At present, there are 7 carbon sink methodologies directly related to agriculture in the list of methodologies that have been filed by the state, namely: conservation tillage emission reduction and sink increase project methodology, reduction of methane emissions through adjustment of water supply management practices in rice cultivation, reduction of the use of synthetic nitrogen fertilizer through the use of inoculation bacteria in the recycled planting of soybean-grass in acidic soils of existing farmland, and greenhouse gas emission reduction methodology for biogas production and utilization of bio-natural gas from biogas generated by manure management system. Ruminant Reduction Project Methodology, Livestock and Poultry Manure Compost Management Emission Reduction Project Methodology, Methane from Household or Small Farm Agricultural Activities**.

However, agricultural carbon sinks can be reaped as carbon offset projects.
