Utilizing waste compost in the rice-wheat cropping system is a sustainable strategy to enhance atmospheric CO2 capture. The process involves decomposing organic waste materials to create nutrient-rich compost. During rice cultivation, this compost is incorporated into the soil, improving its structure and fertility. Healthy rice plants absorb more CO2 during photosynthesis, aiding in carbon capture. In the subsequent wheat phase, the enriched soil supports robust wheat growth, further sequestering carbon. Additionally, the compost enhances soil organic carbon content, acting as a carbon sink and promoting long-term carbon sequestration. This approach not only captures CO2 effectively but also promotes sustainable agriculture through organic waste recycling, enriching soil health, and ensuring the system's long-term fertility.
