Abstract Aims Maize/soybean intercropping has many advantages in soil nitrogen (N) use compared with monocultures. However, whether fungi increase the mineralization of organic N remains unknown. We hypothesized that fungal-mediated increases mineral N. Methods Soil was sampled a 13-year field experiment monocultured maize, soybean and maize/soybean without input (N0) 180 kg ha− 1 (N180). The net mineralization, mineralization-related enzymes (urease protease) fungal communities were analyzed to show occurred role mineralization. Results Based on long-term experiment, redundancy analysis showed chemical properties enzyme activities explained 67.92% total variation communities. Intercropping increased content by 1.6 times mainly due ammonium content, richness diversity not affected under N0. There is no correlation between relative abundance different crop systems, but Glomeromycota N180 (p = 0.04). Conclusion affecting input. potential regardless systems. This study provides evidence driven further research needed explore microbial mechanism

Abstract Climate‐smart agriculture (CSA) supports the sustainability of crop production and food security, benefiting soil carbon storage. Despite critical importance microorganisms in cycle, systematic investigations on influence CSA microbial necromass its driving factors are still limited. We evaluated 472 observations from 73 peer‐reviewed articles to show that, compared conventional practice, generally increased concentrations by 18.24%. These benefits carbon, as assessed amino sugar biomarkers, complex influenced a variety soil, climatic, spatial, biological factors. Changes living biomass most significant predictor total, fungal, bacterial affected CSA; 61.9%–67.3% paired observations, measures simultaneously carbon. Land restoration nutrient management therein largely promoted storage, while cover has minor effect. Additionally, effects were directly elevation mean annual temperature, indirectly texture initial organic content. In optimal scenario, potential global accrual rate through is approximately 980 Mt C year −1 , assuming amendment included following conservation tillage appropriate land restoration. conclusion, our study suggests that increasing provides vital way mitigating loss. This emphasizes invisible yet anabolic activity dynamics.

With mounting demand for high-quality agricultural products and the relentless exploitation of arable land resources, finding sustainable ways to safely cultivate food crops is becoming ever more important. Here, we investigated effects integrated cropping technique “straw return + intercropping” on soil aggregates as well microbial biomass carbon (MBC) content, enzyme activities diversity in soils maize soybean crops. Our results show that comparison straw removal monoculture, intercropping increase rhizosphere’s MBC content (59.10%) soil, along with urease (47.82%), sucrase (57.14%), catalase (16.14%) acid phosphatase (40.66%) under soybean. Under same treatment, yield when intercropped surpassed grown equivalent ratio treatment being highest. Overall, beneficial healthy development agriculture black region northeast China, especially combined fields.

Diversified cropping systems and fertilization strategies were proposed to enhance the abundance diversity of soil microbiome, thereby stabilizing their beneficial services for maintaining fertility supporting plant growth. Here, we assessed across three different long-term field experiments in Europe (Netherlands, Belgium, Northern Germany) whether diversified also affect functional gene abundance. Soil DNA was analyzed by quantitative PCR quantifying bacteria, archaea fungi as well genes related nitrogen (N) transformations; including bacterial archaeal nitrification (amoA-bac,arch), steps denitrification process (nirK, nirS nosZ-cladeI,II) N2 assimilation (nifH), respectively. Crop diversification generally enhanced total carbon (C), N microbial abundance, but with variation between sites. Overall effects on much stronger than fungi. The legume-based showed great potential not only stimulating growth N-fixing microorganisms boosting downstream potentials cycling. sorghum-based intercropping system suppressed ammonia oxidizing prokaryotes. reduced nitrifiers denitrifiers except ammonia-oxidizing while application synthetic inhibitor DMPP combined mineral both bacteria archaea. In conclusion, this study demonstrates a strong impact agricultural practices microbiome mediating transformations.
