Abstract

Penanaman kembali perkebunan kelapa sawit merupakan salah satu cara alternatif untuk menjaga kelangsungan perkebunan kelapa sawit di masa yang akan datang namun penggunaan lahan untuk penanaman kelapa sawit yang ditanam kembali dengan bibit baru memiliki kelemahan, seperti tingkat produktivitas lahan dan kemungkinan perubahan struktur tanah akibat penanaman kelapa sawit di masa lalu. Produktivitas lahan dipengaruhi oleh status hara dan kesuburan tanah. Sebelum dilakukan penanaman pada lahan yang akan ditanami kembali perlu diketahui kandungan unsur hara yaitu Nitrogen, Fosfor, Kalium, C Organik, sehingga dapat diketahui status kesuburan tanah pada lahan tersebut. Penelitian dilakukan dengan metode survey, penelitian dilaksanakan di lahan tanaman kelapa sawit masyarakat Kelurahan Bakaran Batu Kecamatan Rantau Selatan Kabupaten Labuhanbatu dengan ketinggan 28 meter diatas permukaan laut, engambilan sampel dilakukan pada dua kedalaman yaitu kedalaman 0-30 cm dan kedalaman 30-60 cm. Pengambilan sampel juga dilakukan pada dua perbandingan lahan yaitu lahan milik masyarakat dan masing-masing dua kedalaman yang sama yaitu 5 sampel. Sampel tanah dari setiap lokasi dan kemudian dianalisis. Analisis tanah dilakukan di Laboratorium Socfindo Seed Production and Laboratories (SSPL) Kebun Bangun Bandar PT. Socfin Indonesia Sumatera Utara dan ditentukan statusnya berdasarkan Badan Penelitian dan Pengembangan Pertanian Kementan (2012). Hasil kajian menunjukkan status hara dan tingkat kesuburan tanah di lokasi tersebut rendah sehingga telah dilakukan upaya untuk memperbaiki status hara dan kesuburan tanah pada lahan yang akan dibangun. digunakan secara optimal untuk penanaman kelapa sawit. Kata kunci : Produktivitas Lahan, Kelapa Sawit, Penanaman Kembali, Unsur Hara ==================================================================================================== Replanting of oil palm plantations is an alternative way to maintain the sustainability of oil palm plantations in the future but the use of land for replanting oil palm with new seeds has drawbacks, such as the level of land productivity and the possibility of changes in soil structure as a result of planting oil palm in the past. Land productivity is influenced by nutrient status and soil fertility. Before planting on land to be replanted, it is necessary to know the nutrient content, namely Nitrogen, Phosphorus, Potassium, Organic C, so that the soil fertility status of the land can be determined. The research was conducted using a survey method, the research was carried out in the oil palm plantations of the people of Bakaran Batu Village, South Rantau District, Labuhanbatu Regency with an altitude of 28 meters above sea level, sampling was carried out at two depths, namely 0-30 cm depth and 30-60 cm depth. Sampling was also carried out on two comparisons of land, namely land owned by the community and each at the same two depths, namely 5 samples. Soil samples from each location and then analyzed. Soil analysis was carried out at the Socfindo Seed Production and Laboratories (SSPL) Kebun Bangun Bandar Laboratory of PT. Socfin Indonesia North Sumatra and its status is determined based on the Agricultural Research and Development Agency of the Ministry of Agriculture (2012). The results of the study showed that the nutrient status and soil fertility level at that location were low, so efforts have been made to improve the nutrient status and soil fertility on the land to be developed optimally used for planting oil palm.
