“…The higher P applied via fertilizer in the maize growth period compared with that of soybean resulted in higher AP content in MW rotation. Fertilizer application rate is highly dependent on crop type, thus MW rotation increased AP content (Table 1), the relative abundance of Bacillus genus was negatively related to AP in the present study (Figure 7B), which was in accordance with the previous study (Huang et al, 2020). The lower AP content stimulated Bacillus to solubilize non-available P into orthophosphate to provide AP for crops (Tye et al, 2002).…”

Including legumes in the cereal cropping could improve the crop yield and the uptake of nitrogen (N) and phosphorus (P) of subsequent cereals. The effects of legume-cereal crop rotations on the soil microbial community have been studied in recent years, the impact on soil functional genes especially involved in P cycling is raising great concerns. The metagenomic approach was used to investigate the impacts of crop rotation managements of soybean-wheat (SW) and maize-wheat (MW) lasting 2 and 7years on soil microbial communities and genes involved in P transformation in a field experiment. Results indicated that SW rotation increased the relative abundances of Firmicutes and Bacteroidetes, reduced Actinobacteria, Verrucomicrobia, and Chloroflexi compared to MW rotation. gcd, phoR, phoD, and ppx predominated in genes involved in P transformation in both rotations. Genes of gcd, ppa, and ugpABCE showed higher abundances in SW rotation than in MW rotation, whereas gadAC and pstS showed less abundances. Proteobacteria, Acidobacteria, and Gemmatimonadetes played predominant roles in microbial P cycling. Our study provides a novel insight into crop P, which requires strategy and help to understand the mechanism of improving crop nutrient uptake and productivity in different rotations.

“…All these techniques warrant different degrees of accuracy and relationship with soil biogeochemical processes. Meta-omic approaches were able to decipher the phenomenon at the level of genes responsible for degradation of target pesticides [ 207 , 208 , 209 ] which could further give clues to expedite the process of residue clean-up from agricultural lands.…”

Agriculture is a multifarious interface between plants and associated microorganisms. In contemporary agriculture, emphasis is being given to environmentally friendly approaches, particularly in developing countries, to enhance sustainability of the system with the least negative effects on produce quality and quantity. Modern agricultural practices such as extensive tillage, the use of harmful agrochemicals, mono-cropping, etc. have been found to influence soil microbial community structure and soil sustainability. On the other hand, the question of feeding the ever-growing global population while ensuring system sustainability largely remains unanswered. Agriculturally important microorganisms are envisaged to play important roles in various measures to raise a healthy and remunerative crop, including integrated nutrient management, as well as disease and pest management to cut down agrochemicals without compromising the agricultural production. These beneficial microorganisms seem to have every potential to provide an alternative opportunity to overcome the ill effects of various components of traditional agriculture being practiced by and large. Despite an increased awareness of the importance of organically produced food, farmers in developing countries still tend to apply inorganic chemical fertilizers and toxic chemical pesticides beyond the recommended doses. Nutrient uptake enhancement, biocontrol of pests and diseases using microbial inoculants may replace/reduce agrochemicals in agricultural production system. The present review aims to examine and discuss the shift in microbial population structure due to current agricultural practices and focuses on the development of a sustainable agricultural system employing the tremendous untapped potential of the microbial world.

“…A completely randomized block design with three different sowing techniques and a control was used in field experiment during the winter wheat season. The four sowing treatments were: (a) conventional drill sowing technique (CD), (b) film-mulched ridge sowing technique (FMR), (c) wide ridge and narrow furrow sowing technique (WR&NF), and a control (CK) according to the description of (Huang, Han, Yang, Chen, & Rengel, 2020). Each treatment was replicated three times and the plot size was 1,334 m 2 .…”

The activities of soil resident enzymes and fungal communities are critical for soil health and ecosystem functionality. However, their dynamics in response to variations in sowing techniques are poorly understood. This study aimed to investigate the effects of wide-ridge and narrow-furrow (WR&NF), film-mulching ridge (FMR), and conventional drilling (CD) practices on the activities of soil-residing enzymes and fungal communities in a dryland wheat field on the Loess Plateau. Photometrically, unbuffered, and colorimetric methods were employed to determine the activities of alkaline phosphatases, urease, and sucrase enzymes, respectively. Soil fungal diversity and community composition was measured via the Illumina Miseq 2500 sequencing method. The results revealed that WR&NF and FMR practices significantly enhanced the soil activities of alkaline phosphatases, urease, and sucrase, while improving soil fungal communities including Chytridiomycota phylum and Phoma (Ascomycota), Olpidium (Chytridiomycota), and Trichosporon (Basidiomycota) genera. Both the enzymatic activities and fungal community compositions of the soils under study varied from rhizosphere to non-rhizosphere, as well as at different soil depths. Remarkably, several soil fungal genera, including Cystofilobasidium (Basidiomycota), Triparticalcar (Chytridiomycota), and Guehomyces (Basidiomycota) were more abundant in the subsoil than topsoil. In general, we observed that ridge-furrow and film-mulching practices enhanced the enzyme activities and improved fungal communities of soils. Therefore, the wide-ridge and narrow-furrow sowing technique is recommended as an environmentally compatible practice to benefit the arid wheat (Triticum aestivum L.
