Abstract

The objective of research was to know study the effect of fly ash and manure to chemical properties of the coal mine soil. This research was conducted from February unti April 2014 at greenhouse of Department of Agriculture Faculty, Jambi University. The experiment was arranged in a factorial randomized completely block factorial design with two factor of treatments and three replications. First treatment was six dosages fly ash (0, 15, 30, 45, 60, 75 ton ha-1) and second was three dosages manure ( 0, 2,5, 5% based on the weight of the soil). Applications of fly ash 75 ton ha-1 and manure 5% resulted in a significant effect on availability of increasing Ca-dd from 0,04 to 2,09 cmol kg-1, Mg-dd from 0,06 to 1,15 cmol kg-1, decreasing Al-dd from 3,36 to 0,04 cmol kg-1) but did not significantly effect on pH.
