Assessing soil carbon sequestration capacity of cropland’s with cool farm tool under organic agriculture

Abstract

The efficient use of nutrient is essential to achieving a number of Sustainable Development Goals (SDGs), including tackling climate change, decreasing poverty, and ending hunger. We also investigated how the soil organic carbon and the levels of nitrogen as well as phosphorus relates to one another. We used a program called the “cool farm tool,” which is already licensed by the IPCC, to carry out this investigation. One farmer was interviewed at each of the seven locations that were chosen in order to collect input data, and two hundred ten soil samples were examined in a lab to determine the soil pH as well as soil organic carbon content. The results showed that most of the discovered areas with low soil organic carbon had great potential for future carbon sequestration. Additionally, there was a range of 307.09–390.04 t ha⁻¹ (mean ± SD as 348.56 ± 0.78) for the total nitrogen concentration and 13.98 to 21.33 t ha⁻¹ (mean ± SD as 17.65 ± 0.04) for the total phosphate concentration. In addition, the total amount of soil organic carbon content was 1.39 to 0.96% (mean ± SD as 1.17% ± 0.01). The results of this study revealed that the tool was most effective for measuring soil carbon sequestration, nitrogen and phosphorus in crop land, which has the fewest uncertainties and data gaps. The program will therefore play a crucial role in efforts to mitigate climate change impacts.
