Throughout, spiders were sampled in (fragments of) wet meadows by pitfall trapping. 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. In order to preserve spider diversity in agricultural landscapes it is necessary to consider the effects of compositional and configurational heterogeneity on taxonomic diversity as well as functional traits and community structure.</div></div>","PeriodicalId":7512,"journal":{"name":"Agriculture, Ecosystems & Environment","volume":"385 ","pages":"Article 109560"},"PeriodicalIF":6.0,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143444452","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, a three-year experiment was performed to evaluate the effects of intensive rotational grazing on the rangeland ecosystem in a typical steppe in Inner Mongolia, China. 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}

Utilizing a field experiment in typical tropical continuous and rotational vegetable cultivation systems, we examined how organic fertilizer substitution for mineral fertilizer accompanied by <em>Bacillus velezensis</em> SQR9 inoculation influenced N-oxide emissions, vegetable yields, and successive cropping obstacles. Partial substitution with organic fertilizer accompanied by <em>Bacillus velezensis</em> SQR9 inoculation increased vegetable yields based on alleviating the incidence of plant wilt and decreased N-oxide emissions by 11 % compared to the partial substitution and by 35 % compared to conventional mineral fertilizer. 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. Although the increased amount of organic fertilizer application was another strategy for stimulating vegetable yields and reducing the incidence of plant wilt, it also obviously stimulated soil N-oxide emissions. Rotational cropping improved vegetable yields while decreasing soil N-oxide emissions by 10 % when compared to the continuous cropping system.

A meta-analysis was conducted based on 2525 pairs of observations to investigate the effects of straw return combined with no tillage (NT), reduced tillage (RT), and conventional tillage (CT) on SOC content in wheat–maize rotation systems in the North China Plain. The results indicated that, compared with straw removal, straw return with NT and RT significantly increased the SOC content in the 0–40 cm layer, which was attributed to reduced soil disturbance and promoted SOC surface accumulation. The largest increase was observed in the 0–20 cm layer under NT (12.7 %) and in the 20–40 cm layer under RT (12.7 %). CT showed the greatest increase in SOC content below 40 cm (10.0 %), and RT did not affect SOC below the 40 cm layer relative to CT because deep tillage increased inputs of straw C and transferred topsoil with higher SOC to the subsoil layer. Mean annual precipitation, initial SOC content, and straw quantity were the major drivers regulating the response of SOC sequestration to straw return. Specifically, regions with mean annual temperatures above 15℃ and precipitation over 700 mm had a greater increase in SOC under straw return. Straw return under NT and RT led to the largest increase in SOC content when initial SOC was between 5 and 10 g kg⁻¹ or with a straw return duration of 16–20 years. Straw return under CT showed the greatest increase when initial SOC exceeded 10 g kg⁻¹ or with a straw return duration of 6–10 years.

Limited nitrogen (N) uptake of renewed grassland during autumn may, however, increase the potential risk of NO₃ leaching and N₂O emission. Potential options to mitigate these N losses are reduction in tillage intensity and N application rate, or the application of nitrification inhibitors. We assessed the effects of these measures as well as timing of renewal and the conversion to grassland to maize on NO₃ leaching and N₂O emissions after one growing season. Five replicated field experiments were conducted of one year each at five locations in the Netherlands. We measured crop yield, soil mineral N, NO₃ concentrations in groundwater and N₂O emission. Averaged over all experiments, the measures had an effect on NO₃ concentration in groundwater, although not significant. The highest NO₃ concentrations in groundwater were observed after autumn renewal (17.2 mg NO₃-N L⁻¹), autumn renewal combined with mitigation strategies (12.8–19.4 mg NO₃-N L⁻¹) and conversion to maize (12.5–12.8 mg NO₃-N L⁻¹), with all of these treatments exceeding the European norm of 11.3 mg NO₃-N L⁻¹. Concentrations after renewal in spring were lower (3.1 mg NO₃-N L⁻¹) and did not lead to an increase compared to the control (4.4 mg NO₃-N L⁻¹).
