Abstract

Fly ash as a coal combustion residue of thermal power plants has been regarded as a problematic solid waste all over the world. Due to the environmental problems created by large-scale fly ash generation, efforts are being made to recycle these materials. Generally, fly ash is a ferro-alumino-silicate mineral containing considerable quantities of Ca, K, and Na. They may, however, contain considerable quantities of minerals (aluminosilicate minerals like Mullite), which dissolve under strongly acidic conditions to provide liming function. Because of their chemical characteristics, fly ash have the potential to ameliorate soil chemical properties, such as the point of zero charge (PZC). Mixing fly ash with organic manure may enhanced the quality of the amelioran to improve the soils chemical properties. In the present study, the possibility to improving the status PZC in fly ash (FA) and chicken manure (CM) mixtures was investigated. Fly ash was mixed with organic matter in the form of cow chicken manure at 0:4, 1:3, 2:2, 3:1 and 4:0 ratios and incubated for 60 days. The FA+CM mixture with incubation time tended to decrease of the PZC status compared with the FA or CM alone. Among the different compositions of FA+CM mixtures, the 2:2 mixture at 45 days incubation time appeared to exhibit the lowest of the PZC compared with the other treatments. This composition could be use as an amelioran to improve the soils chemical properties in terms of soil fertility and lowering PZC, and it is necessary for further research.
