Impact of crop type (Wheat and Pistachio) and soil properties (Depth, texture and nitrogen content) on the amount of carbon sequestration

The type of land use, the amount of vegetation and their management, play an important role in the carbon sequestration capacity of the ecosystem. Therefore, in order to estimate soil carbon sequestration over time affected by vegetation type, in Gonabad city, first using remote sensing data of ETM and TM satellite images, land use map of the city for the years 1387 and 1397 based on the maximum probability classification method. Similarity was provided. Vegetation index was also calculated for the images. In order to estimate the amount of soil carbon sequestration in the two years studied and to investigate the relationship between depth, texture and percentage of soil nitrogen with the amount of carbon sequestration in pistachio and wheat, soil test results and GPS points of these uses were prepared using independent t-test And regression relations data analysis was performed. The results showed that different land uses with different vegetation levels have different effects on soil carbon sequestration. So that the total amount of soil carbon sequestration in pistachio orchards in 1397; It had the highest rate of carbon sequestration per hectare. The study of the relationship between depth, texture and percentage of soil nitrogen with carbon sequestration showed that there is a positive relationship between the percentage of nitrogen, silt and soil clay and a negative correlation between sand and carbon sequestration.
