Soil organic carbon is considered as a key factor in soil fertility sustainability and soil ecosystem services. Soil organic carbon is also included in the United Nations Environment Program (UNEP) as one of the most important environmental issues and challenges on a global scale.
   Studies in Iran show that wheat grain yield increases by an average of 286 kg per hectare in exchange for an increase in per gram of organic carbon in per kilogram of soil. Significant increase in soil organic matter or preservation of high levels of organic matter is not simply possible. This process requires sustained effort, which includes two general approaches to addition organic matter to soils and reduction carbon loss. 
    Considering the climatic and soil conditions of the country, it seems that in the first stage, the operations that cause the loss of organic carbon in the soil should be controlled and then the increase of soil organic matter should be addressed.
 
 
Program Objectives

• Identifying appropriate solutions to preserve soil organic carbon in different climates of the country
• Providing solutions to increase the soil organic carbon of the country
•    Determining the carbon sequestration capacity of agricultural and horticultural soils of the country
• Determining the trend of soil organic carbon changes in different regions and climates of the country
• dentifying the impact of the use of fertilizers and soil amendments on increasing soil carbon and soil organic carbon storage
• Identifying the status of soil organic carbon of the country
