Biochar Effects on Plant Growth in Ornamentals
University of Georgia Ornamental Specialist Ping Yu discusses the impact of biochar on plant growth in a four-part series.
Experiments were conducted on various plants, including tomatoes, basil, peppers, and petunias, using different percentages of biochar mixed with commercial substrates.
- Tomatoes were grown with sugarcane bagasse biochar (SBB) and 50% hardwood biochar (HB) mixed with a commercial peat moss-based substrate.
- Basil plants were grown with SBB and 50% HB mixed with a commercial peat moss-based substrate.
- Peppers were grown with mixed hardwood biochar (HB) mixed with a commercial peat moss-based substrate.
- Petunias were grown with sugarcane bagasse biochar mixed with a commercial bark-based substrate.
