Abstract

Background: Coal mined reclaimed soil is prone to losing organic carbon content, increased soil acidity, soil structural damage and compact. This degradation of soil properties can be reduced and improved by applying coal and coal impurities as potential ameliorants. This research was aimed at knowing the potential of coal and coal impurity (partings) to improve the physicochemical properties of coal mine reclaimed soil. Methods: The research was conducted using the randomized block design (RBD) with 3 types of treatment and was in a pot experiment. The tried treatments, among others, are 1) Control (K0), 2) Coal ameliorant (C) and 3) Coal impurity (partings) ameliorant (B). Coal and coal impurity (partings) were both tested with 5 doses, which respectively consisted of 5, 10, 15, 20 and 25 tons ha. Result: The results showed that the application of bituminous coal ameliorant and coal impurity significantly affected on physicochemical soil reclamation properties of coal mines. Both types of ameliorants had an effect on increasing pH and decreasing Al-dd contents but were only significantly different from the control (K0). Amelioration significantly affected the increase in the C-organic, Humic acid and N total content with doses of the applications bituminous coal C5, while coal impurity doses of C4. Key words: Ameliorant, Bituminous coal, Coal impurity (Partings), Coal mine reclamation, Soil properties.
