A new study shows that pairing biochar with lime tackles acidic soils and boosts productivity.

A three-year field study found that applying biochar and lime together increased peanut yields by up to 27% and farmer net income by 23% compared to lime alone.

The combination neutralized toxic aluminium, improved microbial activity by over 46%, and strengthened soil structure for long-term resilience.

Beyond yield improvements, the study also demonstrated a 53% reduction in future amendment requirements by the third year, proving that soil health, productivity, and profitability can go hand in hand when biochar is used strategically.

When it comes to implementing biochar at scale, success starts with the right trials and expert guidance.

As biochar is a highly variable material, its performance depends on factors such as feedstock, pH, and moisture content. Before committing to bulk purchasing, it’s essential to trial biochar for your specific use case to ensure optimal results.

🌳 How can biochar benefit trees here in the UK?

By improving soil structure, boosting nutrient availability, and enhancing water retention, biochar helps trees grow stronger and more resilient against stressors like drought and disease.

It also supports long-term carbon storage in woodlands and plantations, making trees healthier while contributing to wider sustainability goals.
