Biochar is increasingly recognised as a powerful tool for improving soil health, supporting regenerative farming, and reducing reliance on synthetic inputs. When incorporated into soils or blended with organic materials such as farmyard manure, biochar helps create a more balanced and resilient soil ecosystem.

Biochar has a highly porous structure, providing an ideal habitat for beneficial soil microorganisms while also improving soil aeration and water retention. This structure allows soils to hold nutrients more effectively, reducing nutrient loss and improving plant access to essential elements for growth.

When used as part of a regenerative soil management strategy, biochar can enhance soil fertility, strengthen plant health, and support long-term carbon storage in agricultural soils.

 

Biochar and Organic Manure

One of the most effective ways to apply biochar is by integrating it with farmyard manure or bedding systems before spreading it onto fields. This approach allows the biochar to absorb nutrients such as nitrogen during storage, preventing them from being lost through volatilisation or leaching.

Research and practical farm experience have shown that combining biochar with manure can significantly improve soil conditions. Biochar helps stabilise nutrients within organic matter and releases them slowly once applied to the soil, providing a steady nutrient supply for crops and grassland.

This process also supports beneficial microbial activity, which plays a key role in nutrient cycling and soil structure.

 

Observed Soil Health Improvements

Practical on-farm trials have demonstrated measurable improvements in soil quality where biochar has been used alongside manure and regenerative grazing systems. Over a four-year period, soil testing showed:

• Soil pH improving from 6.6 to 7.1

• Soil organic carbon increasing significantly

• Available phosphate levels increasing by over 60%

• Total exchange capacity rising by around 68%

These improvements indicate stronger soil fertility, enhanced nutrient cycling, and improved soil structure. Higher organic carbon levels are also associated with better water-holding capacity and increased biological activity in the soil.

Improved soil conditions can lead to stronger pasture growth, increased resilience during challenging weather conditions, and reduced reliance on external fertiliser inputs.

 

Supporting Plant and Animal Health

Biochar can also play an important role within livestock systems. When used in bedding, biochar absorbs moisture and nitrogen from manure, helping to reduce ammonia emissions and create a healthier environment for animals.

Manure enriched with biochar contains more stabilised nutrients when applied to land, improving soil biology and plant growth while reducing nutrient runoff or leaching. Farmers using this approach have reported improved pasture productivity and healthier livestock systems overall.

 

Ongoing Soil Monitoring

Initial soil test results after four years of biochar use showed significant improvements in soil organic carbon, nutrient availability, and overall soil biology. However, this work is ongoing.

Further soil testing and monitoring continue to track long-term changes in soil health, productivity, and carbon levels. By continuing to measure results over time, we aim to better understand the long-term role biochar can play in regenerative agriculture and sustainable land management.
