Abstract

Lumban Julu subdistrict is one of the producer Arabica coffee in Toba Samosir District. To know the soil fertility status is very important to increase production Arabica coffee. This research aims to map the soil fertility in Arabica coffee plantation in Lumban Julu Subdistrict, Toba Samosir district. Soil samples were taken from each Soil Map Unit (SMU) and analyzed at the Laboratory. Observed parameters were cation exchange capacity (CEC), bases saturation, C-organic, P-total and K-total. The research showed that all soil fertility status of SMU 1 until SMU 8 were low criterion.

Kecamatan Lumban Julu adalah salah satu penghasil kopi Arabika di Kabupaten Toba Samosir. Untuk mengetahui status kesuburan tanah sangat penting untuk meningkatkan produksi kopi arabika. Penelitian ini bertujuan untuk memetakan kesuburan tanah di perkebunan kopi Arabika di Kecamatan Lumban Julu, Kabupaten Toba Samosir. Sampel tanah diambil dari masing-masing Unit Peta Tanah (SMU) dan dianalisis di Laboratorium. Parameter yang diamati adalah kapasitas pertukaran kation (KTK), saturasi basis, C-organik, P-total dan K-total. Penelitian menunjukkan bahwa semua status kesuburan tanah SMU 1 hingga SMU 8 adalah kriteria rendah.
