Abstract

This research aims to determine the effect of biochar giving corn cobs and rice husks on Vertisol from Kupang Regency of East Nusa Tenggara. The study used a complete randomized design of two factors with three replays. The first factor is a type of biochar consisting of biochar corn cobs and rice husks. The second factor is the biochar dose (% soil weight) consisting of 4 levels namely: 1.5 %, 3 %, 4.5 % and 6%. Chemical Properties observed in this study include pH, C-organic, Total Nitrogen, P2O5, K2O, and Soil Cation Exchange Capacity (CEC). The results showed that the administration of biochar corn cobs at a dose of 3 % gave the best results to C organic, P205, and CEC, while the highest value of total N and K soil was found in the biochar treatment of corn cobs at a dose of 6 %.

Keywords: biochar, Corn Cobs, Rice Husks, Chemical Properties, and Vertisol
