Abstract

Pertumbuhan dan produktivitas tanaman sering kali terhambat karena ketersediaan unsur hara tersebut di dalam tanah tidak mencukupi kebutuhan tanaman. Tujuan dari penelitian ini yaitu mengetahui status kandungan hara dan mencapai rekomendasi pemupukan pada tanaman durian di Agrowisata Kebon Kito Lubuklinggau. Penelitian ini menggunakan metode survei tingkat detail dengan peta skala 1:5.000 pada area studi seluas 23 hektar. Penentuan titik sampel tanah dilakukan dengan purposive sampling, yang disesuaikan dengan kondisi dan bentuk lahan di lapangan. Sifat kimia yang diamati adalah; pH, C-organik, N-total, P-tersedia, dan K-dd. Hasil analisis pH tanah memiliki kriteria masam yang berkisar antara 3,75 hingga 4,30. C-organik memiliki kriteria rendah hingga tinggi yaitu berkisar antara 1,08 % - 3,35%. N-total memiliki kriteria sangat rendah hingga sedang berkisar antara 0,01% - 0,22%. P-tersedia memiliki kriteria rendah yang berkisar antara 13,19 ppm - 15,51 ppm. K-dd memiliki kriteria rendah berkisar antara 0,12 hingga 0,38 cmol kg⁻¹. Berdasarkan hasil analisis didapatkan rekomendasi pemupukan N, P dan K pada lokasi penelitian di antaranya pupuk Urea dengan dosis yaitu berkisar antara 102,78 – 220,65 kg ha⁻¹, pupuk SP-36 berkisar antara 80,05 – 109,94 kg ha⁻¹, dan pupuk KCl yaitu berkisar antara 90,47 – 131,2 kg ha⁻¹.
