Abstract

Coal fly ash and manure as ameliorant on the soil from the coal mine is ultilized to improve chemical properties of the soil in post-minning of coal and growth of the plant. It is also an attemp to control the environmental polution as a result from the coal burning process as an energy source. A research to investigate the dosses of fly ash and manure to chemical properties of the soil in post-minning of coal and also the growth and production of maize have been implemented to the coal mine land, which is belong to PT. Nan Riang at Muara Tembesi district in Batang Hari regency. The purpose of this research are to ascertain the dose and best possible combination from the dose of fly ash and organic materials to chemical properties of the coal mine soil and also the growth and production of maize in the coal mine soil. This research was conducted in the glasshouse by using 15 kg-size experimental pot with coal fly ash in 6 different levels; 0, 15, 30, 45, 60, 75 tonnes per hectare and 2 levels of cow manure as organic materials; 0% and 5% based on soil weight by using maize plant as an indicator. The results suggests that the level of 75 tonnes per hektare fly ash and cow manure as organic matters based on soil weight can improve pH H2O, Phosfor, Kalium, Ca, Mg, capasity exchengable cation, decrease Al-dd, and provides significant effect on the growth and production of maize, however the applied of 45 tonnes fly ash per hectare shows no significant difference in the growth production of maize nor the chemical properties of the againt the applied of 75 tonnes per hectare
