Abstract
In the present study the attempt has been made to quantify the “Biomass,
Carbon Stock and Carbon Sequestration in an Age series of Teak Plantation in
Tropical Environment” at Barnawapara Wildlife Sanctuary of Raipur Forest Division
in Raipur district (Chhattisgarh), during the year 2010-2013. The study was conducted
in age series of teak plantation viz. 19 years, 23 years and 33 years old plantations in
tropical environment. The variation in soil characteristics, species structure,
composition, diversity, biomass, forest floor biomass, fine root biomass, litterfall,
productivity and carbon sequestration and across the teak plantation sites were
quantified.
The soil of all the teak plantations in an age series is characterized by sandy
loam structure with considerably varying proportions of sand (53 – 66 %), silt (26 –
27 %) and clay (8 – 20 %). Bulk density ranged from 1.22 to 1.33 gm-3. Moisture
content ranged from 7.05 to 10.66 %. The soil pH was within the range 6.12 – 6.44.
Total N and C were between 0.06 - 0.14 % and 0.74 - 1.67 %, respectively. Available
P and K were between 8.45 – 15.26 kg ha-1 and 255.74 – 372.32 kg ha-1, respectively.
The C:N ratio was between 11.00 – 13.93. The microbial biomass carbon was
between 112.75 - 522.13 μ g g-1 of soil. The total soil carbon stock in 0-10 cm and 10-
20 cm soil layer was ranged between 13.90 - 21.37 t ha-1 and 9.85 – 15.28 t ha-1,
respectively.
In the present study, a total of 1100, 1440 and 1450 trees ha-1 were
encountered in 19, 23 and 33 years old teak plantations, respectively. The basal area
of tree species across the age series was 27.52, 42.65 and 45.84 m2 ha-1 in 19, 23 and
33 years old teak plantations, respectively. The total biomass across the age series of
teak plantation varied from 125.76 t ha-1 to 233.49 t ha-1. The above ground biomass
and below ground biomass was between 104.27 - 196.32 t ha-1 and 21.49 - 37.17 t ha-
1, respectively. The total forest floor biomass was between 778.67 and 985.84 g m-2
in rainy season, within 929.47 to 1250.97 g m-2 in winter season and within 993.19 to
1242.48 g m-2 in summer season.
