Supporting evidence — 5 representative gaps

• Light grazing enhances microbial-mediated nitrogen transformation in desert steppe soils (2025) · BMC Plant Biology · cited 7× · doi

  AIMS: Soil microorganisms play a central role in nitrogen transformation and availability, yet their regulatory functions in mediating nitrogen transfer between soil and plants under long-term grazing remain poorly understood.

• Exploratory Flux Pulses and Emerging Trade-Offs in a Semi-Arid Lettuce Experiment: Plant and Nitrogen Effects on GHG and NH3 Emissions (2025) · Horticulturae · cited 2× · doi

  Further work integrating microbial data would be required to clarify the mechanisms underlying this response. Further research combining high-frequency flux measurements with targeted microbial and plant physiological analyses is needed to quantify the relative contributions of these mechanisms in semi-arid agroecosystems. Further research is necessary to delineate the dynamics of NH3 flux in vegetated soils and the factors governing the interactions with plants and soil properties.

• Nitrogen Fertilization Effects on Soil Bacterial Communities, Nitrogen-Cycling Genes, and Wheat Yield Across Different Soil Types in the North China Plain (2025) · Microorganisms · cited 5× · doi

  The impact of nitrogen fertilization on bacterial communities and wheat yield across different soil types is poorly understood. The relationships among soil, microbes, and nitrogen-cycling functional genes are not well understood.

• 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.

• Microbial functional guilds and genes are key to explaining soil nutrient cycling alongside soil and plant variables (2025) · Ecosphere · cited 4× · doi

  Abstract Microbes play central roles in soil nutrient cycling; yet, a limited range of microbial community characteristics have been used to explain ecosystem nutrient cycling rates, and their importance relative to plant and abiotic factors remains unclear.
