Analyzes global soil health research trends and proposes a microbiome-based framework for assessment, indicating a shift towards biologically driven research.
Key Points
The aim is to examine trends in soil health research and propose a microbiome-based assessment framework.
Utilized a PRISMA-based methodology to combine data from various sources.
Evaluated trends in soil research from 1990 to 2025 focusing on thematic and regional patterns.
Developed a structured microbial indicator framework based on twelve functional microbial groups.
Identified a sustained increase in soil-related research, with nutrient management and soil degradation as dominant topics.
Noted rapid growth in soil microbiome research and carbon sequestration since 2015.
Found significant regional disparities, with research concentrated in Asia, Europe, and North America.
