“…Continuous monocultures reduce soil microbial biodiversity and alter the microbial community structure, which decreases its buffering capability to tolerate biotic and abiotic stress, thus increasing the incidence of disease and subsequently affecting plant health (Wang et al, 2011;Mo et al, 2016;Xiong et al, 2016). Continuous cropping could reduce the quantity of bacteria in the soil and increase the relative proportion of fungi.…”

The predominant cropping system and management practices play an important role in soil physico-chemical properties and microbiome composition and diversity. This study analyzed the changes in soil fertility and the microbial community in four soybean-based cropping systems over 12 years. Amplification subsequencing techniques were used to compare soil community structures among the systems and identify significant positive and negative fertility factors. Soybean cropping favored the accumulation of OM and the available N, K DTPA Fe, Mn, Zn and Cu contents in soil but not fixed available P. The WS and CS cropping systems were conducive to the fixed available P, but they consumed OM, DTPA K, and Zn. The SC exhibited the lowest soil bacterial and archaeal abundance and diversity but high fungal abundance and diversity. The dominant Proteobacteria in the SC were significantly positively correlated with soil DTPA Fe and Mn. The dominant Actinobacteria were positively correlated with available P, DTPA Cu and Mn. The FS cropping system contained 764 unique bacterial species, 724 unique fungal species and the highest relative abundance of Protista. The FS had high microbial diversity, with high relative abundances of Bacteroidetes and Zygomycota and a significantly lower relative abundance of Actinobacteria. The Bacteroidetes were significantly correlated with available N, OM and DTPA Fe and negatively correlated with available P and DTPA Cu. Zygomycota was negatively correlated with available P and DTPA Cu. In the CS and WS, the soil bacterial abundance and diversity were moderate. The dominant Acidobacteria was significantly negatively correlated with soil DTPA, Fe and Mn. The CS exhibited the lowest fungal abundance and diversity. Furthermore, the relative abundance of Ascomycota was significantly improved in the WS and significantly positively correlated with available P and DTPA Cu. Decreases in the available P, K, DTPA Cu, and Mn of Vertisols greatly affect microbial community structure, and these nutrients regulate bacterial and fungal abundance and diversity. Compared to the SC, the FS, WS, and CS had more balanced soil fertility and microbial stability, but diverse cropping systems are most conducive to soil productivity. These findings are of great relevance for protecting the ecological environment.

“…Continuous cropping may reduce the bacterial population in the soil while increasing the relative proportion of fungi. This may decrease the buffering capability to biotic and abiotic stress, increasing the disease pressure ( Mo et al., 2016 ; Wang et al., 2011 ; Xiong et al., 2016 ). Cropping systems that leave crop residues behind may increase SOM and microbial activities, as well as reducing soil erosion.…”

Soil microbial communities play a crucial role in soil fertility, sustainability, and plant health. However, intensive agriculture with increasing chemical inputs and changing environments have influenced native soil microbial communities. Approaches have been developed to study the structure, diversity, and activity of soil microbes to better understand the biology and plant-microbe interactions in soils. Unfortunately, a good understanding of soil microbial community remains a challenge due to the complexity of community composition, interactions of the soil environment, and limitations of technologies, especially related to the functionality of some taxa rarely detected using conventional techniques. Culture-based methods have been shown unable and sometimes are biased for assessing soil microbial communities. To gain further knowledge, culture-independent methods relying on direct analysis of nucleic acids, proteins, and lipids are worth exploring. In recent years, metagenomics, metaproteomics, metatranscriptomics, and proteogenomics have been increasingly used in studying microbial ecology. In this review, we examined the importance of microbial community to soil quality, the mystery of rhizosphere and plant-microbe interactions, and the biodiversity and multi-trophic interactions that influence the soil structure and functionality. The impact of the cropping system and climate change on the soil microbial community was also explored. Importantly, progresses in molecular biology, especially in the development of high-throughput biotechnological tools, were extensively assessed for potential uses to decipher the diversity and dynamics of soil microbial communities, with the highlighted advantages/limitations.

“…The rice and wheat growing system (RWGS) has been blamed for depleting groundwater, degrading soil structure, increasing salinity and sodicity (Bhattacharyya et al, 2015), and also for causing rising multiple micronutrient deficiencies (Biswas & Tewatia, 1991), increasing greenhouse gases and problems due to large‐scale burning of rice straw (Jat, Singh, & Gerard, 2014) ‐ the latter resulting in a decline in soil quality. Mo, Qiu, He, Wu, & Zhou (2016) also suggested that continuous monoculture exerts adverse impacts on soil microbial diversity and plant health owing to changing microbial community structure. Similarly, continuous potato cropping over the years has caused a shift in soil microflora from bacteria to fungi that has exerted adverse effects on microbial, enzymatic, and nutrient availability (Ma, Zhang, Du, & Song, 2010).…”

In the last two decades, the productivity of the rice–wheat growing system (RWGS) in the upper Indo‐Gangetic Plains of India has come to a plateau, and, as a result, farmers are now shifting to other crop growing systems (cropping sysytems) to achieve a higher net productivity. Inclusion of other cropping systems in place of the rice–wheat system affects overall crop productivity; however, there is dearth of information with respect to nutrient index (NI), microbial diversity, and soil quality. This study was carried out to assess how NI, microbial diversity, and soil quality changed after replacement of rice–wheat by a vegetable growing system (VGS), pulse growing system (PGS), potato growing system (PoGS), and a mustard growing system (MGS). An analysis of 307 soil samples from these crop growing systems revealed a soil pH range of 6.58–8.87 with 75.3% soils falling within the low category of mineralized N, and low NI (<1.67). The highest NI, enzymatic activity, and microbial diversity was recorded under PGS, which restored 34.2, 24.1, and 10.2% greater soil organic carbon (SOC) than other systems, and had a better carbon substrate oxidation rateand mineralized N than PoGS. The diversity indices peaked under PGS followed by VGS due to greater SOC, mineralized N, higher microbial counts, and more soil enzymes. Among the different crop growing systems the soil quality index (SQI) ranged from 0.647 (for PoGS) to 0.783 (for VGS) . The silt content, SOC, Zn, TN, acid phosphatase activity, available P, and total culturable fungi were the key soil indicators across all the crop growing systems. SOC is the most important and viable indicator for all the crop growing systems that affected microbial dynamics and soil quality. The greater SQI under VGS was due to the addition of organic manure and augmented SOC, P, and Zn availability. In contrast, the highest microbial and enzymatic activities, and functional diversity was recorded under PGS mainly due to greater edaphic variables. It is concluded that the pulse growing system (PGS) is the best for maintaining higher NI, and improving microbial and functional diversity.
