The objective of this study was to assess whether intercropping and its combination with N fertilisation are adequate practices to improve the soil aggregate stability and organic matter quality. An irrigated on-farm experiment was established in northeastern Spain to evaluate the effect of seven cropping systems (faba bean-durum wheat, pea-durum wheat, and rapeseed-pea intercropping and the respective sole crops) and two N-fertiliser rates (0 vs. 75 kg N ha⁻¹). Several soil variables were analysed in bulk soil: water-stable macro- and microaggregates, soil organic carbon (SOC), soil total nitrogen (STN), reduced permanganate (Per_red), particulate organic matter (POM) and carbon (POC), mineral-associated organic matter (MAOM) and carbon (MAOC) and microbial biomass carbon (MBC) and nitrogen (MBN). Also, SOC, Per_red and nitrogen (N) storage within aggregates were determined. Intercropping did not increase the share of water-stable aggregates nor SOC levels, but SOC concentration was higher in macro- (2.34 g C 100 g⁻¹) than in microaggregates (1.89 g 100 g⁻¹). Intercropping did also not affect STN, but the mineral N-fertilised treatment increased both SOC (2.24 vs. 2.08 g 100 g⁻¹) and STN (0.193 vs 0.177 g 100 g⁻¹) significantly in bulk soil. This study showed that after a few years upon establishment, intercropping had not enhanced the soil aggregate stability significantly and as a sole practice intercropping does not improve soil C and N concentrations nor their active fractions.</div></div>","PeriodicalId":7512,"journal":{"name":"Agriculture, Ecosystems & Environment","volume":"385 ","pages":"Article 109563"},"PeriodicalIF":6.0,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143454654","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}

Diversification aims to address these issues but varies across time, space and system levels, which hinders an assessment of success of diversification and makes transfer to other regions difficult. We classified diversification measures from field to landscape through a systematic review of 142 papers on intensive agricultural systems in temperate climates. Most measures were at field and farm levels, with fewer at landscape level. Since biodiversity requires provision and maintenance at the landscape level rather than just at the field or farm level, the limited emphasis on landscape-level diversification measures highlights a significant knowledge gap. We further analyzed the impact of diversification on sustainability (integration of environmental, economic, social targets) and resilience capacities (robustness, adaptation, transformation). We show that specific diversification levels were linked to specific sustainability targets and resilience capacities. Environmental aspects are mainly addressed at the field level, economic aspects at the farm level, and social aspects, which are less frequently addressed, are also primarily tackled at the farm level. Resilience is often equated with robustness towards economic (farm) stability. Adaptation relates to climate change and economic instability, while transformation, though rarely addressed directly, emphasizes societal change. Our findings suggest that the concepts of resilience and sustainability are interconnected: resilience can be understood as a property of a system, while sustainability is the overarching target. In literature, transformation relates to societal changes for better integrating social, economic and environmental targets. In contrast, robustness and adaptation address environmental or economic aspects with less linkage to integration of sustainability as a whole. While agricultural diversification is often associated with improved resilience and sustainability, most studies on diversification remain vague about the causal linkage to those concepts. Literature on diversification often focuses only on individual aspects of sustainability or resilience, which undermines both concepts, as it is the holistic consideration of all aspects together that makes a system sustainable or resilient. Our research highlights that diversification at all spatial levels is necessary to achieve resilient and sustainable systems, as each level of diversification addresses distinct sustainability goals or resilience capacities.</div></div>","PeriodicalId":7512,"journal":{"name":"Agriculture, Ecosystems & Environment","volume":"385 ","pages":"Article 109547"},"PeriodicalIF":6.0,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143454653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we simulated disturbance to the indigenous microbial community through ASD treatment, followed by the application of <em>Bacillus subtilis</em> and <em>Trichoderma harzianum</em> bio-organic fertilizers (BS and TH treatments) to restore soil microorganisms and improve soil health in a field experiment. The results showed that the combination of ASD and bio-organic fertilizers was more effective in reducing the abundance of <em>Ralstonia solanacearum</em> (<em>R. solanacearum</em>) in rhizosphere soil, lowering the incidence of tomato bacterial wilt, and increasing tomato yield compared to single ASD or bio-organic fertilizer treatments. The treatments of ASD+TH and ASD+BS significantly increased soil health index (SHI) by 31.9 % and 30.4 %, respectively. In addition, ASD+BS and ASD+TH treatments increased the abundance of <em>B. subtilis</em> and <em>T. harzianum</em> in rhizosphere soil, respectively, increased the the diversity and richness of bacterial communities, and reduced the negative correlation of bacterial communities in the co-occurrence network. Variation partitioning analysis and principal coordinate analysis revealed that ASD treatment was the primary driver of changes in bacterial community composition and structure. Microbial function prediction analysis showed that ASD combined with bio-organic fertilizers increased the relative abundance of carbohydrate metabolic pathways in the bacterial community, but decreased the relative abundance of plant pathogen function. Overall, the effective control of tomato bacterial wilt through combined ASD and bio-organic fertilizers may be attributed to the direct reduction of <em>R. solanacearum</em>, or to the improvement of soil health and the optimization of soil bacterial community.</div></div>","PeriodicalId":7512,"journal":{"name":"Agriculture, Ecosystems & Environment","volume":"385 ","pages":"Article 109562"},"PeriodicalIF":6.0,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143464608","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}

We examined the impact of landscape composition and configuration at different spatial scales on the taxonomic diversity and functional composition of spider assemblages in our target patches. Overall, we did not observe differences in species richness or total abundance of spiders between modern and traditional agricultural landscapes. However, functional composition and community structure differed strongly between landscape types, and were also affected by compositional and configurational heterogeneity. In particular, the size and configuration of crop fields was an important factor in shaping spider assemblages. This suggests that modern agricultural landscapes may result in species turnover due to species-specific responses rather than declines in species richness. Therefore, species numbers alone may not be a good indicator of intensification.

However, the SOC dynamics and its compositional changes during grassland restoration are not fully understood. We investigated the relative contributions of microbial- and plant-derived C to SOC in both topsoil (0–10 cm) and subsoil (10–20 cm) over a 27-year restoration chronosequence in desertified grasslands, using resampling at the same site. We used amino sugars as biomarkers for microbial-derived C, and light fraction organic carbon (LFOC) and particulate organic carbon (POC) as indicators for plant-derived C. Grassland restoration increased SOC from 3.8 to 8.1 g kg⁻¹ in topsoil and from 2.1 to 4.1 g kg⁻¹ in subsoil. Concurrently, microbial necromass carbon (MNC), LFOC, and POC also increased in both soil layers. The proportion of SOC derived from MNC decreased as restoration progressed, while the contribution of LFOC increased, likely due to the continuous input of root biomass and litter after grazing exclusion. These findings support the emerging view that plant-derived C plays a key role in SOC accumulation during the later stages of grassland restoration. Thus, SOC appears less stable and more susceptible to disturbances as restoration progressed, indicating potential risks for C loss. Fungal necromass C was 2.4–2.9 times bacterial necromass C and contributed more to SOC. Random Forest models and correlation analyses revealed that Fe and Al oxides, LFOC, and the SOC/total phosphorus (TP) ratio were key regulators of microbial-derived C in topsoil. Plant-derived contribution to SOC depended primarily on total nitrogen, restoration duration, and TP. We conclude that both microbial- and plant-derived C increased during grassland restoration, but their relative contributions to SOC followed contrasting patterns. These varying C sources during restoration have important implications for SOC stability and vulnerability, and can guide future management strategies for optimizing C sequestration in dryland ecosystems.</div></div>","PeriodicalId":7512,"journal":{"name":"Agriculture, Ecosystems & Environment","volume":"385 ","pages":"Article 109579"},"PeriodicalIF":6.0,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143454652","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}

The experiment involved three treatments of rotational management with the same level of grazing intensity (1 sheep unit per ha in the first year and 1.3 sheep unit per ha for the next two years), including intensive rotational grazing (livestock rotated every 3–5 days), traditional rotational grazing (livestock rotated every 15 days), and continuous grazing (without livestock rotation). In addition, this experiment set up “no grazing treatment” as the reference and represents the widely used policy of “grazing forbidden”. Compared with previous studies, this study first implemented rotational grazing at a low level of grazing intensity to obey the rangeland policy of Chinese governments, which aimed to balance the forage demand of livestock and the ecosystem conservation. The results revealed that the aboveground biomass and root biomass (0–10 cm deep) were significantly higher in the intensive rotational grazing treatment than in the other two grazing treatments. Moreover, the biomass of the dominant species (<em>Leymus chinensis</em>) and its proportion in the community were also higher in the intensive grazing treatment. Intensive rotational grazing could also promote the weight gain of grazing sheep. However, intensive rotational grazing did not improve the carbon sequestration of rangeland. These results indicated that intensive rotational grazing had considerable advantages in realizing the sustainable management of grazing grasslands when grazing intensity was at a relatively low level, which aims to balance plant growth and livestock production of grasslands. Furthermore, our results suggest that intensive rotational grazing is beneficial for promoting the progressive succession of degraded grasslands and providing economic revenue for local herders, thus worth studying in more regions and rangeland scenarios.</div></div>","PeriodicalId":7512,"journal":{"name":"Agriculture, Ecosystems & Environment","volume":"384 ","pages":"Article 109558"},"PeriodicalIF":6.0,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143445569","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}

These inhibitory effects on soil N-oxide emissions may be mainly attributed to the increased abundance of <em>nosZ</em> genes and the key species enrichment in the bacterial co-occurrence networks related to N₂O reduction (<em>Desulfobacteroata</em> and <em>Verrucomicrobiota</em>), and decreased in <em>nirS</em> genes. The stimulation of vegetable yield and the incidence of plant wilt suppression following organic substitution accompanied by <em>Bacillus velezensis</em> SQR9 inoculation was probably due to the promoted efficiency of N uptake and utilization by vegetables.
