing countries in the world with a rice cultivation area of about 30 million hectares, accounting for approximately 18.6% of the world's rice field area 3 . With an increasingly scarce rural labor force, raising rice seedlings in flat trays followed by mechanical transplantation has become a prevalent cultivation method to replace hand transplanting in Chinese rice production 4 . However, this method has a serious defect in practice, as the root system of the seedlings was often not sufficiently intertwined by the optimum transplanting date (20-25 days after sowing). Insufficient rooting in the seedling block means the rice seedling blocks easily crack (Fig. 1c), so the efficiency of mechanical transplanting was seriously decreased 5 .In recent years, An innovative ramie fiber nonwoven film (Fig. 1a) was developed to solve this problem 6 . This film was made of waste fiber from the ramie spinning industry and modified starch, and was constructed using a dry-laid, nonwoven process. Unlike the traditional agricultural nonwoven films that are usually used as mulching materials to cover soil, this film was used to pad the bottom surface of a seedling tray, and was covered by soil (Fig. 1b). The film was quite thin (only about 0.15-0.25 mm); however, previous research 7,8 showed that the efficiency of machine transplanting was significantly improved by using this film, as it promoted the growth of rice seedling roots and helped to form a strong, not easily broken seedling block (Fig. 1d). Moreover, it can significantly improve rice seedling quality, speed up the emergence of new tillers after transplanting, and ...

“…The latest advances in the soil metagenomics emerge as an extraordinary area of research because of the assignment of understanding the associated microorganisms in development and plant growth [75,76]. Likewise, restoration of the microbial population was determined to improve grain yield as well as soil health [77]. Metagenomics can predict the soil microbes' structure and the impact on microbial groups of connected niches [9,35].…”

The better strategies to examine RNA or DNA from soil allow us to understand the microbial diversity and features in the soil, which are challenging to identify by typical culture techniques. In this direction, the literature on soil metagenomics and its usefulness is ever-increasing and so as its implementation experiences. Omics techniques are going to assist the metagenomics in achieving agricultural sustainability. In doing so, essential understanding on the reference soil would serve to help upcoming soil survey initiatives, lessening bias and raising objectivity. Although the interpretation of limited details has influenced microbial ecologists, the scope of methodological bias remains unfamiliar. A detailed catalog of functional genes and soil microorganisms does not yet exist for any soil. Overall, this chapter provides thoughts related to the soil metagenomics, its importance, and conventional methods of analysis, along with prospects and challenges of soil metagenomics.
