Abstract
One way to improve the soil chemical properties is adding ameliorant, for instance humic substance, to the soil. There were many kinds of organic matter as source of humic matter. This research was aimed to study the capabilityofhumicsubstancederived from non-productivecoal (subbituminous) powder which was extracted with solvent from fertilizer, salt and base (Urea, KCl, NaCl, and NaOH) and then it was used to improve the soil chemical properties of Oxisols. The improvement of chemical properties of Oxisol can be achieved by adding humic substance from subbituminous. Urea can be used to substitue the role of NaOH in solving humic materials and improving soil chemical properties of Oxisols. Humic materials which are extracted by Urea on recommendation 125 % and subbituminous in concentration 0.5 % to improve soilchemistrypropertiesofOxisols.
