Introduction

Soil biodiversity encompasses the vast diversity of organisms living within the soil, including bacteria, fungi, protozoa, nematodes, arthropods, and earthworms. These organisms are crucial for nutrient cycling, organic matter decomposition, soil structure maintenance, and plant health. Assessing soil biodiversity provides valuable insights into soil quality, ecosystem functioning, and agricultural sustainability. Soil biodiversity indicators are measurable biological, chemical, and physical parameters that reflect the abundance, diversity, and activity of soil organisms. Monitoring these indicators helps identify changes in soil health due to management practices, pollution, or climate stress [1,2].

Discussion

Biological indicators are the most direct measures of soil biodiversity. Microbial biomass, microbial respiration, and enzyme activity reflect microbial abundance and metabolic potential. Enzymes such as dehydrogenase, phosphatase, and urease indicate nutrient cycling processes and overall soil biological activity. Diversity indices derived from microbial DNA sequencing or nematode community analysis provide information on species richness and community structure, revealing potential imbalances caused by stress or intensive management [3,4].

Macrofauna, including earthworms, ants, and beetles, serve as valuable indicators of soil health. Their abundance, diversity, and behavior influence soil aeration, organic matter decomposition, and nutrient distribution. Earthworm population density and biomass, for example, correlate strongly with soil fertility and structure. Similarly, the presence of predatory or sensitive species can signal ecological integrity or disturbance.

Chemical and physical proxies can complement biological indicators. Soil organic matter, pH, nutrient content, and aggregate stability influence microbial activity and macrofaunal populations. High organic matter levels often support greater microbial diversity, while stable aggregates enhance habitat complexity for soil organisms. Integrating these measures with biological assessments provides a comprehensive picture of soil health [5].

Practical monitoring of soil biodiversity relies on combining multiple indicators. Standardized sampling, laboratory analyses, and field assessments allow comparisons across sites and management systems. Advances in molecular tools, such as metagenomics and eDNA analysis, have greatly improved the resolution and efficiency of biodiversity assessments, making it easier to track changes over time and under different agricultural practices.

Conclusion

Soil biodiversity indicators are essential tools for evaluating soil health, ecosystem resilience, and sustainable agricultural practices. Biological indicators, including microbial biomass, enzyme activity, and macrofaunal diversity, combined with chemical and physical proxies, provide a holistic assessment of soil function. Monitoring these indicators helps guide management decisions, detect environmental stress, and promote practices that enhance soil biodiversity. Protecting and enhancing soil biodiversity ensures productive, resilient, and sustainable agroecosystems for the future.
