Utilization of waste oil palm empty fruit bunches as an ameliorant in the form of biochar enriched with chicken manure and urea fertilizer to increase the fertility of immature (seedling) oil palm planted on peat soil which has poor soil physical, chemical, and biological characteristics.
Methods: Biochar material, namely empty fruit bunches, was subjected to conventional pyrolysis for 3, 4 and 5 hours at a temperature of 4000C. Then the biochar is weighed to get the desired proportion of biochar then sieved through a 60 mesh sieve.nd analyzed for pH, ash content, organic-C, total-N, total-P, total-K, as well as biochar functional groups using Fourier Transform Infrared Spectroscopy (FTIR), and structural analysis using Scanning Electron Microscopy (SEM). The implementation of the research consisted of 2 activities, namely 1) Planting oil palm seedlings in polybags by giving treatment according to the dose and 2) Chemical characterization of biochar, peat soil properties and growth and NPK uptake of oil palm seedlings
