SIFAT KIMIA TANAH PADA BERBAGAI TIPE PENGGUNAAN LAHAN DI SEKITAR TAMAN NASIONAL LORE LINDU (STUDI KASUS DESA TORO KECAMATAN KULAWI KABUPATEN SIGI SULAWESI TENGAH)
ABSTRACT: Over the function of
land can affect soil condition that involve either chemical, physical or biological characteristic of it. Soil
chemical component that affected by : soil pH, C-organic, N, P, K and Cation
Exchange Capacity. Toro village in Sigi Subdistrict is a village nearby Lore
Lindu National Park that has different types of
land use. The research aimed to find out the soil chemical
characteristic in various types of land uses around Toro village, Kulawi subdistrict,
Sigi District, Central Sulawesi. The research was conducted on May up to the
month of July 2015, on three types of land uses were primer forest (Wana
Ngkiki), secondary forest (Pangale) and agroforestry land (Oma) around Lore Lindu National Park, Toro
village, Kulawi subdistrict, Sigi district, Central Sulawesi. The research
started by doing field survey, deciding
sample swath spot, taking soil sample, analyzing soil sample in laboratorium.
Deciding spot of taking soil sample was done purposively (purposive sampling)
which done in the depth of ≤ 30 cm. The
result of the research showed that the soil chemical characteristic of various
types of land uses was varies. Soil in primer forest (Wana Ngkiki) had chemical
chracteristic as follows: pH (H2O) that tended to be acid 5.05, C-organic 3,56
%, N-total 0,63 %, T- available (Bray I) 1,49 ppm, K-total 0,96 mg/100g and CEC
28,83 cmol (+) kg-1. Soil chemical characteristic of secondary forest (Pangale)
was pH (H2O) 4.78, C-organic 1.54 %, N-total 0.49 %, P-vailable (Bray I) 4.97
ppm, K-total 4.57 mg/100g dan CEC 8,46 cmol (+) kg-1. The soil chemical
characteristic of agroforestry land
(Oma) was pH (H2O) 5.05, C-organic 1.39 %, N-total 0.13 %, P-available (Bray I)
5.35 ppm, K-total 3.73 mg/100g and CEC 8.93 cmol (+) kg-1.
