Peat is a type of wetland formed by piles of organic material in the form of tree remains, grass, moss and animal remains that decompose in the soil. Peatlands have several barriers to use as agricultural land, including pH <4, degradation due to land fires and chemical properties in peatlands that do not support plant growth and productivity. Provision of various bokashi fertilizers to increase nitrogen availability in peat soils. The research method used was a complete randomized design (CRD) with single factors. The factors tested were the formula of bokashi of ruminant manure (cow) and bokashi of poultry manure (chicken), both individually and in combination with 5 treatments and 1 control. The results of the study showed that after 4 weeks of incubation, the provision bokashi of cow manure and chicken manure formulas had a very significant effect on soil pH, C-organic, N-total and nitrogen availability (N-NH₄⁺ and N-NO₃^-). Adding 100% bokashi of cow manure can increase N-NH₄⁺, soil pH and decrease C-organic. Giving 100% bokashi of chicken manure can increase N-NO₃^-. Adding a combination of 70% bokashi cow manure + 30% bokashi of chicken manure can increase N-total and decrease C/N ratio.
