Regenerative agriculture is a collection of practices and principles focused on keeping soil, water, animals, native plants, and people healthy for future generations. These methods aim to maintain or even increase productivity and profitability while building resilience in production systems.

 

This ecological approach encourages farmers to think holistically, always seeking ways to improve. It recognises that every farm is unique and faces its own challenges, but the goal is to enhance the health of both our farms and the communities around them. Regenerative Agriculture has proven difficult to define, but the following information will aim to provide a better understanding of the topic.


In Practice

Rotational Grazing: Rotational grazing is a system where animals are moved frequently to allow plants to rest and regrow. This prevents overgrazing and keeps the soil covered, which reduces erosion and helps the land stay productive. Frequent moves also ensure that manure is spread evenly, adding natural nutrients to the soil, and promoting stronger pasture growth.  

 

No-Till or Reduced-Till Farming: Tilling can break down soil structure, making it prone to erosion from wind and water. It also reduces the soil’s ability to hold water, which can be especially harmful during droughts. No-till or reduced-till farming addresses this by planting seeds directly into the soil left from the previous crop without heavy tilling. This keeps the soil structure intact, helps it retain moisture, and increases organic matter, all of which contribute to healthier soil that’s better protected against erosion.

 

Crop Rotation: Planting the same crops year after year can deplete soil nutrients and attract more weeds and pests. By rotating different crops, such as alternating between nitrogen-fixing plants like soybeans and nitrogen-demanding crops like corn, farmers can naturally replenish soil nutrients and reduce the need for synthetic fertilisers. This practice also disrupts pest cycles and helps control weed growth. Additionally, keeping the soil covered year-round with cover crops prevents erosion, boosts organic matter, and improves water retention.

 

Data-Driven Precision Farming: Precision farming uses digital tools like soil sensors to customise the application of fertilisers and crop protection products. This targeted approach reduces waste and ensures that resources are used exactly where and when they’re needed, leading to more efficient and effective results.

 

Livestock Integration: Introducing animals like cows, sheep, goats, chickens, and pigs into crop systems can boost soil health. As the animals graze, they naturally fertilise the land by turning plants into nutrient-rich manure. This adds valuable organic matter to the soil, improving its structure and promoting long-term soil health.

 

Forest Buffers/Riparian Zones: Buffers are areas along stream banks that are planted with native trees, shrubs, or grasses. They act as natural filters, slowing water flow and preventing sediment runoff into waterways. Additionally, installing streamside fencing, such as exclusion fencing, helps keep livestock and their waste away from these water sources, protecting water quality.

Key Benefits

  • Healthier Soil: Using methods like reducing tillage, planting cover crops, rotating crops, and integrating livestock can boost soil health and structure. This creates stronger, healthier soil that can better handle extreme weather, leading to better pastures and crops.

     

  • Greater Climate Resilience: Healthier soil retains water more effectively, providing resilience during droughts and improved water absorption during wet seasons, combating risk of slips and erosion.

     

  • Improved Water Quality and Ecosystem Health: Establishing riparian zones and stream fencing helps protect waterways by reducing sediment runoff and preventing contaminants from entering.

     

  • Definition Flexibility: Unlike organic farms, regenerative agriculture lacks rigid guidelines, making it adaptable to diverse farm contexts. This flexibility allows farmers to tailor practices to their unique conditions and goals.

 

  • Balancing Productive and Natural Landscapes: Regenerative practices aim to improve natural landscapes while boosting farm productivity. Healthier soil enhances land quality, which in turn benefits both crop yields and animal health.

     

  • The Future of Farming: Farmers are deeply invested in the long-term success of their operations. As regenerative agriculture continues to be researched and refined, it may serve as a key tool for ensuring effective land use for future generations.

     

  • Reduced Need for Synthetic Fertilizers: Healthier soil and diverse crop rotations decrease the need for synthetic fertilizers, reducing input costs for farmers.

Key Challenges

  • Definition Discrepancy: The lack of a clear, standardised definition for regenerative agriculture can be confusing and challenging for farmers looking to adopt these practices.

     

  • Long-term Effects: While there is scientific support for regenerative agriculture's potential as a climate solution, the extent and durability of its benefits remain uncertain.

     

  • Adopting Regenerative Practices: Implementing regenerative practices often involves trial and error to identify what works best for each unique farm, which can be resource-intensive and may take significant time to yield positive results.

     

  • Effectiveness Across Regions: The benefits of regenerative practices are not universal. For instance, increased soil carbon sequestration may not be as impactful in regions like New Zealand, where soil carbon levels are already high.

     

  • Need for Evidence: Due to the lack of a clear definition, more evidence and scientific research are needed to validate the benefits and ensure that they are both effective and achievable universally.

Global Context

Farmers around the world are facing growing challenges due to unpredictable weather and increasing pressure to care for the environment. With the global population expected to reach 9.8 billion by 2050, it's more important than ever for farmers to find new ways to secure the future of farming.

One example is General Mills, a U.S. food company that aims to implement regenerative practices across its farmland by 2030. They’re focusing on five key areas: supporting the local economy, improving soil health, managing water use, protecting biodiversity, and promoting animal welfare. They’ve started pilot projects to test the impact of these methods on the ground.

Meanwhile, Ridgedale Farm in Sweden combines crops, livestock, and education to train the next generation of farmers. With only 120 frost-free days a year, they focus on rebuilding soil and ecosystems, proving that profitable, sustainable systems can work even in challenging environments.

 

Case Study: Great Barrier Reef

 
Virtual Fencing is used as an innovative tool to help protect the Great Barrier Reef by reducing sediment run-off in riparian zones. By using neckbands fitted on Wagyu-cross females, this technology allows farmers to subdivide paddocks and intensify grazing without physical fences. This enables more precise rotational grazing, which gives pastures time to rest and recover, stimulating healthier regrowth. As the pasture recovers, soil quality improves, leading to a reduction in sediment run-off into nearby waterways.

 

Preventing sediment from entering rivers and streams is crucial for maintaining water quality, which is vital in preserving the fragile ecosystems of the Great Barrier Reef. This method not only supports better environmental stewardship but also aligns with regenerative agriculture principles, which emphasise restoring soil health, improving biodiversity, and creating sustainable farming systems.
