Past research has highlighted that a diverse soil microbial community and variation in plant traits for resource acquisition can mitigate the negative impacts of climate change factors on crop productivity. This study investigates the effects of two major environmental stressors—drought and salinity stress, on plant productivity, biomass allocation, and root and leaf trait responses under distinct soil microbial diversities. Our results showed that salinity stress had stronger negative impacts on plant productivity than drought stress. Shoot biomass decreased by 30% and 32.5% under drought and salinity stress, respectively, whereas the root biomass decreased by 32% only under salinity stress. Soil microbial diversity did not affect plant productivity. Next, root traits were mainly impacted by drought and salinity stress, whereas leaf traits were impacted by both environmental stresses and soil microbial diversity. Specific root length and specific root area decreased under drought, and root tissue density was minimal under salinity stress. Root traits were not affected by soil microbial communities. In contrast, the leaf nitrogen content increased, whereas pheophytin content (a breakdown product of chlorophyll) decreased when plants were grown in diverse microbial communities under environmental stresses, especially drought. These results highlight the importance of soil microbial diversity in impacting plant traits in response to environmental stresses. We showed that the soil microbial diversity influences both aboveground and belowground plant traits, indicating the need for better management practices to conserve and promote soil microbial diversity.</p>","PeriodicalId":100834,"journal":{"name":"Journal of Sustainable Agriculture and Environment","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/sae2.70038","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143248782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, soil management practices that increase microbial CUE are relevant for sustainable agriculture and climate change mitigation. We conducted an exploratory literature review and evidence synthesis to compare microbial CUE between conventional tillage (CT) and low-intensity tillage systems (reduced tillage, RT and no-tillage, NT). The synthesis of 50 paired observations from 11 studies showed an overall increase in microbial CUE of 12% in soils under low-intensity tillage compared to CT (<i>p</i> = 0.02). Separate tillage contrasts of RT and NT versus CT (i.e., RT/CT and NT/CT) also showed higher microbial CUE for soils under low-intensity tillage with <i>p</i> = 0.06 and <i>p</i> = 0.05, respectively. The increase in CUE is likely due to improved substrate availability for microbial growth and/or changes in the microbial community induced by the contrasting tillage systems. However, the limited availability of quantitative data linking tillage-induced changes in these drivers to microbial CUE constrains further analysis. We also extracted available SOC data from the eligible studies, but this data did not provide evidence that increases in microbial CUE were correlated with increases in SOC content. Future studies should extend the emerging empirical data set and clarify the abiotic and biotic drivers through which tillage practices can be refined for better SOC management and climate change mitigation strategies. Further studies should also aim to better understand the link between microbial CUE and SOC dynamics, which is important for the representation of CUE in global SOC models.</p>","PeriodicalId":100834,"journal":{"name":"Journal of Sustainable Agriculture and Environment","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/sae2.70046","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143248793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mVOCs are critical in mediating interactions with biotic and abiotic stressors, including plant pathogens and environmental changes. These interactions contribute to enhanced plant resilience and foster beneficial ecological interactions. Biotechnological mVOCs have great potential in sustainable agriculture, especially natural pest management and crop protection. These applications include various disease control strategies, such as biosensors, highlighting the crucial role of mVOCs in promoting natural pest control and supporting sustainable development growth.

Arbuscular mycorrhizal (AM) fungi are more effective at colonising and functioning in rice under aerobic soil conditions, and this rice-AM fungi association could increase both gWUE and P acquisition efficiency (PAE). We used a precision irrigation platform to apply watering treatments (60% or 80% of soil field capacity) throughout the experiment. Four commercial Australian rice varieties were grown with or without inoculation with <i>Rhizophagus irregularis</i>, and with addition of P fertiliser at 10 or 25 mg P kg^–1 soil. Plants were grown to maturity (134–188 days after planting), after which grain yield, plant water use, gWUE, and PAE were determined. Overall, <i>R. irregularis</i> inoculation increased gWUE in all four rice varieties (by a mean of 14.4%), and increased grain yield and PAE in two varieties. Grain yields were primarily constrained by low water availability (mean 48.4% reduction), but P availability also limited yield in two varieties. Of the four, Topaz showed the greatest response to AM fungal inoculation, with increased qWUE and PAE. There is potential for AM fungal inoculation to increase the water use and P acquisition efficiencies of aerobically grown rice. However, the extent of these benefits depends on the specific rice variety, which highlights the importance of variety selection in transitioning to aerobic rice production in temperate regions and in enhancing the resilience of rice cultivation to climate change.</p>","PeriodicalId":100834,"journal":{"name":"Journal of Sustainable Agriculture and Environment","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/sae2.70040","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143117838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is of special relevance with climate change and the expected drier growing conditions in the future. Seed adaptation to this cropping method is hypothesized to be a fundamental factor to maximize these benefits, as well as the particular species combined. In this study we compared the performance of four cereal–legume mixed crops (wheat and oat mixed with lupin and lentil in pairs) with their respective monocrops. Each crop was sown using seeds adapted to monoculture and mixed cropping, respectively. Moreover, they were grown under early-season and late-season drought treatments and under control conditions. We measured above-ground vegetative biomass, seed yield and harvest index to evaluate crop production, drought resistance and the effect of seed adaptation on each mixed and monocrop. Our results show that mixed cropping either had a beneficial or neutral effect on crop yield, depending on the species combination and drought conditions, but the harvest index was higher in monocrops. We also confirmed that seed adaptation to a particular type of cropping is clearly a determining factor in its performance. In accordance with the insurance hypothesis, mixed cropping has the effect of protecting crop yields in the case of a sudden bad performance of one of the species, for example, caused by adverse environmental conditions. It is necessary to focus on effective species combinations which have the best responses to mixed cropping. In our study, we show that wheat–lentil mixtures performed poorly, while wheat–lupin showed the most promising results improving yield and drought resistance.
