“…Here, the rise in TOC was undoubtedly one of the responsible factors for the observed differences in microbial beta diversity between AF and SC systems. Recently, Abbasi Surki et al (2020b) reported that the AF systems sequestration of carbon in the soil and offer higher soil moisture to the next crop. Thus, we can suggest that the soil microbial communities of AF can be structured by effects of the above-ground olive leaf litterfall, woody debris and/ or olive root turn-over, which is not the case in SC.…”

Agroforestry (AF) is a promising land-use system to mitigate water deficiency, particularly in semi-arid areas. However, the belowground microbes associated with crops below trees remain seldom addressed. This study aimed at elucidating the effects of olive AF system intercropped with durum wheat (Dw), barely (Ba), chickpea (Cp), or faba bean (Fb) on crops biomass and their soil-rhizosphere microbial networks as compared to conventional full sun cropping (SC) under rainfed conditions. To test the hypothesis, we compared the prokaryotic and the fungal communities inhabiting the rhizosphere of two cereals and legumes grown either in AF or SC. We determined the most suitable annual crop species in AF under low-rainfed conditions. Moreover, to deepen our understanding of the rhizosphere network dynamics of annual crops under AF and SC systems, we characterized the microbial hubs that are most likely responsible for modifying the microbial community structure and the variability of crop biomass of each species. Herein, we found that cereals produced significantly more above-ground biomass than legumes following in descending order: Ba > Dw > Cp > Fb, suggesting that crop species play a significant role in improving soil water use and that cereals are well-suited to rainfed conditions within both types of agrosystems. The type of agrosystem shapes crop microbiomes with the only marginal influence of host selection. However, more relevant was to unveil those crops recruits specific bacterial and fungal taxa from the olive-belowground communities. Of the selected soil physicochemical properties, organic matter was the principal driver in shaping the soil microbial structure in the AF system. The co-occurrence network analyses indicated that the AF system generates higher ecological stability than the SC system under stressful climate conditions. Furthermore, legumes’ rhizosphere microbiome possessed a higher resilient capacity than cereals. We also identified different fungal keystones involved in litter decomposition and drought tolerance within AF systems facing the water-scarce condition and promoting crop production within the SC system. Overall, we showed that AF reduces cereal and legume rhizosphere microbial diversity, enhances network complexity, and leads to more stable beneficial microbial communities, especially in severe drought, thus providing more accurate predictions to preserve soil diversity under unfavorable environmental conditions.

“…Both the root quantity and the root quality seemed to affect soil C storage as a major factor controlling root decomposition (Bonanomi et al 2021). In this young agroforestry system, the roots in Crop-1 m and in the UVS were richer in lignin than those in Crop-4 m. Furthermore, we observed that the soil C stocks increased with an increasing root lignin:N ratio, suggesting that root chemical recalcitrance increases soil C storage because of the slower root litter decomposition rate (Moorhead et al 2014;Bonanomi et al 2021) in UVS than in Crop-4 m (Abbasi Surki et al 2021).…”

Purpose In agroforestry systems, the root distributions and properties of the annual and perennial vegetation are poorly known, although they are recognized for fostering soil carbon (C) stocks through annual root-derived C inputs and by altering microbial activity. This study aimed to evaluate the potential contribution of roots from the understory vegetation strip (UVS) and the crop to top-and subsoil C stocks (0-100 cm) to a 3-year-old agroforestry system of the alley-cropping type. Methods Root biomass, chemical composition, functional traits and anatomical structure were assessed in parallel to a characterization of soil physicochemical

“…Moreover, factors such as organic material quality or soil physical structure also influence the qCO 2 (Spohn and Chodak, 2015). In agroforestry systems, litterfalls are frequently ideal substrates for microbial activities (Surki et al, 2021). The soil microbes regulate C and N cycles in the soil, stimulated by accumulation of the litterfalls and organic materials (Li et al, 2020;Ma et al, 2022).…”

Pruning and fertilization practices plays an important role in coffee plantation, used to maintain soil quality and coffee productivity. However, the impact of pruning and fertilization practices on soil microbial activity under coffee-based agroforestry are poorly understood. The aimed of this study was to analyze the response of soil microbial properties (i.e., soil microbial biomass C (SMBC) and soil respiration rates (SR)) to pruning and fertilization management in coffee-based agroforestry in UB (Universitas Brawijaya) Forest. A split-plot design with eight treatments and three replications were used in this experiment. The main-plot factor consisted of two types of pruning (Pruning and Bending), and the sub-plot factor consisted of four types of fertilization (i.e., no fertilizer (NF), 100% chicken manure (MN), 50% chicken manure + 50% NPK-inorganic (MN+NPK), and 100% NPKinorganic (NPK)). The result showed that there was a significantly different (p<0.05) in the soil microbial biomass C and soil respiration after the application of fertilizer. The addition of chicken manure (MN and MN+NPK treatment) could enhance the soil microbial biomass and soil respiration, compared to the NF treatment under different pruning practices. The level of soil pH in MN were highest and significantly different with NPK treatment, showed that the application of chicken manure had a potential to neutralize the soil acidity. Metabolic quotient (qCO 2 ) showed highest in the NF treatment as compared to the other treatments. The soil respiration had positive correlation (p<0.05) with SMBC, while SMBC had negative correlation (p<0.01) with qCO 2 .
