Recommendations for Better Soil Health
Introduction
Soil health is a critical component of sustainable agriculture, influencing crop productivity, environmental quality, and ecosystem sustainability. This report outlines ten actionable recommendations to enhance soil health, drawing from recent research and advancements in agricultural practices.
Recommendations and Actions
1. Adopt Site-Specific Nutrient Management
Implementing site-specific nutrient management can significantly improve fertilizer use efficiency and reduce environmental impacts. This approach tailors nutrient applications to the specific needs of different fields, optimizing crop uptake and minimizing nutrient losses
1.
2. Utilize Controlled-Release Fertilizers
Controlled-release fertilizers provide a steady supply of nutrients over time, matching the crop's nutrient demand more closely than conventional fertilizers. This method reduces nutrient leaching and volatilization, enhancing nutrient use efficiency and soil health
2.
3. Incorporate Organic Manures and Compost
Integrating organic manures and compost into soil management practices can improve soil structure, increase organic matter content, and enhance microbial activity. This practice supports long-term soil fertility and health
3.
4. Implement Conservation Agriculture Practices
Conservation agriculture, including no-till farming, crop rotation, and cover cropping, helps maintain soil structure, reduce erosion, and enhance soil organic matter. These practices contribute to improved soil health and resilience
4.
5. Adopt Water-Saving Irrigation Techniques
Techniques such as alternate wetting and drying (AWD) and aerobic rice systems can reduce water usage and improve soil aeration. These methods help maintain soil health by preventing waterlogging and reducing methane emissions
5.
6. Use Biostimulants and Integrated Pest Management (IPM)
Biostimulants can enhance plant growth and soil health by improving nutrient uptake and stress tolerance. Combining biostimulants with IPM strategies can reduce reliance on chemical inputs, promoting a healthier soil ecosystem
6.
7. Enhance Soil Biodiversity
Promoting soil biodiversity through practices such as reduced tillage, organic amendments, and diverse crop rotations can improve soil structure, nutrient cycling, and resilience to pests and diseases. Soil fauna, such as earthworms and beneficial insects, play a crucial role in maintaining soil health
7.
8. Monitor and Manage Soil pH
Maintaining an optimal soil pH is essential for nutrient availability and microbial activity. Regular soil testing and appropriate amendments, such as lime or sulfur, can help manage soil pH and improve soil health
8.
9. Implement Precision Agriculture Technologies
Precision agriculture technologies, such as GPS-guided equipment and remote sensing, can optimize input applications and monitor soil conditions in real-time. These technologies enhance resource use efficiency and support sustainable soil management
9.
10. Promote Farmer Education and Training
Providing farmers with education and training on sustainable soil management practices is crucial for widespread adoption. Extension services, workshops, and demonstration projects can help farmers understand and implement practices that improve soil health
10.
Conclusion
Improving soil health requires a multifaceted approach that integrates advanced nutrient management, conservation practices, organic amendments, and precision technologies. By adopting these recommendations, farmers can enhance soil fertility, productivity, and sustainability, contributing to a more resilient agricultural system.

11. Soil health is also crucial for sustainable agricultural production, ensuring competitive and sustainable yields
12.
3. Soil Health Indicators
The SoilHealthDB includes 42 soil health indicators and 46 background indicators that describe factors such as climate, elevation, and soil type 13 | Scientific Data - Nature" https://www.nature.com/articles/s41597-020-0356-3. Indicators span physical, chemical, and biological domains, supporting practices for enhancing soil functions 14. | | |
4. Soil Health Assessment Frameworks
A bioregionally-adapted approach to soil health assessment involves using a common set of soil health indicators relevant to a particular region’s soils and production systems
15. An open soil health assessment framework aggregates multiple soil properties into soil health scores, highlighting spatial distribution and limitations in soil health
16.
5. Soil Health and Human Health
The Soil Health Institute (SHI) released a report in 2019 on the connections between soil health and human health, including recommendations for better understanding these relationships
17.
6. Soil Health Policies and Strategies
The European Commission's proposal for a renewed EU Soil Strategy aims for all soil ecosystems in the EU to be in a healthy state by 2050, anchored in the EU's 2030 Biodiversity Strategy, Climate Adaptation Strategy, and EU Action Plan
18. The UK Government is advised to set out long-term plans for more ambitious soil health measures by 2026
19.
7. Conservation Agriculture and Soil Health
Conservation agriculture (CA) practices are being adopted worldwide to address challenges such as declining factor productivity, deteriorating soil health, water scarcity, and climate change
20.
8. Conclusion
Soil health is a multifaceted issue that requires a comprehensive approach involving assessment frameworks, policy initiatives, and sustainable agricultural practices. Continued research and policy support are essential for maintaining and improving soil health globally.
