abstract:
Electrostatic precipitator (ESP) fly ash obtained from a thermal power plant was mixed with a slightly alkaline soil on w/w basis for use as a potting mixture for poplar nursery and investigated for its influence on microbial activity and physical properties. Application of fly ash as an amendment @ 10% was found to be optimum for bacterial population, soil dehydrogenase activity and microbial biomass. Water holding capacity of fly ash amended soil increased and bulk density decreased as result of fly ash addition as compared to unamended soil. The suitability of fly ash to be used as a soil ameliorant in nursery plantations attains significance from the point of view of eco-friendly disposal of fly ash.
