“…Eddy and Yang [2] reported higher total nitrogen stock and SOC levels up to 1 m in 24-year-old Castanea mollisima-Asima trilobala agroforestry than in a zero tillage corn-soybean rotation system in the USA. Mesfin and Haileselassie [9] reported increased SOC, total N, available phosphorus, exchangeable potassium, and SOC stock levels by 11.9-91.5%, 22.2-125.0%, 31-71%, 32-151.6%, and 15.2-90.9%, respectively, in the soil under the tree canopy compared to outside the canopy. In croplands, the presence of a few scattered trees greatly increases the nutrient status of the soil and decreases the requirement for an additional input of fertilizer.…”

“…In terms of managing soil fertility, Faidherbia albida has the most potential as compared to A. sieberiana, Balanites aegyptica, Cordia africana, Croton macrostachyus, and Ziziphus spina-christi. In Ethiopian farms, Faidherbia albida reduces allelopathy and shadowing effects by dropping its leaves during the wet season and encouraging crop production under its canopy [9]. Planting tree species on croplands is an effective approach to enhance the nutrient status of the soil and lower the requirement for external fertilizer inputs.…”

“…Soil organic carbon has been depleted as a result of heavy tillage, intensive cropping, and insufficient C inputs [8]. It is acknowledged that substantial soil erosion and poor soil fertility are the primary biophysical causes of food insecurity [9]. Therefore, one of the main objectives in the development of sustainable farming techniques is to improve soil health [2].…”

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.

“…Given the increasing pressure for public policies that encourage sustainable agriculture, and the expansion of the consumer market for organic products (MULLER et al, 2017;SAZVAR;RAHAMANI;GOVINDAN, 2018), improving and assessing the impact of management systems that are based on the reuse of organic waste is important for guaranteeing the environmental and economic viability of these methods. In this scenario, monitoring the attributes of soil quality is an important indicator of the productive potential and restrictions of the type of management employed (CHAVEIRO et al, 2022;MESFIN;HAILESELASSIE, 2022;PAGE;DANG;DALAL, 2020).…”

Monitoring the spatial variability of soil attributes is an important tool in crop management. Multivariate statistical methods and geostatistics were jointly applied to evaluate the infl uence of diff erent attributes on spatial variability in the soil. The aim of this research was to apply multivariate principal component analysis to map the spatial variability of the soil in an area subjected to diff erent methods of conservation management and identify the most relevant physical and chemical attributes. Disturbed and undisturbed soil samples were collected and georeferenced at 99 diff erent points in the study area at depths of 0.00 -0.10 m and 0.10 -0.20 m to measure the physical and chemical attributes of the soil; multivariate principal component analysis (PC) was then applied to the data.Geostatistics was applied to the PCs showing greater explanatory capacity, evaluating spatial dependence, and generating maps of spatial variability. The variance in the soil attributes was explained by the fi rst eight PCs. Soil density, particle density and pH had the greatest infl uence on the spatial variability of the soil since they showed the highest correlation with the PC with the greatest explanatory power. The PCs that correlated with at least two of the soil attributes showed moderate (PC1 and PC6) and strong (PC2, PC4 and PC5) spatial dependence. The generated maps helped identify the joint infl uence of the variability of the most relevant attributes, making it possible to characterise regions under diff erent methods of conservation management.

“…Sustainable food production is one of the concerns in the global environmental dynamics such as climate change and natural resource degradation [ [1] , [2] , [3] , [4] ]. The increasing global food demand due to growing human population calls the importance of sustainable soil fertility management and crop production [ [5] , [6] , [7] , [8] ].…”
