Abstract

Tanaman karet (Hevea brasiliensis) akan mengalami penurunan produksi seiring bertambahnya usia tanaman dan telah berkurangnya unsur hara dalam tanah. Penelitian ini bertujuan untuk mengetahui sifat kimia tanah pada perkebunan tanaman karet yang di konversi menjadi tanaman kelapa sawit. Penelitian ini telah dilaksanakan pada bulan Oktober 2023 hingga Januari 2024 di perkebunan kelapa sawit milik PTPN III Kebun Aek Nabara Utara Kabupaten Labuhanbatu dan dianalisis di Laboratorium Tanah Fakultas Pertanian Universitas Sumatera Utara. Metode yang digunakan adalah metode observasi, pengambilan sampel dilapangan dan dianalisis di laboratorium untuk mendapatkan data kuantitatif. Parameter pengamatan meliputi; pH tanah, C organik, Nitrogen total, P tersedia, Kapasitas tukar kation dan Kejenuhan Basa. Hasil Peneltian menunjukkan Tingkat kesuburan tanah pada lokasi penelitian termasuk ke dalam kategori rendah. Faktor pembatas utama yang menjadi penyebab rendahnya kesuburan tanah adalah kandungan bahan organik tanah yang rendah dan untuk meningkatkan status kesuburan tanah di lokasi penelitian guna penanaman selanjutnya, maka diperlukan upaya berupa pengapuran dan pemupukan serta penambahan bahan organik agar ketersediaan unsur-unsur hara bagi tanaman lebih tercukupi. Kata Kunci : Areal Repanting, Tanaman Karet, Konversi, Kesuburan Tanah, Data Kuantitatif =================================================================================================== Rubber plants (Hevea brasiliensis) will experience a decrease in production as plants age and the nutrient content in the soil decreases. This study aims to find out the chemical properties of soil on plantations of rubber crops that are converted into palm and coconut crops. The research was conducted from October 2023 to January 2024 at the palm coconut plantation of PTPN III Aek Nabara North Garden in Labuhanbatu district and analyzed in the Land Laboratory of the Faculty of Agriculture of the University of Northern Sumatra. The methods used are observation methods, field sampling, and analysis in the laboratory to obtain quantitative data. Observation parameters include soil pH, C-organic, Total Nitrogen, Available P, Cation Interchange Capacity, and Base Fulness. The results of the survey showed that the level of soil fertility at the site of the research was included in the low category. The main limiting factor that causes the low fertility of the soil is the low content of organic material in the soil. In order to improve the fertility status of the ground at the research site for further planting, it is necessary to make efforts such as irrigation and fertilization, as well as the addition of organic materials, to make the availability of nutrients for plants more affordable.
