Agroforestry is a system of land utilization that describes trees with different crops fused in a single area for farmers' net income. One or more agroforestry practices in one particular area usually have biological, environmental and economic interaction whilst the main aim of the AFS is not only economic benefits but also modern studies show that AFS could be used as a prime source carbon pool. Up to 12-228 ton ha-1, with an average of 95 ton ha-1, can be stored via the AFS. Agroforestry systems with different trees can deal with climate change more efficiently and sequester more carbon. Trees with crops can raise the carbon stocks to several folds compared to monocrop systems. For example, In an agrisilvicultural system, 34.61 ton ha−1 compared to 18.74 ton ha−1 can be reserved in a monocrop system in order to meet the CO2 targets anticipated at Kyoto while simultaneously maintaining sustainable farm production and preventing further deforestation, integration of agricultural practices and systems in C Sequestration and C trade projects can be highly useful. Pakistan is a low middle income with an average annual rate of growth of 216.6 million people. Agroforestry has a very important role and is a key part of Pakistan's daily life, particularly rural people Agroforestry is an important timber and fuelwood source, with 70 percent of the urban and 97 percent of the rural domestic fuel wood being the main energy source in Kyber Pakhtunkhwa for centuries. In Khyber Pakhtunkhwa agroforestry is practiced in various models and shapes from the protection of naturally growing trees to the artificial cultivation of trees on agricultural lands. The Soil Organic Matter (SOM) is estimated to store 1500 Pg (1 Pg=1015 g) C to a depth of 1 m. To calculate soil organic carbon it is assumed that total organic matter contains 58% organic carbon contents or a relation i.e. organic carbon=SOM% multiply by 0.58 statistical Analysis were conducted using The jamovi project (2021). jamovi. (Version 1.6). The mean value of SOC for agri silviculture system is 2.65 while that of Silvo pastoral system is 2.23. The means of two systems are different from eachother. The mean value of SOM for agri silviculture system was found to be 4.56 and for Silvo pastoral system it is 3.84. Our results show that soil Organic carbon had an inverse relationship with soil pH. High density of carbon in agricultural Lands including agroforestry is related to the high tree diversity that increases plant production hence increased biomass. Litter fall also contributes to C stock accumulation in Soil. It is the most important known pathway connecting vegetation and soil, and is a good Indicator of aboveground productivity.
