Abstract :

[en] Despite growing interest in silvoarable agroforestry systems (SAFs) as agroecological solutions for sustainable agriculture, their impacts on soil biological health remain poorly synthesised and inconsistently assessed in Western Europe. This study addresses this gap through an updated review and meta-analysis, highlighting the spatial and temporal dynamics of SAFs' effect on soil biological health and identifying key research needs. We proposed a revised definition of soil biological health as: “The soil's ability to sustain numerous and diversified organisms, promoting a wide range of ecosystem services and/or efficient crop development, in close interaction with its physical and chemical components”. A bibliographical synthesis was carried out to summarise how the above- and belowground tree components, together with the understory vegetation strip, influence soil biological health. Meta-analysis based on 38 publications (1253 comparisons and 19 indicators of soil biological health) revealed a significant overall positive effect of SAFs compared to crop control plots on soil biological health (effect size = 0.39, 95% confidence interval [0.22–0.57], p < 0.001). Effect sizes increased with stand age and declined with distance from the tree row. Notably, 86% of the measurements were conducted within the top 30 cm of soil, reflecting a common assumption that this layer sufficiently represents soil biological health. Within the 0–30 cm soil layer, SAFs significantly increased soil organic matter content (p < 0.001), earthworm abundance (p < 0.001), litter-feeding macrofauna (p < 0.01) and arbuscular mycorrhizal fungi (p < 0.05), while reducing soil bulk density (p < 0.001). However, knowledge gaps remain concerning the effects of SAFs on mesofauna, microbial activity, young stands, and deeper soil layers in Western Europe. Finally, the diversity of indicators highlights the need for integrative indices that synthesise multiple biological parameters into aggregate scores. Further research is also required to quantify all ecosystem services provided by improved soil biological health under SAFs.
