Online Published on 5 January, 2024. Abstract Background Peatlands are marginal lands that have low soil pH, easy to experience nutrient retention and leaching. If this land is used for oil palm cultivation, it will affect its growth and production. These obstacles can be overcome by using fertilizer technology (Biochike+). Biochar Tankos is an organic fertilizer made from agricultural waste, which when combined with biochar chicken manure can be a highly nutritious organic fertilizer, plus Urea which can increase the total N of the soil. This study aims to examine the application of biochike+ fertilizer technology in peatlands to the growth of oil palm seedlings and the availability of N, P and K nutrients in peat soils. Methods The research was conducted in polybags with 6 levels of Biochike+ (B1, B2, B3, B4, B5 and B6) and 5 replications so that there were 30 polybags. The parameters observed were the height and number of leaves every month for 3 months and the chemical properties of the soil after an incubation period of 1 month including pH, N, P and K of available soil. The design was completely randomized design (CRD). Result The data obtained were analyzed statistically by analysis of variance (ANOVA) with a 5% significant difference test. showed that the application of Biochike 1 fertilizer (25% biochar Tankos: 75% biochar chicken manure: 100% Urea) gave the highest value to height growth and the availability of N, P, K nutrients in the soil. From an economic analysis, sales of Biochike+ at a price of 1.6 USD per kilogram at the biochar producer level, have provided a profitable value. There are 2 things that benefit from applying Biochike+ fertilizer, namely increasing crop yields and reducing the need for chemical fertilizers.
