KARAKTERISTIK SIFAT KIMIA TANAH DAN STATUS KESUBURAN TANAH LAHAN PEKARANGAN DAN LAHAN USAHA TANI BEBERAPA KAMPUNG DI KABUPATEN KUTAI BARAT
Abstrak: The purpose of the
study was to determine the soil chemical characteristics of the soil and soil
fertility status at the home yard and farm lands in several villages of West
Kutai District.The experiment was conducted for 3 (three) months, from April
2013 to July 2013 in the villages of Muut and Dempar of Nyuatan Sub District, Purwodadi
Village of Linggang Bigung Sub District; Sumber Sari Village of Barong Tongkok
Sub District, and Melak Ilir Village of West Kutai District. This study used
survey system, followed by soil sampling compositely at a depth of 0-20cm. The composite soil samples were then analyzed
in the laboratory.The main data that were collected include soil pH, organic C,
total N, the C/N ratio, available P, cation-exchangeable base cations, CEC,
base saturation, and saturation Aluminum.
The data were analyzed using soil chemical status assessment criteria
and soil fertility assessment criteria of Bogor Soil Research Center. The
results showed that: (1) the character of the soil chemical properties at home
yard and farm land at several villages in West Kutai District, namely: soil pH
is very acidic to acidic, organic C content is low to high, N total is low to
moderate, C/N ratio is moderate to high, available P is very low to moderate,
CEC is relatively very low, base cations classified as very low to moderate, and
Al saturation is low to very high; and (2) the status of soil chemical
fertility in the home yard and farm land at several villages in West Kutai
District is classified as very low to low.
