Abstract

Abstract: Salah satu indikator kesuburuan tanah adalah sifat kimia tanah. Unsur hara yang berkualitas merupakan hasil dari proses pendekomposisian bahan organik, dan penambahan melalui pemupukan, sehingga berpengaruh terhadap unsur hara di dalam tanah seperti N, P, K, kation-kation basa (Ca, Na Mg), dan juga sifat kimia seperti KTK dan pH tanah. Metode yang digunakan dalam penelitian ini adalah metode deskriptif. Pengambilan sampel dilakukan di tiga lokasi yaitu Desa Suranadi Kecamatan Narmada (lahan kebun dan hutan), Desa Tempos Kecamatan Gerung (lahan tegalan dan semak belukar), dan Desa Kuripan Kecamatan Kuripan (lahan sawah) Kabupaten Lombok Barat. Penelitian ini dilakukan pada bulan Agustus. Hasil analisis menunjukkan penggunaan lahan hutan memiliki tingkat kesuburan paling tinggi yang ditunjukkan oleh kandungan N-total 0,47 %, P-tersedia 42,57 ppm, K-tertukar 1,48 cmol+ kg⁻1, KTK 25,07 cmol+ kg⁻1, pH 6,7, Ca 9,20 me/100g, Na 0,06 me/100g, Mg 2,05 me/100g yang memadai. Abstract: One indicator of soil fertility is the chemical nature of the soil. Quality nutrients are the result of the decomposition process of organic matter, and additions through fertilization, so that they affect the nutrients in the soil such as N, P, K, basic cations (Ca, Na Mg), as well as chemical properties such as CEC and soil pH. The method used in this research is descriptive method. Sampling was carried out in three locations, namely Suranadi Village, Narmada District (garden and forest land), Tempos Village, Gerung District (moor land and shrubs), and Kuripan Village, Kuripan District (rice field) West Lombok Regency. This research was conducted in August. The results of the analysis showed that forest land use had the highest fertility level, indicated by the content of Ntotal 0.47%, available P-42.57 ppm, K-switched 1.48 cmol+ kg⁻1, CEC 25.07 cmol+ kg⁻1 , pH 6.7, Ca 9.20 me/100g, Na 0.06 me/100g, Mg 2.05 me/100g were adequate.
