Abstract
Penelitian ini bertujuan untuk mengevaluasi status sifat tanah pada tanaman kelapa sawit (Elaeis guineensis Jacq) di Kelurahan Pulo Padang, Kecamatan Rantau Utara, tanpa penggunaan pupuk anorganik. Metode yang digunakan adalah survei lapangan dan analisis laboratorium terhadap sampel tanah yang diambil dari empat titik berbeda. Parameter yang diamati meliputi sifat kimia tanah (pH, C-organik, dan N total) serta sifat fisik tanah (tekstur). Hasil penelitian menunjukkan bahwa pH tanah rata-rata berada pada kategori netral (6,24), dengan kandungan C-organik rata-rata 2,29% yang tergolong tinggi, sedangkan N-total rata-rata 2,49% tergolong sangat tinggi. Tekstur tanah bervariasi antara lempung berpasir dan lempung berliat, yang berpengaruh pada retensi air dan ketersediaan nutrisi. Temuan ini menunjukkan bahwa meskipun tanpa penggunaan pupuk anorganik, tanah di Kelurahan Pulo Padang masih memiliki kesuburan yang cukup baik untuk mendukung pertumbuhan tanaman kelapa sawit. Penelitian ini diharapkan dapat menjadi dasar dalam pengelolaan tanah yang berkelanjutan di area perkebunan kelapa sawit. Kata Kunci : Kelapa Sawit, Sifat Tanah, pH, C-Organik, N-Total, Tanpa Pupuk Anorganik, Kesuburan Tanah, Tekstur Tanah ===================================================================================================== This study aims to evaluate the status ofsoil properties in oil palm (Elaeis guineensis Jacq) plants in Pulo Padang Village, Rantau Utara District, without the use of inorganic fertilizers. The methods used were field surveys and laboratory analysis of soil samples taken from four different points. The parameters observed included soil chemical properties (pH, C-organic, and N-total) and soil physical properties (texture). The results showed that the average soil pH was in the neutral category (6.24), with an average C-organic content of 2.29% which is classified as high, while the average N-total of 2.49% is classified as very high. Soil texture varies between sandy loam and clayey loam, which affects water retention and nutrient availability. These findings indicate that even without the use of inorganic fertilizers, the soil in Pulo Padang Village still has good enough fertility to support the growth of oil palm plants. This study is expected to be the basis for sustainable soil management in oil palm plantation areas. Keywords : Oil Palm, Soil Properties, pH, C-Organic, N-total, Without Inorganic Fertilizer, Soil Fertility, Soil Texture
