Impact of citrus-based agroforestry systems on morphological characteristic of trees and carbon sequestration

Green plants can store carbon, which is an effective approach to lower atmospheric CO2. Forest tree species such as Tectona grandis, Eucalyptus tereticornis, and Ailanthus excels were assessed under a citrus-based agroforestry system for their above ground and belowground carbon sequestration potentials in the present study. The collar diameter (cm) and height (m) of mandarin under different citrus-based agroforestry systems were 3.00, 5.92, 4.72, and 4.70 and 1.47. 2.79, 2.23, and 2.55, respectively. The total standing below-and above-ground biomass of Tectona grandis was 10,63 and 2.76 t ha-1,of Eucalyptus teritocornis was 49.99 and 12.99 t ha-1 and of Ailanthus excelsa was 20.34 and 5.28 t ha-1, respectively. In contrast, the total standing biomass in the mentioned species of forest is 1339, 62.98, and 25.62 t ha-1. The standing biomass and AGB and BGB sequestered carbon stocks in Tectona grandis were 5.31 and 138 (ha), for Eucalyptus tereticornis 24.99 and 6.49 t ha-1 and for Ailanthus excelsa10.17 and 2.64 t ha-1, correspondingly, 6.69, 31.49, and 12.81 t C ha-1 carbon were sequestered in the above forest species.
