EFEK TINGGI MUKA AIR TANAH DAN PEMUPUKAN TERHADAP EMISI CO2 PADA TANAH GAMBUT DENGAN SERASAH DAUN AKASIA (Acacia crassicarpa)
Abstract: Indonesia has the
largest peatland among the tropical countries which are spread in Sumatra
mainly in province of Riau, Kalimantan and Papua. This study aims to know the
effect of water level and fertilization N, P, K on CO2 emissions in peatland
with litter of akasia (Acacia crassicarpa). This research was conducted in the
Screen House, Plant Laboratory Faculty of Agriculture, University of Riau, from
July to December 2013. This research was conducted experimentally using
completely randomized design (CRD) of non-factorial with 6 treatments and 3
replications. The data obtained were analyzed descriptively and then the data
is presented in tabular form. Parameters observed were CO2 emissions. The
results showed that the increase of water level depth from 30 cm to 90 cm
without fertilizer and with fertilizer N, P, K increase CO2 emissions were
observed in October. However, in November and December observation, CO2
emissions were obtained in each treatment is inconsistent comparing in Oktober
observation. Treatment of water level
with fertilizer N, P, K result in CO2 emissions lower than treatment without
fertilizer.
