Previous studies have primarily focused on comparing organic and conventional farming, with a particular emphasis on land-use intensification. However, less attention has been given to the specific effects of herbicides, insecticides, and fungicides on weed communities, including the species affected and the mechanisms driving these changes, based on farmer-recorded application data. Our study examined the impact of herbicide, fungicide, and insecticide use – both in terms of Treatment Frequency Index (TFI), i.e., intensity of application, and quantity (QA) – on weed communities in 96 non-organic cereal fields over 4 years. We did not detect any effect of insecticide metrics on weed communities. Interestingly, our results indicate that TFI of fungicide decreased weed abundance, whereas QA did not. In contrast, for herbicides, QA had a stronger negative impact on weed communities than TFI. This suggests that TFI of fungicide, which may reflect low-dose but frequent applications, could exert indirect and long-term effects on weed suppression. In comparison, QA of herbicide more directly reflects the toxic load delivered to weeds and is therefore a better predictor of their suppression. Our results reveal that herbicides are the main factor shaping weed communities by decreasing the abundance of non-target/non-competitive species while replacing them with competitive species. These findings point out the potential ineffectiveness of herbicide application on problematic weeds and emphasise the need to reconsider the use of herbicides to maintain weed diversity in agricultural landscapes.</div></div>","PeriodicalId":7512,"journal":{"name":"Agriculture, Ecosystems & Environment","volume":"397 ","pages":"Article 110026"},"PeriodicalIF":6.4,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145335022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigate how crop and non-crop field vegetation diversity, farming practices, climatic and landscape parameters jointly shape arthropod community structure and their services in the aerial and ground strata in tropical market gardening systems on La Réunion Island. We surveyed 22 open-field market gardening systems during two seasons. Using a multitrophic, piecewise structural equation modeling approach, we assessed direct and indirect cascading effects of local and landscape factors on arthropod diversity and pest regulation services. Results show that in aerial communities, non-crop vegetation richness generated a positive bottom-up trophic cascade. It enhanced herbivore diversity which, in turn, increased natural enemy richness, ultimately reducing pest abundance and crop damage, particularly during the dry season. In contrast, insecticide use suppressed natural enemy richness and reduced the effectiveness of pest regulation. Ground-dwelling communities were more strongly influenced by landscape fragmentation, semi-natural habitat cover, and temperature, with less evidence for structured trophic cascades. Overall, beneficial cascading effects of vegetation on pest regulation services in above-ground communities may outweigh the impacts of other management and landscape drivers. These findings underscore the potential of promoting vegetation diversity and reducing pesticide use as key strategies for enhancing natural pest regulation in tropical smallholder agroecosystems.</div></div>","PeriodicalId":7512,"journal":{"name":"Agriculture, Ecosystems & Environment","volume":"397 ","pages":"Article 110030"},"PeriodicalIF":6.4,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145335023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we examined the impacts of straw C/N ratio (high-C/N ratio maize straw and low-C/N ratio peanut straw) and varying amount of straw incorporation on Rs, soil properties, and extracellular enzyme activities. Rs exhibited a significant increase with the addition of straw, regardless of its C/N ratio. This can be attributed to the enhancement in microbial biomass and soil enzyme activity induced by straw incorporation. Low-C/N ratio straw contributed to a continuous increase in soil organic carbon (SOC). However, the SOC content remained unchanged with the increasing input of high-C/N ratio straw. Low-C/N ratio straw increased the soil C/N and C/P ratio, while high-C/N ratio straw increased the soil N/P. Microbial nutrient limitations, assessed through vector analysis, also showed contrasting effects. Increasing the rate of high-C/N straw application significantly reduced vector angle (VA), easing microbial phosphorus limitation. In contrast, higher rates of low-C/N straw increased vector length (VL) and VA, intensifying microbial carbon and phosphorus limitations. High-C/N straw alleviated microbial phosphorus limitation by altering microbial N/P-driven respiration, while low-C/N straw increased carbon limitation through changes in microbial nutrient dynamics.

The positive effects of flower strips extended beyond the strips themselves, as spillover effects were evident for several natural enemy groups, with increased abundances in adjacent crop fields. A trade-off was also observed: pest thrips were more abundant in crop tillers near flower strips than near controls. No effect of flower strips on aphid predation rates was observed. Decomposition rates were as high in flower strips as in controls, despite flower strips only being established for two years.

Similarly, restoration from CF and CG did not result in the anticipated significant increase in soil total carbon (lnRR<sub>++</sub> ∼0.08), largely due to the offsetting effects of organic and inorganic carbon. Afforestation in sandy land (SF) significantly increased soil total carbon, whereas its impact on grasslands (GF) was not significant. The effects of SF and FC on soil total carbon become more pronounced with higher precipitation levels. Conversely, the effect of CF on soil total carbon diminishes with rising temperatures.

Here, the activity, community structure, and abundance of these ammonia-oxidizers were examined in rice fields under three long-term (35 years) fertilization treatments (CK: no fertilizer, NPK: inorganic fertilizer, SNPK: straw returning combined with inorganic fertilizer) across four rice growth periods. It was observed that AOB activity dominated ammonia oxidation under CK treatment, accounting for 52.65 % of the total ammonia oxidation activity. In contrast, Comammox activity dominated ammonia oxidation under both NPK and SNPK treatments, accounting for 65.44 % and 63.29 % of total ammonia oxidation activity, respectively. The contribution of AOA activity to ammonia oxidation was the lowest (0.67 %-2.25 %) under the three fertilization treatments. Compared to CK, both treatments significantly increased abundance of AOA, AOB, and Comammox, and AOB exhibited the strongest stimulation (943.59 %-1445.83 %) by fertilization. Community structure of AOB and Comammox showed a stronger response to fertilization compared with AOA. Partial least squares analysis indicated that fertilization indirectly affected the activity of three types of ammonia-oxidizers by changing the soil physicochemical properties (e.g., pH, organic carbon content, and NH<sub>4</sub><sup>+</sup>-N content) and the community structure of ammonia-oxidizers. Overall, our findings highlight the importance of Comammox in nitrification in long-term fertilized paddy soils, contributing to a better comprehension of the roles of different types of ammonia-oxidizers in nitrogen cycle.</div></div>","PeriodicalId":7512,"journal":{"name":"Agriculture, Ecosystems & Environment","volume":"396 ","pages":"Article 110022"},"PeriodicalIF":6.4,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145263328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
