Abstract

Penilaian status kesuburan tanah penting dijadikan acuan dalam optimalisasi pengelolaan, peningkatan efisiensi dan produktivitas lahan pertanian. Penelitian ini bertujuan untuk mengetahui status kesuburan kimia tanah pada perkebunan karet rakyat melalui survei dengan pendekatan konsep posisi polypedon tanah dan kelas lereng lahan di Provinsi Jambi. Sampel tanah komposit diambil dari polypedon tanah atas, tengah, dan bawah pada tingkat persen lereng lahan 15-24%, 8-15%, 3-8%, dan 0-3%. Paramater kesuburan kimia tanah yang dianalisis adalah Kapasitas Tukar Kation (KTK), Kejenuhan Basa (KB), P2O5, K2O, C-Organik, N-Total dan pH tanah. Penentuan status kesuburan berdasarkan kriteria yang dikeluarkan Pusat Penelitian Tanah Bogor tahun 1983. Hasil penelitian menunjukkan bahwa status kesuburan kimia tanah tergolong rendah pada semua tingkat lereng lahan dan pada semua polypedon. Optimalisasi produktivitas budi daya tanaman karet di lokasi penelitian direkomendasikan agar melakukan pengapuran untuk peningkatan pH tanah, pemberian bahan organik dan pemupukan, terutama pupuk dengan unsur hara nitrogen, dan kalium.

Abstract

Tunas Makmur Farmers Group I of Ibru Village, Mestong District, Muaro Jambi Regency, Jambi Province has not yet made optimal use of a large amount of agricultural, plantation and industrial waste, due to farmers' lack of knowledge about biochar and its use to improve soil productivity. For this reason, the implementing team offers an easy, cheap and sustainable solution to manage and utilize abundant sources that can be used as a source of biochar. The objectives of implementing this community service activity can be achieved through: 1) counseling and training about the benefits of biochar to improve the physical and chemical properties of soil, 2) demonstration of making biochar from agricultural, plantation and industrial waste using drum pyrolysis, 3) assistance in calculating the dose given and application in the field through demonstrations on partner land on how to use biochars properly. Partners in this activity earn their main income from being food crop and plantation farmers. Agricultural, plantation and industrial waste is usually piled up on land and wasted because farmers do not yet have knowledge about the benefits of this waste. After conducting socialization and education through counseling and demonstrations about making biochar from agricultural and industrial waste, farmers have the motivation to use this waste as a source of soil carbon and as a soil conditioner.
