Abstract

Increase in cost of chemical fertilizers encourages the use of soil amendments such asbiochar and zeolites to improve soil fertility. In this study, biochar produced from emptyfruit bunch-palm oil mill effluent (EFB-POME) and clinoptilolite zeolite were used as soilamendments to improve soil fertility. The field experiment was carried out for twoplanting cycles to determine the effects of different rates of EFB POME biochar (0, 10, and20 t ha-1), clinoptilolite zeolite (0, 1.25, and 2.5 t ha-1), and urea (60 and 120 kg ha-1) onselected soil chemical properties of Tanjung Lipat (Typic Paleudults). Biochar producedfrom EFB-POME increase soil total N, P, K, Ca, and Mg. The higher soil total N, P, K, Ca, andMg could be related to the increase in soil pH, cation exchange capacity, and total organiccarbon in soil with EFB-POME biochar but not with clinoptilolite zeolite. Thus, EFB-POMEbiochar was more suitable to be used in a tropical soil (Typic Paleudults) compared toclinoptilolite zeolite for improving the selected soil pH, CEC, TOC and available P, K, Ca andMg.
