Bentuk Usahatani Konservasi di Lahan Marjinal Untuk Meningkatkan Penerimaan Petani pada DTA Singkarak

Latar Belakang

Potensi Lahan MarjinalSangat Luas Potensi untuk lahan pertanianMasalah Lahan MarjinalSifat Fisika, Kimia dan Biologi Tanah buruk Latar Belakang

Tujuan Penelitian1). Mempelajari pengaruh restorasi ekologi tanah terhadap sifat tanah2). Mempelajari pengaruh restorasi ekologi tanah terhadap produksi tanaman, 3). Mempelajari pengaruh restorasi ekologi tanah terhadap penerimaan petani, 4). Mempelajari pengaruh usahatani konservasi terintegrasi terhadap penerimaan petani dan kehidupan satu keluarga yang layak diatas garis kemiskinan.

Alang-alang dibabat, dipotong kira-kira 20 cm dijadikan mulsa 10 ton ha-1+ sisa tanaman dijadikan mulsa dan tanah diolahdengan traktor.

Alang-alang dibabat kemudian daun dan rimpang alang-alang dikomposkan dan tanah diolah +kapur CaCO3 1 ton ha-1+pupuk kandang 10 ton ha-1 tahun-1 dan ditambah kompos alang-alang (7 ton ha-1) dan sisa tanaman dijadikan mulsa dan campuran pakan sapi, kemudian kotoran sapi dikembalikan pada petak R2.

Alang-alang disemprot dengan herbisida sistemik Round up kemudian alang-alang direbah-kan+ sisa panen tanaman dijadikan mulsa, tanah diolah minimum menurut barisan tanamanAnakT1
