Sequestering atmospheric CO2, through cultural management is amongst effective practices toward sustainable agriculture. This field study was conducted to employ optimized cultural practices in diversified production systems to attain improved soil chemical properties and carbon sequestration with a focus on wheat production over two cropping seasons (2019-2020 and 2020-2021) at Karaat plain in Taybaad. The experimental factors included planting system with four levels (fallow-wheat, mung bean-wheat,, corn-wheat, and wild rocket-wheat,) and nitrogen fertilizer in three levels () were arranged as a factorial trial based on RCBD. Soil chemical properties such as acidity, organic carbon, total nitrogen, as well as available phosphorus and iron of the soil were measured. Carbon sequestration was measured through subtracting the carbon content at the beginning of the experiment and end of it. The results showed that the cropping system had a significant effect on the soil chemical properties, also nitrogen fertilizer levels had a significant effect on soil organic carbon properties, total soil nitrogen and carbon sequestration. The results showed that changes in soil organic carbon and nitrogen are mainly responsible for changes in soil chemical properties. Moreover, crop rotation and eliminating the fallow period had significantly affected the sequestration of atmospheric CO2.
