Research & Field Trials
Comprehensive field trial data demonstrating biochar's measurable impact on crop yields and soil health across both Field Crops and Horticultural Crops.
Maize, wheat and other grain crops showing consistent yield improvements in trials across Southern Africa.
| Type of Crop | Optimal Application Quantity | Yield Changes compared to Normal Fertilisers | Other Benefits |
|---|---|---|---|
| Maize | 5 MT / ha |
Field Trials: Grain Yield increased by up to 23%
Average: Grain Yield increased by around 10%
|
|
| Wheat | 5 MT / ha |
Field Trials: Grain Yield increased by up to 24%
Average: Grain Yield increased by around 9%
|
|
| Other Grains | 2 MT / ha |
Field Trials: Grain Yield increased by up to 31%
Average: Grain Yield increased by between 3% and 11%

In general, 5–10 MT application rates per Hectare provide the best Yield Improvements.
High-value crops including legumes, vegetables, tomatoes, vineyards and root crops demonstrating significant yield and quality benefits.
| Type of Crop | Optimal Application Quantity | Yield Changes compared to Normal Fertilisers | Other Benefits |
|---|---|---|---|
| Legumes | 1.6 MT / ha | Average: Yield increased by around 27% |
|
| Vegetables | 1.6 MT / ha | Average: Yield increased by around 15% |
|
| Tomatoes | 3 MT / ha | Average: Plant Growth increased by between 15% and 20% |
|
| Vineyards | 10 MT / ha | Yield increased by up to 29% after the second season |
|
| Tubers & Bulbs | 1.6 MT / ha | Average: Yield increased by around 9% | — |
In general, 5–10 MT application rates per Hectare provide the best Yield Improvements.
Research indicates that biochar application can significantly enhance tree growth, with studies showing an average 41% increase in growth rate, particularly during early growth stages. Australian field trials demonstrated that biochar-treated apple trees produced fruits weighing 20 grams each, without compromising firmness or sugar content. Similarly, trials in avocado orchards reported improved tree growth rates of up to 26% and an increase in fruit count by as much as 96%.
