“…Maize secretes root exudates that improve soybean nodule formation and nitrogen fixation, while the fixed nitrogen from soybeans is transferred to maize through root exudates or mycorrhizal fungi (Li et al, 2016 ; Thilakarathna et al, 2016 ). Jessica et al found that the soil microbial diversity of 1-year melon-cowpea intercropping system decreased, which was consistent with the results of this experiment (Cuartero et al, 2022 ). Studies have also shown that intercropping reduced the biomass of bacteria and fungi in the rhizosphere of rape (Hartmann et al, 2015 ; Lupatini et al, 2017 ; Sun et al, 2021 ).…”

Flowering stage of soybean is an important agronomic trait, which is important for soybean yield, quality and adaptability, and is the external expression of integrating external environmental factors and endogenous signals of the plant itself. Cropping system can change soil properties and fertility, which in turn determine plant growth and yield. The microbial community is the key regulator of plant health and production performance. Currently, there is limited understanding of the effects of cropping systems on microbial community composition, ecological processes controlling community assembly in different soil-plant continuum compartments of soybean. Here, we hope to clarify the structure and assembly process of different soybean compartments bacterial community at flowering stage through our work. The results showed that intercropping decreased the species diversity of rhizosphere and phyllosphere, and phylloaphere microbes mainly came from rhizosphere. FAPROTAX function prediction showed that indicator species sensitive to intercropping and crop rotation were involved in nitrogen/phosphorus cycle and degradation process, respectively. In addition, compared to the continuous cropping, intercropping increased the stochastic assembly processes of bacterial communities in plant-associated compartments, while crop rotation increased the complexity and stability of the rhizosphere network and the deterministic assembly process. Our study highlights the importance of intercropping and crop rotation, as well as rhizosphere and phyllosphere compartments for future crop management and sustainable agricultural regulation of crop microbial communities.

“…A previous study showed that the reduction in CO 2 emissions was mainly due to the changes in bacterial community composition (Wang et al, 2020). Network analysis showed that the Rs rate mainly related to the phylum Proteobacteria and Chloroflexi at the PF stage and the phylum Bacteroidota and Chloroflexi at the MS stage, which were the most abundant bacterial phyla in soil environments (Guo et al, 2021;Cuartero et al, 2022). Furthermore, the relative abundance of Proteobacteria decreased with the reduction in the CAT activity, thereby mitigating the Rs rate at the PF stage.…”

“…Both cropping patterns and N management influenced the bacterial beta diversity of pea strips, but only the latter affected maize strips. The major reason was that the intercropping pattern changed the soil microenvironment and nutrient content, thus affecting the growth of the soil microorganisms (Cuartero et al, 2022). Moreover, fertilization management regimes could affect microbial beta diversity by altering soil properties, including soil pH, bulk density, electrical conductivity, water content, total nitrogen, organic carbon, NO N 3 --, and available potassium (Ren et al, 2021).…”

Strategies to reduce carbon emissions have been a hotspot in sustainable agriculture production. The delayed N fertilizer application had the potential to reduce carbon emissions in pea (Pisum sativum L.)/maize (Zea mays L.) intercropping, but its microbial mechanism remains unclear. In this study, we investigated the effects of delayed N fertilizer application on CO2 emissions and soil microbial diversity in pea/maize intercropping. The soil respiration (Rs) rates of intercropped pea and intercropped maize were decreased by 24.7% and 25.0% with delayed application of N fertilizer, respectively. The total carbon emissions (TCE) of the pea/maize intercropping system were also decreased by 21.1% compared with that of the traditional N fertilizer. Proteobacteria, Bacteroidota, and Chloroflexi were dominant bacteria in pea and maize strips. Heatmap analysis showed that the soil catalase activity at the pea flowering stage and the soil ΝΗ4+-Ν at the maize silking stage contributed more to the variations of bacterial relative abundances than other soil properties. Network analysis demonstrated that Rs was positively related to the relative abundance of Proteobacteria and Bacteroidota, while negatively related to the relative abundance of Chloroflexi in the pea/maize intercropping system. Overall, our results suggested that the delayed application of N fertilizer combined with the pea/maize intercropping system altered soil bacterial community diversity, thereby providing novel insights into connections between soil microorganisms and agricultural carbon emissions.

“…The intercropping system, i.e., cultivating two or more crop species simultaneously in the same field area [38], has been proposed as a sustainable management practice that enhances soil productivity as well as encouraging the more efficient use of resources such as water or nutrients [39][40][41] and promoting bacterial community structure changes [42]. In addition, several studies have demonstrated that intercropping significantly promotes agroecosystem services [43][44][45][46].…”

Crop Diversification Effects on Soil Aggregation and Aggregate-Associated Carbon and Nitrogen in Short-Term Rainfed Olive Groves under Semiarid Mediterranean Conditions

Soil particle aggregation and their associated carbon (C) and nitrogen (N) content can provide valuable diagnostic indicators of changes in soil properties in response to the implementation of different agricultural management practices. In this sense, there is limited knowledge regarding the impact of intercropping on soil organic carbon (SOC) and total nitrogen (TN) pools in aggregates. This study aimed to evaluate the short-term effect (4 years) of three crop diversifications in rainfed olive orchards on soil aggregation, SOC and TN concentration and SOC stocks (SOC-S) under semi-arid Mediterranean conditions. Olive orchards were diversified with Crocus sativus (D-S), Vicia sativa and Avena sativa in rotation (D-O) and Lavandula x intermedia (D-L) and compared with monocropping system (CT). Soil samples were collected at two depths (0–10 and 10–30 cm) and analysed for soil aggregate mass, SOC and TN content in aggregate-size fractions obtained by the wet-sieving method. Changes caused by crop diversifications on SOC-S were also determined. Overall, after 4 years, a reduction in aggregation values was observed. However, D-S increased the macroaggregates (>250 μm) percentage, Mean Weigh Diameter values, and Geometric Mean Value in the 0–10 cm. Across treatments, aggregate-associated C in 0–10 cm was higher in the D-S treatment, while in the 10–30 cm soil layer, the greatest values were found in CT. Regarding the SOC-S, after 4 years, significant losses were recorded under CT management in 0–10 cm (−1.21 Mg ha−1) and 10–30 cm (−0.84 Mg ha−1), while D-O and D-L showed similar values to those obtained at the beginning of the study. The highest increases in SOC-S were found in D-S, with an increase of 5.88% in the 0–10 cm and 14.47% in the 10–30 cm. Our results showed the high potential of the diversified cropping system to increase soil stability and SOC sequestration.
