dc.description.abstractThe study reported here was conducted to estimate carbon stocks in Uchindile forest plantation, Kilombero district, Tanzania. The tested hypothesis was Pinus patula and Eucalyptus saligna plantations had similar carbon sequestration. Data was collected from two main plantation species i.e. Pinus patula and Eucalyptus saligna. Stratified random sampling design was adopted. Three sample plots measuring 20 m x 20 m were established in each stand. Diameter at breast height (DBH) and height were measured for stand data estimation, especially volume. Top soil samples 0-15 cm and 15-30 cm depths were sampled. Then, total biomass and soil carbon stored in the plantation was prepared using Microsoft Excel. The CO2FIX was used to estimate biomass and soil carbon in the two plantations. Lundgren equations were used to estimate biomass in the pine plantations. For each species, stand ages selected were 4, 6, 8, and 10 years. Field data results indicated that at year 4, 6, 8, and 10 Pinus patula plantations sequestered stand biomass C of 7.48, 21.34, 42.22 and 61.48 Mg Cha1. Eucalyptus saligna plantations sequestered stand biomass C of 43.5, 137.53 and 183.71 Mg Cha’1. Pinus patula plantation had mean soil C of 81.29, 80.03, 76.76 and 76.47 Mg Cha'1 at year 4, 6, 8, and 10, respectively. Eucalyptus saligna plantation had mean soil C of 73.65, 86.06 and 77.77 Mg Cha’1 at year 6, 8 and 10. The two plantations sequestered total C of 218.18, 342.04 and 399.43 Mg Cha’1 at year 6, 8 and 10, respectively. This translates to 800.72, 1255.29 and 1465.91 Mg COjha’1, at the respective ages. Mg COzha’1 = Mg Cha’1 multiplied by 3.67. The T test indicated a very significant (P<0.05) difference in carbon sequestration between the two plantation species. Eucalyptus plantations sequestered 1.15 to 1.89 times more carbon in comparison to the pine.
