The DeepHorizon project is pioneering advancements in soil science by integrating cutting-edge technologies to study and manage the subsoil. 

Among its most innovative tools are the BODIUM and ECOSYS models, which provide groundbreaking insights into the processes that occur beneath the soil surface. These technologies are instrumental in addressing global challenges such as climate change, sustainable agriculture, and soil resource preservation.

The BODIUM Model: Understanding Carbon and Nutrient Dynamics

The BODIUM model focuses on analyzing the dynamics of carbon and nutrients in the subsurface. It is a critical tool for understanding how human activities, such as intensive farming, impact soil health and its ability to store carbon.

• Primary Purpose: To simulate how biogeochemical processes in the subsoil affect carbon stability and nutrient availability for plant growth.
• Key Features:
  • Predicts the soil’s capacity to sequester carbon under varying climate scenarios.
  • Evaluates how agricultural practices influence nutrient balance and soil fertility.
  • Identifies sustainable farming methods that maximize productivity without depleting soil resources.
• Application: BODIUM is deployed across experimental sites in the project to create tailored scenarios, enabling farmers and policymakers to make informed, data-driven decisions.

The ECOSYS Model: A Comprehensive View of Soil Ecosystems

While BODIUM hones in on carbon and nutrients, the ECOSYS model takes a broader perspective, simulating the entire functioning of soil ecosystems. This tool is essential for understanding the interactions between the physical, chemical, and biological properties of the subsoil.

• Primary Purpose: To evaluate how factors such as water, temperature, and plant roots interact and influence subsurface processes.
• Key Features:
  • Simulates water flow within the soil, including drainage, retention, and filtration.Models root growth and its interaction with soil microorganisms.
  • Predicts how changes in climate or land management practices impact essential soil functions.
• Application: ECOSYS supports the design of soil management strategies that optimize water use and promote resilient ecosystems.

Why These Models Matter

The integration of BODIUM and ECOSYS into the DeepHorizon project has a profound impact on how we understand and manage the soil. 

These models shed light on the vital role subsurface layers play in processes like carbon storage, soil fertility, and water regulation, offering a much deeper insight into how these systems function. For farmers, they provide practical solutions to improve efficiency—helping to optimise fertiliser use and irrigation techniques, which not only boosts productivity but also reduces environmental harm. At the same time, these tools are essential for addressing climate challenges, as they predict how the subsurface will respond to extreme weather, guiding the development of strategies to protect and adapt soil systems for the future.

The Transformative Potential of BODIUM and ECOSYS

Together, these models represent a revolutionary approach to soil science. Not only do they provide a detailed analysis of subsurface processes, but they also translate that information into practical solutions for farmers, policymakers, and researchers. Their ability to process vast datasets and deliver accurate predictions marks a turning point in how we understand and manage this critical resource.

Conclusion

The integration of BODIUM and ECOSYS into the DeepHorizon project carries significant implications for soil science and its practical applications. These models provide valuable scientific insights by deepening our understanding of how subsurface layers contribute to critical processes such as carbon cycling, soil fertility, and water regulation. For sustainable agriculture, they offer actionable tools that empower farmers to optimise their practices, from precise fertiliser application to more efficient irrigation strategies, ultimately enhancing productivity while minimising environmental impact. Furthermore, these models play a crucial role in building climate resilience by predicting how the subsurface responds to extreme weather events, enabling the development of effective strategies to adapt and safeguard soil resources under changing climatic conditions.
