“…A 24-year-old Castanea mollisima-Asima trilobala agroforestry system showed an intermediate level of microbial biomass C (1.99 Mg ha −1 ) between a secondary forest (1.7 Mg ha −1 ) and zerotillage corn-soybean rotation system (1.36 Mg ha −1 ) in the USA [2]. However, a study by Zhu et al [60] in China reported that poplar shelterbelts reduced the diversity of soil fungi, but they found more ectomycorrhizal and fewer harmful fungi than in farmlands. They also found that the relative abundance of Basidiomycota increased from 14.72 to 19.18%.…”

“…Ectomycorrhizal fungi can develop symbiotic relationships with trees, absorbing carbon from the host and assisting the host in absorbing nutrients such as nitrogen and phosphorus. Fungi that are pathotrophic take nutrients from their host's cells and inhibit the growth of plants [60]. Instead of increasing the alpha diversity, agroforestry systems improve the soil microbial diversity primarily by creating a treerow-associated microbiome that differs in composition from the crop row microbiome (i.e., greater beta diversity in agroforestry systems) [62].…”

Agroforestry integrates woody perennials with arable crops, livestock, or fodder in the same piece of land, promoting the more efficient utilization of resources as compared to monocropping via the structural and functional diversification of components. This integration of trees provides various soil-related ecological services such as fertility enhancements and improvements in soil physical, biological, and chemical properties, along with food, wood, and fodder. By providing a particular habitat, refugia for epigenic organisms, microclimate heterogeneity, buffering action, soil moisture, and humidity, agroforestry can enhance biodiversity more than monocropping. Various studies confirmed the internal restoration potential of agroforestry. Agroforestry reduces runoff, intercepts rainfall, and binds soil particles together, helping in erosion control. This trade-off between various non-cash ecological services and crop production is not a serious constraint in the integration of trees on the farmland and also provides other important co-benefits for practitioners. Tree-based systems increase livelihoods, yields, and resilience in agriculture, thereby ensuring nutrition and food security. Agroforestry can be a cost-effective and climate-smart farming practice, which will help to cope with the climate-related extremities of dryland areas cultivated by smallholders through diversifying food, improving and protecting soil, and reducing wind erosion. This review highlighted the role of agroforestry in soil improvements, microclimate amelioration, and improvements in productivity through agroforestry, particularly in semi-arid and degraded areas under careful consideration of management practices.

Aims: Conversion of land from forest to cropping has a serious effect on soil phosphorus and its fractions Results: Land use is now widely understood to be a primary factor in environmental change across all time and space scales. The purpose of this research was to ascertain how different land uses affected the concentration of phosphorus in soil. Soil phosphorus (P) reserves are depleted when land is converted from natural vegetation to permanent agricultural cropping. The transformation of North-Western Himalayas from a forest-dominated to a grassland-dominated ecosystem is just one example of the diversity of land significantly less soil aggregation occurred when agricultural land was cleared of its native vegetation. Total organic carbon in soils was reduced when grassland was converted to cropland. Reduced total organic carbon (TOC) concentrations by 62-79% and organic phosphorus (Po) concentrations by 47-53%. Even though, the total silt+clay fraction's contribution was negligible, it contained a significant amount of C and Po reserves and the C/Po ratio has been holding fairly steady, they have proven to be more robust. This impact of cropping on soil P reserves has been demonstrated in research, but changing land use practices can alleviate these problems significantly.

“…Overall, the average yield variation at 0.5-15 H, namely the intensity of the legacy effect, is 0.98 ± 0.03%. As mentioned in the introduction, this legacy effect is likely the result of lingering effects on soil properties [21,62]. The accumulated improvement of farmland soil structure and soil quality caused by shelterbelts could still partly remain after cutting [24,26].…”

Shelterbelts (or windbreaks) can effectively improve the microclimate and soil conditions of adjacent farmland and thus increase crop yield. However, the individual contribution of these two factors to yield changes is still unclear since the short-term effect from the microclimate and the accumulated effect from the soil jointly affect crop yield. The latter (soil effect) is supposed to remain after shelterbelt-cutting, thus inducing a post-cutting legacy effect on yield, which can be used to decompose the shelterbelt-induced yield increase. Here, we develop an innovative framework to investigate the legacy effect of post-cutting shelterbelt on corn yield by combining Google Earth and Sentinel-2 data in Northeastern China. Using this framework, for the first time, we decompose the shelterbelt-induced yield increase effect into microclimate and soil effects by comparing the yield profiles before and after shelterbelt-cutting. We find that on average, the intensity of the legacy effect, namely the crop yield increment of post-cutting shelterbelts, is 0.98 ± 0.03%. The legacy effect varies depending on the shelterbelt–farmland relative location and shelterbelt density. The leeward side of the shelterbelt-adjacent farmland has a more remarkable legacy effect compared to the windward side. Shelterbelts with medium–high density have the largest legacy effect (1.94 ± 0.05%). Overall, the legacy effect accounts for 47% of the yield increment of the shelterbelt before cutting, implying that the soil effect is almost equally important for increasing crop yield compared to the microclimate effect. Our findings deepen the understanding of the mechanism of shelterbelt-induced yield increase effects and can help to guide shelterbelt management.
