ANALISIS SIFAT KIMIA TANAH GAMBUT PADA TIGA TIPE PENGGUNAAN LAHAN DI DESA PANGKALAN PANDUK KECAMATAN KERUMUTAN KABUPATEN PELALAWAN
Abstract: This research was
conducted from January until May 2015 at Pangkalan Panduk Village Kerumutan
Subdistrict of Pelalawan Regency of Riau Province. The research aimed to
determine the differences value pH, C-organik, KTK, N-total, P-total, and
K-total at 0-50 cm, samples from forest peatlands, oil palm plantations at the
age of 7 years and industrial forest plantations Acacia crassicarpa at the age
of 6 years. The results showed an increase in pH by 0.03 % from peat forests
into oil palm plantations and increased pH also occurs in peat forests into
industrial forest by 0.96 %; an increase KTK of peat forests into oil palm
plantations amounted to 22.62 mg/100g and peat forests into plantations
amounting to 113.87 mg/100g; P-total increased from peat forests into oil palm
plantations amounted to 22.62 mg/100g and peat forests into plantations also
increased by 12.74 mg/100g; K-total increased from peat forests into oil palm
plantations of 2.73 mg/100g and peat forests into plantations by also increased
by 12.31 mg/100g. For C-organic chemical character changes occur perbedan where
a decline of peat forests into oil palm plantations amounted to 11.15 % and an
increase of C- organic peat forests into plantations by 0.05 % . Neither the N
- total increased from peat forests into oil palm plantations of 0.51 % and a
decline of peat forests into plantations by 0.31 %. We conclude changes in the
chemical character of peat for all parameters measure were influenced by the
changes in secondary forest peatland into oil palm plantations age of 7 years
and plantation forests Acacia crassicarpa age 6 years.
