Abstract
The current studies show that the agroforestry system could be used as a prime source of carbon pool. Up to 12-228 tons ha-1, comprising a mean of 95 tons ha-1, can be stored via the agroforestry systems. Agroforestry systems with different trees can deal with climate change more efficiently and sequester more carbon. The crops that consist of trees can raise stocks of carbon to many folds while making in comparison with the single crop system. 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 bulk density of the silvopastoraloral system is 1.346 gm/cm3 which is more than the agri silvi system which is found to be 1.251 gm/cm3. The lower bulk density in the Agri Silvi system showed less compaction of soil resulting in enhanced vegetation. The bulk density was founded with the help of soil particle analysis. 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% multiplied by 0.58 statistical Analyses was conducted. Higher SOC indicates Agri Silvi system shows fertility of the soil. The mean value of soil organic carbon for agri silviculture system is 2.65 while that of the Silvopastoral system is 2.23. The mean value of SOM for agri silviculture system was found to be 4.56 and for Silvopastoral system it is 3.84. The percentage of SOM was determined with the help of loss on the ignition method. The higher SOM in the agrisilvi system helps in an increase in the productivity of the soil. The enhanced density of carbon in the fields of agriculture particularly depends upon the diversity of high trees that results in an enhancement of biomass and the production of plants. In soil carbon stock the fall of litter also plays its role. In above-ground production, it plays a prominent role in the connection of soil with vegetation.
