Penelitian ini bertujuan untuk mengukur pengaruh perlakuan terhadap besarnya pelindian NH4 + dan NO3 - di tanah sulfat masam yang diberi pupuk kandang ayam + biochar dan tanaman padi. Penelitian ini dilaksanakan di rumah kaca dengan menggunakan Rancangan Acak Kelompok (RAK) faktor tunggal dengan kombinasi perlakuan, diaman ada tanah saja, tanah + varietas tanaman padi, tanah + pupuk kandang ayam + biochar, dan pupuk kandang ayam + biochar + varietas tanaman padi dan masing-masing perlakuan diulang empat kali. Hasil penelitian menunjukkan bahwa perlakuan pupuk kandang ayam + biochar tidak berpengaruh terhadap kemampuan menahan pelindian NH4 + dan NO3 - pada satu minggu sebelum tanam, namun pada empat minggu setelah tanam perlakuan pupuk kandang ayam + biochar berpengaruh hanya menurunkan pelindian NH4 + . Sedangkan varietas tanaman berpengaruh hanya terhadap pelindian NO3 - .

This study aims to measure the effect of treatment on the size of NH4 + and NO3 - leaching in acid sulphate soils by chicken manure + biochar and rice crops. This research was conducted in the greenhouse using a randomized block design (RAK) single factor with combination treatment, where there is soil only, soil + varieties of rice plants, soil + chicken manure + biochar and chicken manure + biochar + varieties of rice plants and the respective each treatment was replicated four times. The results showed that the treatment of chicken manure + biochar did not affect the ability to withstand the NH4 + and NO3 - leaching at one week before planting, but at four weeks after planting treatment of chicken manure + biochar affect only reduces leaching NH4 + . While the effect of plant varieties only to the NO3 - leaching. Keywords: Biochar , Chicken Manure, Inpara Rice , Sikin Rice , NH4 + , NO3 -
