The significance of soil in the increasing carbon sequestration of urban
forests
Introduction:
Regarding the climate change, the priority can be bestowed to the fact that
soil hold pivotal position combat, such phenomenon through carbon sequestration, and the
lack of plants on land may havoc the loss of carbon.
Aim:
The aim of this study was to survey the effects of urban forests on soil carbon
sequestration in three stands including Robinia-Fraxinus, Robinia, and Cupressus.
Methods & Results:
The research was done at forest Pardisan Park in Tehran, and its
result was compared to a control land (barren land). With measuring organic carbon in
both 0-15 cm and 15-30 cm depth, the results demonstrate that carbon sequestration is
significantly the highest value (p<0.01) in the soil of mixed Robinia-Fraxinus stand (18.96
ton per ha) by comparison to Robinia and Cupressus (14.86 and 9.69 ton per ha) and barren
land (6/97 ton per ha), respectively. Moreover, organic carbon in the 0-15 cm depth of
soil in forested stands is more than the 15-30 cm ones; while a reverse trend is observed
in the arid land. Also, stepwise regression is shown that organic material and nitrogen
are the most important components affecting carbon sequestration. As a consequence, the
aforementioned stands are of a tremendous help towards an increase in the amount of
carbon sequestrated into soil (11.99, 7.89, and 2.72 ton per ha) against that of control land.
