Background The bacterial communities is complex and different in various agricultural ecosystem. In this study, high-throughput Illumina MiSeq sequencing was conducted to assess the differences in soil bacterial communities between organic farming and conventional farming modes. Results A total of 3, 919 operational taxonomic units were identified and classified as 26 phyla, 42 classes, 78 orders, 120 families, 281 genera. The dominant genera were Lysobacter , Pseudomonas , Massilia , Pseudarthrobacter , Ferruginibacter , Flavobacterium , Flavisolibacter , Brevundimonas , Haliangium and Sphingomonas . Analysis of soil bacterial diversity showed that the soil under the organic farming had a greater bacterial diversity than that under the conventional farming. Linear discriminant analysis effect size analysis showed that the major bacterial groups identified in the soil sample CK1 (2015.4) and CK6 (2017.10) under conventional farming mode were largely different from those in the soil sample O6 (2017.10) under organic farming mode. Redundancy analysis demonstrated that available nitrogen was the most important factor regulating bacterial composition under the organic farming mode, followed by soil rapidly available phosphorous and potassium. Massilia , Pseudomonas , Lysobacter and Pseudarthrobacter abundances showed a strong positive correlation with the content of available nitrogen. Conclusions Organic farming could improve soil organic matter, available nitrogen, rapidly available phosphorus and retard soil acidification. This modification of soil can directly or indirectly relate to the bacterial communities in soil. The shifts of bacterial communities were complicated and dynamic with respect to all sorts of the measures of cultivation and management under organic farming mode.

“…The engineered microbial system is the hope to expand their application as beneficial communities are used in agriculture, and thus enhance crop productivity and environmental sustainability. Though they can be superior in performance to the natural microbial inoculants, their successful existence in the soil matters [ 93 , 94 ]. There is an ongoing controversy in the application of genetically engineered microbial inoculants in the field.…”

: Enchanced agricultural production is essential for increasing demand of growing world population. At the same time, to combat the adverse effects caused by conventional agriculture practices to the environment along with the impact to human health and food security, a sustainable and healthy agricultural production needs to be practiced using beneficial microorganisms for enchanced yield. It is quite challenging because these microorganisms have are rich biosynthetic repositories to produce biomolecuels of interest; however, the intensive research in allied sectors and emerging genetic tools for improved microbial consortia are welcoming approaches that are helpful to farmers and agriculturists to meet the ever-increasing demand of sustainable food production. An important advancement is improved strain developments via genetically engineered microbial systems (GEMS) as well as genetically modified microorganisms (GMOs) possessing known and upgraded functional characteristics to promote sustainable agriculture and food security. With the development of novel technologies such as DNA automated synthesis, sequencing and influential computational tools, molecular biology has entered the systems biology and synthetic biology era. More recently, CRISPR/Cas has been engineered to be an important tool in genetic engineering for various applications in the agri sector. The research in sustainable agriculture is progressing tremendously through GMOs/GEMS for their potential use in biofertilizers and as biopesticides. In this review, we discuss about beneficial effects of enginnered microorganisms through integrated sustainable agriculture production practices to improve the soil microbial health in order to increase crop productivity.

“…Indeed, sustainable agriculture is part of a sustainable land development strategy that emphasizes the long-term production of food and cash crops, with minimal environmental effects and improved soil health [12]. Sustainable agriculture uses techniques that have no or minimal impacts, especially soil environments, such as soil flora and fauna [13]. These techniques include soil microbiota management [14], zero tillage [15], prevention from soil erosion [16], fallowing the soils, and cover cropping, as well as inter-cropping [17,18].…”

A detailed field experiment was carried out to study the effect of conventional and zero tillage and legume intercrops on soil health indicators and cotton productivity and also yield components of leguminous crops at the Research Farm, MNS-University of Agriculture, Multan, Pakistan. The field experiment was comprised of four legume intercrops (no intercrops (sole cotton), mung bean, mash bean, and soybean) and two tillage systems (three years zero tillage (ZT) and long-term conventional tillage (CT)). The CT showed the highest plant height (121 cm), total bolls per plant (22.9 bolls), boll weight (2.74 g) and seed yield (2031 kg ha−1) of the cotton crop, as compared to ZT. The highest leaf transpiration rate (9.28 mmol H2O m−2 s−1), net leaf photosynthetic rate (27.17 µmol m−2 s−1), stomatal conductance (0.493 mmol m−2 s−1), chlorophyll content (62.3 SPAD value), plant height (123 cm), total bolls per plant (24.4), boll weight (2.83 g), and seed yield (2090 kg ha−1) of cotton crop were recorded when it was grown as a sole crop, as compared to legume intercrops. However, soil organic matter (0.77%), phosphorus (8.08 mg kg−1), potassium (253 mg kg−1), and microbial population (7.26 × 106 Cfu) were higher in ZT than in CT. Mung bean showed a maximum number of pods (32), seed yield (173 kg ha−1), biomass (950 kg ha−1), and harvest index (19.0%), when intercropped with cotton. The highest land equivalent ratio and area time equivalent ratio were recorded in mung bean and cotton intercropping, grown under a CT system. Furthermore, the maximum benefit-cost ratio was recorded in mung bean and cotton intercropping, over sole cotton cropping under CT (1.75) and ZT (1.67) systems. The ZT and intercropping of leguminous crops with cotton might be a promising option for increasing the seed cotton yield, seed yield of leguminous crops, system profitability, and sustainability of soil health.
