Abstract
Carbon sequestration needs to be accompanied by socio-economic enhancements, especially, in developing countries like Pakistan. Agroforestry has been considered as an ancient practice throughout the country but the knowledge about its impacts on tree and soil carbon storage is minimal. Growth, biomass, carbon stocks and CO2 sequestration rate in three different age classes of Populus deltoides Bartr. Ex Marsh. planted in linear patterns along boundaries (bund planting) were estimated in three subdivisions (Tehsils) of district Chiniot (Bhawana, Chiniot and Lalian) of Punjab, Pakistan. For estimating tree biomass and carbon stocks, allometric equation was used and soil organic carbon (SOC) was assessed at two depths (0-15 and 15-30 cm). The diameter at breast height (DBH) and height of trees were higher at 4-6 years as compared to 2-4 years and the plant biomass was found the maximum (90.55 Mg ha-1) in Tehsil Lalian at 6 years. Total carbon stocks and CO2 sequestration rate varied from 0.89 Mg ha-1 and 1.63 Mg ha-1 yr-1 at 2 years to 43.54 Mg ha-1 and 26.58 Mg ha-1 yr-1 at 6 years, respectively, across all Tehsils. Total SOC stocks were maximum (43.73 Mg ha-1) at 6 years in Tehsil Lalian while minimum 27.92 Mg ha-1 in Tehsil Bhawana at 2 years. Overall, soil + tree carbon stocks increased with age and was maximum at 6 years: 61.54 Mg ha-1, 80.76 Mg ha-1, and 87.27 Mg ha-1 in Tehsil Bhawana, Chiniot, and Lalian, respectively. The above results encouraged the establishment of P. deltoides planting along farm crops as an important possibility for increased carbon storage and mitigation of atmospheric accumulation of CO2.
