Sifat Fisika Tanah Pada Berbagai Penggunaan Lahan Dan Kelerengan Di Desa Air Panas Kecamatan Parigi Barat Kabupaten Parigi Moutong

ABSTRACT

This study aims to determine the physical properties of soil in various land uses and slopes in Air PanasVillage, West Parigi District, Parigi Moutong Regency. This research was conducted in Air Panas Village, West Parigi District, Parigi Moutong Regency. Soil sample analysis was carried out at the Laboratory of Soil Science Unit, Faculty of Agriculture, Tadulako University. The research was conducted from September 2020 to May 2021. This study used 6 observation variables, namely soil texture, soil volume weight, soil porosity, hydraulic conductivity, field capacity moisture content, and C-organic. The results showed that the use of dry land and plantations with slopes of 1-3% and 25-40% soil texture dominated by sandy loam criteria, soil volume weight with moderate criteria, soil porosity with very bad, bad and poor criteria, conductivity. hydraulics with slow and rather slow criteria, field capacity reaching 15.39% -27.02%, C-organic with very low criteria, low to moderate.

Key Words : Land use, slopes, soil physical characteristics.

ABSTRAK

Penelitian ini bertujuan untuk mengetahui sifat fisika tanah pada berbagai pengunaan lahan dan kelerengan di Desa Air Panas, Kecamatan Parigi Barat, Kabupaten Parigi Moutong. Penelitian ini dilaksanakan di Desa Air Panas, Kecamatan Parigi Barat, Kabupaten Parigi Moutong. Analisis sampel tanah dilakukan di Laboraturium Unit Ilmu Tanah, Fakultas Pertanian, Universitas Tadulako. Penelitian dilakasanakan pada bulan September 2020 sampai Mei 2021. Penelitian ini menggunakan 6 variabel pengamatan yaitu tekstur tanah, bobot volume tanah, porositas tanah, konduktivitas hidrolik, kadar air kapasitas lapang, dan C-organik. Hasil penelitian menunjukkan bahwa penggunaan lahan kering dan perkebunan dengan kelerengan 1-3?n 25-40% memiliki tekstur tanah didominasi dengan kriteria lempung berpasir; bobot volume tanah dengan kriteria sedang; porositas tanah dengan kriteria sangat jelek, jelek dan kurang baik; konduktivitas hidrolik dengan kriteria lambat dan agak lambat; kapasitas lapang mencapai 15,39%-27,02%; C-organik dengan kriteria sangat rendah sampai sedang.

Kata Kunci : Penggunaan lahan, kelerengan, karakeristik fisik tanah.
