Cultivated land carbon sink

The cultivated land carbon sink is an important part of the cultivated land carbon sink and is interconnected and interacts with the carbon sinks in other ecosystems such as forests and grasslands. Globally, cultivated land carbon sink is a relatively active carbon pool, and its carbon sink capacity is affected by many factors, such as climate change, land use patterns, agricultural management measures, etc. Therefore, adopting scientific and reasonable agricultural management measures, such as conservation tillage, returning straw to fields, increasing organic fertilizers, etc., can promote photosynthesis of plants and accumulation of soil organic matter, and improve the carbon sink capacity of cultivated land.
However, the development of cultivated land carbon sinks faces some challenges and opportunities. As the global population grows and agricultural production develops, more sustainable agricultural management models need to be explored to balance the relationship between agricultural production and environmental protection. At the same time, as the carbon trading market continues to improve, cultivated land carbon sinks will also become an industry with economic value, providing farmers with new sources of income and promoting rural economic development. Therefore, it is necessary to further research and promote related technologies and models of cultivated land carbon sequestration to achieve sustainable development of agricultural production and respond to global climate change.
