“…forest at Ñuble Region, which is under severe degradation processes resulting from: (i) over-logging (e.g., uncontrolled woodlots), (ii) overgrazing, (iii) browsing, limiting forest regeneration, and (iv) allotment and over-utilization of areas destined to agriculture. To address this situation, two different AFSs were established in 2016, an SPS and A GRO F RST , each divided into 3 plots of 1.33 ha [34,38,39] (Figure 1).…”

“…However, considering the extensively reported benefits of AFSs, very few but relevant experiences of using AFSs in temperate native forests have been reported in Chile. For instance, it has been observed that these systems promote a range of 30-50% of solar irradiance, which enhances the plant diversity of the understory, increases prairie productivity, and reduces wind speed by up to 200% in Ñirre and Nothofagus forests (Nothofagus antartica) [33][34][35], promotes greater SOC QSEQ accumulation rates than observed in Nothofagus obliqua forests [36], and doubles the SOC QSEQ capacity compared with commercial forestry plantations [37].…”

“…Nowadays, about 51.4-52.7 Pg CO 2eq y −1 are globally emitted by anthropogenic activities [1][2][3], where 7.1-8 CO 2eq y −1 are generated via agriculture, including 3.2-5.7 Pg released to land use changes [1,4]. Livestock symbolizes probably the most relevant 30-50% of solar irradiance, which enhances the plant diversity of the understory, increases prairie productivity, and reduces wind speed by up to 200% in Ñirre and Nothofagus forests (Nothofagus antartica) [33][34][35], promotes greater SOC Q SEQ accumulation rates than observed in Nothofagus obliqua forests [36], and doubles the SOC Q SEQ capacity compared with commercial forestry plantations [37].…”

Agroforestry systems (AFSs) have gained recognition as a land use strategy to address food security and climate change. They involve intentionally cultivating trees alongside crops and/or animals. AFSs cover approximately 5% of the global forest area and promote sustainable soil conservation, including soil organic carbon (C) sequestration (CSEQ). In some areas of Chile, AFSs are used to preserve the ecological value of native forests. This study evaluates the effects of two AFSs, namely, an agroforest for fodder production (AGROFRST) and Silvopastoral (SPS), within a degraded native forest (Nothofagus obliqua sp.). The evaluation focuses on their impact on CSEQ capacity and soil quality (SQ), using soil quality indexes (SQIs) derived from 30 soil quality indicators (SINDs) related to physical, chemical, and microbiological properties at two depths (0–5 and 5–20 cm). The results for the total depth analyzed (0–20 cm) indicate an average CSEQ of 6.88 and 4.83 Mg C yr−1 and a global SQI of 37.8% and 31.0% for AGROFRST and SPS, respectively. Among the thirteen SINDs that demonstrated significant differences (p < 0.05), five were associated with the considered depths (P+, Ca2+, S, ECEC, and AlSAT), three differed between AGROFRST and SPS (BD, NH4+, NO3−), while SOC, K+, and Mg2+ varied across all conditions (e.g., combinations of systems and depths), and β-GLU and NMIN differed in a single condition. However, almost all 30 SINDs analyzed showed higher values at the 0–5 cm depth, indicating the positive effects of soil organic matter (SOM)/SOC additions. Significant interactions (Pearson’s correlation) revealed that SOC correlated with most SINDs (e.g., N, NH4+, P+, K+, Ca2+, Mg2+, S, ECEC, NMIN). These findings suggest that both AGROFRST and SPS systems have similar capabilities in restoring the ecological value of native Nothofagus forests while providing conditions for productive and complementary use. This sustainable option offers opportunities for cattle production alongside ecological restoration efforts and provides a possible strategy to generate public policies related to the ecosystem services of agroforestry systems.

“…Soil microbial community activities affect soil fertility and play an important role in organic matter, humus and soil nutrient cycling and conversion ( Kirk et al, 2004 ). As a result, the importance of soil microorganisms in the soil ecosystem has received increasing attention ( Neira et al, 2021 ). The abundance and diversity of different types of soil microorganisms can affect soil physical and chemical properties ( Christel et al, 2023 ).…”

IntroductionEnhancing the planning of the forest-agricultural composite model and increasing the efficiency with which forest land is utilized could benefit from a thorough understanding of the impacts of intercropping between forests and agriculture on soil physicochemical properties and microbial communities.MethodsPopulus cathayana × candansis cv. Xinlin No.1 and Glycine max intercrop soils, along with their corresponding monocrops, were used in this study’s llumina high-throughput sequencing analysis to determine the composition and diversity of soil bacterial and fungal communities.ResultsThe findings indicated that intercropping considerably raised the soil’s total phosphorus content and significantly lowered the soil’s carbon nitrogen ratio when compared to poplar single cropping. Furthermore, the total carbon and nitrogen content of soil was increased and the soil pH was decreased. The sequencing results showed that intercropping had no significant effect on soil alpha diversity. Intercropping could increase the composition of fungal community and decrease the composition of bacterial community in poplar soil. At the phylum level, intercropping significantly increased the relative abundance of four dominant phyla, i.e., Patescibacteria, Proteobacteria, Patescibacteria and Deinococcus-Thermus. And the relative abundances of only two dominant phyla were significantly increased. It was found that soil total phosphorus and available phosphorus content had the strongest correlation with soil bacterial community diversity, and soil pH had the strongest correlation with soil fungal community diversity.DiscussionThe results of this study were similar to those of previous studies. This study can serve as a theoretical foundation for the development of a poplar and black bean-based forest-agricultural complex management system in the future.

“…Especially in silvopastoral systems, organic carbon accumulation and recycling of nutrients, mainly nitrogen, are higher than in grassland monocultures (Barros et al, 2018;Berthrong et al, 2009;Beule et al, 2019). Edaphic microbiota studies in Latin American tropical Silvopastoral systems are scarce and have focused on the comparison of bacterial and fungal diversity between open grasslands and the inclusion of plants associated with mycorrhizae, such as legumes (Barros et al, 2018(Barros et al, , 2021Beule et al, 2019) or trees of the genus Nothofagus (Neira et al, 2021). To our knowledge, comparisons of the diversity of the edaphic and rhizosphere microbiota between monoculture plantations of tree native species (in which only trees of a single species have been planted) and silvopastoral systems (in which, additionally to the trees, some grasses are cultivated and sheep are grazed) have never been conducted.…”

Numerous works have reported the impact on soil properties and microbial communities of intensive soil management, but very little is known about the impact caused by traditional agroforestry systems carried out by smallholders. To investigate whether the different smallholder's management between a monoculture plantation of Cordia dodecandra trees and a Silvopastoral system has led to a divergence in these ecosystems, soil properties, as well as soil and Cordia dodecandra rhizosphere microbial communities were analysed by MiSeq amplicon sequencing. The main findings were (i) Large variation in the soil properties of the Silvopastoral system suggests that it has a greater heterogeneity; (ii) Organic carbon, organic matter, carbonates, nitrogen, inorganic phosphorous and calcium, was significantly higher in the soil of the Silvopastoral system. (iii) The relative abundance of the major prokaryotic orders in soil and rhizospheres displayed small differences between the two agroforestry systems, and diversity indexes were slightly higher in the Silvopastoral system. (iv) The fungal orders Hypocreales and Pleosporales were more abundant in the Silvopastoral system than in the monoculture. Other evaluated parameters showed only minor or no difference. Thus, the main conclusion is that these soils have diverged in some properties and fungal orders, but not in their prokaryotic communities. To our knowledge, this is the first report on the divergence in soil properties and microbiota of these two extended smallholder agroforestry systems and therefore can serve as reference for future works.
