Decoding soil health: essential indicators and management impacts

Area of Science:

• Agricultural Science
• Environmental Science
• Soil Science

Background:

• Rising global food demand exacerbates crop challenges due to soil degradation from chemical overuse and pollution.
• Non-judicious agricultural practices and environmental stressors threaten soil health and biodiversity, impacting food security.
• Sustainable agriculture requires collaborative efforts to address soil degeneration and ensure long-term viability.

Purpose of the Study:

• To review key variables for evaluating soil biodiversity, soil quality, and principles of soil health in sustainable agricultural systems.
• To highlight the importance of soil health for mitigating biotic and abiotic stresses and enhancing crop yield.
• To emphasize the role of microbial functions in nutrient cycling and soil remediation for agricultural sustainability.

Main Methods:

• Literature review of scientific publications on soil health, biodiversity, and sustainable agriculture.
• Analysis of stressors affecting soil biodiversity, including pollution, erosion, and climate change.
• Examination of management strategies promoting soil health, such as cover cropping, crop rotation, and organic matter addition.

Main Results:

• Soil health is fundamental to sustainable agriculture, ensuring food security and environmental preservation.
• Degenerative soil conditions, driven by chemical overuse and pollution, pose significant challenges to crop production.
• Microbial functions are intrinsically linked to soil health, influencing nutrient acquisition, decomposition, and remediation processes.

Conclusions:

• Adoption of sustainable practices like cover cropping, crop rotation, and integrated nutrient management is essential for improving soil health.
• Addressing threats to soil biodiversity through appropriate actions is critical for the sustainability of global agriculture.
• Understanding soil biodiversity, quality, and health principles is necessary for developing resilient and productive agricultural systems.
