Introduction
Standard Background and Significance
As the first special evaluation standard for farmland carbon sequestration technology in my country, this standard fills the gap in technical evaluation in the field of agricultural carbon sinks. The standard is based on the test data of equipment such as soil organic matter meter, and constructs an evaluation system with four dimensions: technical level, practicality, environmental benefits, and economic benefits.
Core evaluation index system
| First-level index | Second-level index | Key parameters |
|---|---|---|
| Technical level | Annual change rate of soil organic matter | NY/T 1121.6-2006 determination |
| Annual change rate of biomass | Dry matter weight method | |
| Innovation | Comparison of patents/technical features | |
| Practicality | Promotion stage | Demonstration/small-scale/large-scale |
Carbon sequestration calculation method
Case: North China Plain Straw Return to Field Project
Use formula (5) to calculate the carbon sequestration in a five-year period:
ΔCsoil = (SOC5 - SOC0) × 1.32g/cm³ × 30cm × 100hm² × 0.58 × 0.1
The measured organic matter content increased from 25g/kg to 28g/kg, and the annual carbon sequestration reached 68.4t CO2e
Implementation suggestions
- Preferably use Laser particle size analyzer and other equipment to ensure data quality
- Weight setting needs to be combined with local farming system (see Appendix B default values)
- The monitoring period is recommended to be ≥ 3 crop growing seasons
