Supporting evidence — 8 representative gaps

• Responses of soil microbial metabolism, function and soil quality to long-term addition of organic materials with different carbon sources (2024) · Biochar · cited 62× · doi

  However, there is limited research systematically and comprehensively exploring the response of soil microbiota and the changes in soil metabolomics after the addition of two different carbon source amendments to the soil, and the differential mechanisms of soil metabolomics between them remain unclear.

• Effects of tree species mixing on soil microbial community structure in Karst regions of Southwest China (2026) · Frontiers in Microbiology · doi

  There is a lack of research on the effects of tree species configuration on soil microbial communities in Karst regions of Southwest China. The study aims to address this gap by investigating the effects of tree species mixing on soil microbial community structure.

• Soil carbon dynamics shape bacterial communities across grassland and agricultural soils with implications for phosphorus (2026) · Frontiers in Soil Science · doi

  The role of phosphorus in shaping bacterial community structure remains underexplored. There is a need to understand the impact of land-use changes on soil microbial communities.

• Soil microbial diversity alters soil microhydrology through extracellular polymeric substance production (2026) · bioRxiv · doi

  To date, the role that microbes and their diversity play in soil hydrology has been severely understudied, so this work aims to build ecological understandings of these systems.

• The illusion of diversity: sampling design drives conflicting estimates of soil bacterial richness (2026) · bioRxiv · doi

  Further studies are needed to evaluate the impact of sampling design on soil microbial diversity estimates in different ecosystems. The development of new sampling designs and methods for characterizing soil microbial diversity is needed. The use of individual cores and physically homogenized composite samples should be compared in different soil types and ecosystems.

• Influence of plant traits, soil microbial properties, and abiotic parameters on nitrogen turnover of grassland ecosystems (2016) · Ecosphere · cited 40× · doi

  Abstract Although it is known that multiple interactions among plant functional traits, microbial properties, and abiotic soil parameters influence the nutrient turnover, the relative contribution of each of these groups of variables is poorly understood.
