<![CDATA[Peningkatan retensi nitrogen pada lahan tembakau merupakan strategi penting peningkatan mutu dan produksi tembakau. Pupuk slow release dari biochar sumber nitrogen dari pupuk kimia, urin sapi dan bakteri diyakini mampu meningkatkan retensi nitrogen dan efisien serapan hara. Oleh karena itu kegiatan ini bertujuan untuk mengimplementasikan penggunaan pupuk slow release pada budidaya tembakau. Metode pelaksanaan kegiatan meliputi: 1) penyuluhan penggunaan bahan pembenah tanah; 2) pendampingan produksi pupuk slow release; 3) pendampingan pembibitan tembakau standar SNI; 4) demplot penerapan GAP pada budidaya tembakau; dan 5) pemantauan aplikasi pupuk slow release dan pertumbuhan tanaman. Hasil kegiatan menunjukkan partisipasi aktif petani dari 2 kelompok tani yakni Mamminasa Deceng dan Alemarajae serta perwakilan dari GAPOKTAN Ujung Rilau, dimana berhasil diproduksi pupuk slow release sebanyak tiga formula, yakni 1) Biochar + SP36; 2) Biochar + SP36 + urin sapi; dan 3) Biochar + SP36 + urin sapi + Azotobacter. Keempat formulasi pupuk telah distandarisasi oleh lembaga sertifikasi karbon internasional Biochar Life, sehingga dapat direkomendasikan untuk diterapkan di lahan pertanian khususnya lahan tembakau.

ABSTRACT Increasing nitrogen retention in tobacco fields is an important strategy to improve tobacco quality and production. Slow-release fertilizer from biochar, a source of nitrogen from chemical fertilizers, cow urine and bacteria, is believed to be able to increase nitrogen retention and efficient nutrient absorption. Therefore, this activity aims to implement the use of slow-release fertilizer in tobacco cultivation. The implementation methods of the activity include: 1) counseling on the use of soil conditioners; 2) assistance in the production of slow-release fertilizers; 3) assistance in the production of SNI standard tobacco; 4) demonstration plots for the application of GAP in tobacco cultivation and; 5) monitoring the application of slow-release fertilizers and plant growth. The results of the activity showed the active participation of farmers from 2 farmer groups, namely Mamminsa Deceng and Alemarajae, and representatives from GAPOKTAN Ujung Rilau, where three formulas of slow-release fertilizers were successfully produced, namely 1) Biochar + SP36; 2) Biochar + SP36 + Cow urine; and 3) Biochar + SP36 + Cow urine + Azotobacter. The four fertilizer formulations have been standardized by the international carbon certification body Biochar Life so that they can be recommended for application on agricultural land, especially tobacco land.
