Soil restoration increases soil health across global drylands: A meta‐analysis

چکیده
Soil degradation is one of the greatest environmental issues our planet faces today, with over 33% Earth's soils currently degraded. Drylands are especially vulnerable to soil given their history intensive land use and desertification. Active restoration has been identified as a leading strategy combat promote ecosystem recovery. However, soil-based dryland techniques have shown varying success, potentially due lack understanding ecological contexts in which treatments most beneficial. To improve how best active restore degraded drylands, we conducted global meta-analysis treatment effectiveness at improving health across gradients. The metrics analysed were aggregate stability, bulk density, moisture, organic carbon (SOC), nitrogen, mycorrhizal colonization basal respiration. For this collected 155 publications, yielding 1403 unique studies spanning six continents. We found that overall, had beneficial effect on all measures ranging from +11% increase density (inverse) +6967% colonization. Aridity texture greatly influenced for certain metrics. Specifically, was be effective arid, fine-textured mesic, coarse-textured soils. Additionally, amendments increasing SOC, while fungi inoculation Synthesis applications: Our findings indicate an tool provide information optimal site conditions aspects health. This could help inform decision-making, thus outcomes, worldwide.

[1] Understanding and accurately predicting the fate of carbon and nitrogen in the terrestrial biosphere remains a central goal in ecosystem science. Amino acids represent a key pool of C and N in soil, and their availability to plants and microorganisms has been implicated as a major driver in regulating ecosystem functioning. Because of potential differences in biological diversity and litter...

AIM Geographic, climatic, and soil factors are major drivers of plant beta diversity, but their importance for dryland plant communities is poorly known. This study aims to: i) characterize patterns of beta diversity in global drylands, ii) detect common environmental drivers of beta diversity, and iii) test for thresholds in environmental conditions driving potential shifts in plant species co...

Soil bacteria and fungi play key roles in the functioning of terrestrial ecosystems, yet our understanding of their responses to climate change lags significantly behind that of other organisms. This gap in our understanding is particularly true for drylands, which occupy ∼41% of Earth´s surface, because no global, systematic assessments of the joint diversity of soil bacteria and fungi have be...
