Abstract

Utilization of coal fly ash as ameliorant on the soil from the former coal mine itself, beside to improve the physical and chemical properties of the former coal mine soil also to improve the growth of the plant and also an attemp to control the environmental polution as a result from the coal burning process as an energy source. Researches into the provision of fly ash and organic matter to the physical and chemical properties of the soil of former coal mine and also the growth and production of maize have been implemented to the former coal mine land which is belong to PT. Nan Riang at Muara Tembesi district in Batang Hari regency. The purpose of these researches are to ascertain the dose and best possible combination from the provision of fly ash and organic materials against the physical and chemical properties of the former coal mine soil and also the growth and production of maize in the former coal mine soil. The researches were conducted inside glasshouse by using 15 kg-size experimental pot with provision of coal fly ash in 6 different doses; 0, 15, 30, 45, 60, 75 tonnes per hectare and 2 doses of cow manure as organic materials; 0% and 5% based on soil weight by using maize plant as an indicator. Result suggests that the provision of 75 tonnes per hentare fly ash and cow manure as organic matters based on soil weight can improve pH H2O, pH KCl, Ca, Mg, bases amount and saturation, Al-dd, H-ss and provides significant effect on the growth and production of maize, hewever the provision of 60 tonnes fly ash per hectare shows not significantly different in the growth production of maize nor the chemical properties of the againt the provision of 75 tonnes per hectare
