A Study of Carbon Dioxide Emission in Different Types of Peatland Use in Kalimantan
ABSTRACT: Study of
carbon dioxide emissions
in different types
of peatlands use
in Central and
West Kalimantan has been conducted in January-June 2006 and January-April
2007. The study represents 4 types of land use in Central Kalimantan as
treatment: 5 years for chinesse cabbage, 10 years for chinesse cabbage, 5 years
for sweet corns, and 10 years for sweet corns. As for the treatments in West
Kalimantan, they include corn
field, Aloe vera
field, oil palm
plantation, and rubber
plantation. Carbon dioxide
was measured using infrared gas analysis (model EGM-4, PP systems, Hitchin, UK).
In Central Kalimantan, the highest CO2 is emitted from
sweet corn plants
(arable land for
10 years) by
0.79 g CO2/m2/hour,
chinesse cabbage plants (for 5 years) by 0.73 g CO2/m2/hour,
chinesse cabbage plants (for 10 years) by 0.67 g CO2/m2/hour and, the least, sweet
corn plants (for 5 years)
by 0.41 g
CO2/m2/hour. The highest
CO2 emission from
West Kalimantan is released
from rubber plants
at 1.22 g
CO2/m2/hour, followed by
palm oil plants
by 0.96 g CO2/m2/hour, Aloe vera plants by 0.68 g
CO2/m2/hour and corn plants by 0.35 g CO2/m2/hour. Groundwater table depth
are the most
important factors among
other factors that
influence CO2 emissions.
Groundwater table depth indicated
a positive correlation
with CO2 emissions
in all types
of peatlands use.
C-organic production of sweet corn plants at 11.66 t C/ha/year is higher
than that of chinesse cabbage plants at 1.64 t C/ha /year.
Corn plants produce
organic-C was 11.66
t C/ha/year, equivalent
to the amount
of loss of C through
CO2 emissions by 11.29 t C/ha/year.
