Co-incorporation of hydrotalcite and starch into biochar-based fertilizers for the synthesis of slow-release fertilizers with improved water retention
| 1. | A new biochar fertilizer was developed by incorporating hydrotalcite and starch. |
| 2. | HS-BCF exhibited better water-retention and slow-release performance than BCF. |
| 3. | The nutrient release of HS-BCF was diffusion and relaxation-controlled mechanism. |
| 4. | The enhanced P durability of HS-BCF was partially due to the binding of hydrotalcite. |
