[KINETIKA NITRAT DI DALAM TANAH PADA APLIKASI VERMIKOMPOS]. Nitrogen seringkali mengalami defisiensi didalam tanah dan berdampak terhadap produktivitas tanaman yang erat kaitannya dengan isu ekonomi saat ini. Nitrogen hadir didalam tanah melalui beberapa proses dan perubahan, seperti mineralisasi dan mobilisasi, nitrifikasi, denitrifikasi, volatilisasi, erosi dan limpasan, serta pencucian. Nitrat merupakan unsur nitrogen yang sulit tersedia bagi tanaman, karena sifatnya yang sangat mudah hilang oleh aktifitas organisme seperti immobilisasi, denitrifikasi, hingga proses pencucian/limpasan oleh air hujan. Selain itu, ketersediaan nitrat sangat tergantung oleh kemasaman didalam tanah sehingga unsur ini seringkali menjadi tidak tersedia bagi tanah masam, seperti Ultisol dan Inceptisol. Penelitian ini bertujuan untuk menentukan laju ketersediaan nitrat pada tanah Inseptisol dan Ultisol setelah pemberian beberapa taraf dosis pupuk vermikompos kotoran sapi. Penelitian ini menggunakan RAL (Rancangan Acak Lengkap) 2 faktor. Faktor pertama adalah dosis vermikompos kotoran sapi, yaitu 0, 15, dan 30 ton/ha dan faktor kedua adalah dua jenis tanah, yaitu Inceptisol dan Ultisol. Pengulangan dilakukan sebanyak 3 kali. Hasil penelitian menunjukkan bahwa proses nitrifikasi melalui ketersediaan NO3- pada tanah yang diinkubasi selama 7 minggu dan data yang dianalisis dengan first order kinetic model. Pada tanah Inceptisol, laju nitrifikasi (k) sejumlah 0,04 sampai 0,06 mg/kg perhari. Potensial nitrifikasi (N0) menunjukkan 1,36-1,41 mg/kg/hari. Pada tanah ultisol, N0 meningkat dari 1,21 sampai 1,44 mg/kg perhari dan k sebesar 0,04-0,06 per hari. Dosis vermikompos 30 ton/ha mampu meningkatkan nitrat di dalam tanah sebesar 1,44 mg/kg/hari untuk tanah Ultisol dan 1,41 mg/kg/hari untuk tanah Inceptisol. Vermikompos kotoran sapi dapat meningkatkan proses nitrifikasi pada tanaman masam, seperti Ultisol dan Inceptisol. Pupuk organik ini mampu meningkatkan ketersediaan nitrat melalui peningkatan aktifitas mikroorganisme.
