Look into the soil to understand the benefits of NBS for soil

Soil profile demonstrations are vital because soil remains a "black box" for many farmers. While the benefits of Nature-Based Solutions (NBS) are real, they often lie hidden below the surface. By analyzing soil profiles, we make these benefits visible—providing farmers with clear, tangible proof that sustainable practices improve soil health and fertility. This hands-on approach shows how different management techniques affect root growth, microbial activity, and soil structure. Farmers often judge soil by surface signs, which can be misleading. Digging deeper reveals the true impact of practices, helping them see the changes beneath their feet. Soil profile demonstrations turn abstract science into visible, practical knowledge. By making the invisible visible, we empower farmers to make better decisions that support long-term sustainability.

Empirical understanding is key to changing farming practices. Soil profile demonstrations offer visual proof of improvements like better structure, more organic matter, and higher water retention. Farmers see how cover crops, reduced tillage, and manure improve soil health—benefits often hidden from the surface. By revealing real results, demonstrations bridge the gap between science and practice, building trust in NBS. Farmers observe changes in porosity, root growth, and biological activity, strengthening the link between practices and soil quality. This boosts confidence in adopting and maintaining sustainable methods. Soil profiles also support peer learning, encouraging collaboration and shared knowledge. When farmers can see the long-term value of NBS, they’re more likely to make informed choices that support soil, yield, and resilience—advancing the shift to regenerative agriculture.

Additional information

As part of a trans4num event, we conducted soil profile investigations to reveal variations within fields. By digging soil pits, we uncovered differences in composition—such as gravel layers in one area and rich, humus-rich topsoil in another—highlighting the importance of site-specific soil management. These hands-on demonstrations helped farmers directly observe the impact of Nature-Based Solutions (NBS) on soil health. Participants saw how sustainable practices affect root growth, soil stability, and water retention. This visual, tactile experience reinforced their understanding of how soil evolves under NBS and boosted confidence in applying regenerative practices. By linking soil characteristics to past management, farmers could better tailor their strategies for improved outcomes. Trans4num events serve as a platform for experiential learning, turning scientific knowledge into practical insight. These shared experiences strengthen peer learning, motivate sustainable action, and support the wider adoption of site-adapted regenerative agriculture.

Challenges

Implementing soil profile demonstrations can be difficult due to weather conditions like heavy rain or drought, which hinder accurate analysis. Timing is crucial, as farmers are busy during peak seasons. Engagement is also a challenge, requiring strong communication and clear evidence of benefits to gain farmers' interest.

Resources

Successful implementation requires good planning to ensure the right timing and location. Strong networks with farmers, advisors, and agronomists support knowledge-sharing. Expertise and proper equipment are essential, as soil scientists help interpret results and provide valuable recommendations for farmers.
