To address this, a study was conducted on intercropping <i>Vernicia fordii</i> with <i>Polygonatum odoratum</i>, a Chinese herbal medicine, to investigate its effects on rhizosphere soil microorganisms and potential for accelerated economic gains. Comparisons were drawn with monocultures of both <i>P. odoratum</i> and <i>V. fordii</i>. Utilizing 16S rDNA sequencing analysis, the study unveiled a profound impact of intercropping on the rhizosphere soil microbial community. Specifically, the abundance of certain bacterial communities such as Actinomycetes, Bacteroidetes, and Chloroflexi, as well as fungal communities like Ascomycota and Basidiomycota, underwent significant changes under intercropping conditions. Within the bacterial community, the relative abundance of Actinobacteria, Myxococcola, and Chloroflexi increased notably by approximately 33.3%, 50%, and 50%, respectively, while Proteobacteria and Acidobacteria decreased significantly by 16.7% and 20%, respectively (<i>p</i> &lt; 0.05). Concurrently, Ascomycota and Basidiomycota in the fungal community showed a significant increase in relative abundance by 10% and 5%, respectively. Functional predictions further indicated enhanced metabolic activities related to nitrogen fixation and chitin decomposition.Moreover, intercropping led to a marked increase in soil nutrient content, including organic matter, available potassium, alkaline hydrolyzable nitrogen, and sucrase activity, which are crucial for the advancement of biogeochemical processes. In terms of plant growth, <i>P. odoratum</i> under intercropping exhibited significant advantages, with increased plant height, ground diameter, and biomass. Notably, the ground diameter increased by 9.75% and biomass by 28.8%. Additionally, the chemical composition of <i>P. odoratum</i> underwent changes, with polysaccharides, total flavonoids, and total saponins showing increases of 1%, 32.9%, and 13.9%, respectively, whereas total phenolic content decreased by 19.0% (<i>p</i> &lt; 0.05). In summary, intercropping not only alters the composition and abundance of soil microbial communities and enhances soil nutrient content but also promotes the growth and accumulation of specific chemical components in <i>P. odoratum</i>. These findings have positive implications for agricultural and forestry production, offering valuable insights for improving agricultural efficiency and economic benefits.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"99 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143824603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Integrated intercropping systems offer sustainable solutions, promoting biodiversity and ecosystem health. This research explored the long-term effects of weed control and row spacing on eucalyptus (<i>Eucalyptus grandis)</i> and pinus (<i>Pinus taeda)</i>, intercropped with switchgrass (<i>Panicum virgatum</i>), within a Uruguayan setting. Using spatiotemporal mixed models, we aimed to improve experimental accuracy and understand the dynamics between stand growth and agroforestry management. Significant impacts of spacing and weed control were found on both wood volume per hectare and individual volume. Optimal results per hectare were achieved with a 7-m row spacing for both species at the hectare level, while a 12-m spacing was more favorable for individual tree sizes. Low and medium weed control affected per tree and hectare wood volume productivity. Significant differences in switchgrass productivity were found between high and low weed control in pinus. The use of spatiotemporal structures has resulted in a better fit for the models in all cases, and it is noteworthy to consider the heterogeneous variances over the years. This study underscores the value of spatiotemporal analysis in agroforestry experimentation, integrating heterogeneous structures with temporal dynamics. These insights advance agroforestry by optimizing productivity and sustainability, offering adaptable strategies for regions sharing similar environmental profiles.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"99 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, studies of the impacts of adoption of agroforestry practices on smallholder farmer livelihoods are limited to field-scale assessments and landscape potential. In this paper, we assess the difference in terms of farming system performance between agroforestry adopters and non-adopters in northwest Viet Nam using propensity score matching (PSM) calculating the average treatment (agroforestry adoption) effect on the treated (adopters) on core economic, environmental, and social indicators. The results of the PSM indicate an increase in revenues of about 8 million VND ha⁻¹ yr⁻¹ (about 325$) per household when adopting agroforestry, but a counterintuitive outcome regarding erosion. This outcome is likely due to an improperly selected farmer control group, which is located on less erosion-prone land, as well as the presence of immature trees in agroforestry systems, whose canopies have not yet contributed to reducing erosion. A typology of adopters was produced and revealed a wide diversity of agroforestry adoption pathways across the population, which may have blurred the results of the PSM. Six farming household types were obtained ranging from ‘Off-farm income-dependent farmers’ with low proportion of agroforestry to ‘Specialists mixed agroforesters’ with higher proportion of agroforestry practices on their farm and different levels of input intensity in their farming systems. This typology highlights the need for greater context awareness in farming system research and proper control of the agroforestry type, the proportion of agroforestry in the farming systems, and the maturity of the agroforestry system. This will help to better capture the real-life, farm-scale impacts of agroforestry practices.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"99 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10457-025-01170-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The silvopastoral system led to microclimatic conditions accounting for better thermal distribution and for fewer daily heat–accumulation hours over the 2 year study. Forage production and nutritional value were significantly higher and seasonally stable, and it led to better animal performance per area than the traditional system. Furthermore, enteric methane emissions were lower during the rainy season and the forest component had positive influence on the carbon stock in stems.
