field studies that the application of fly ash @ 20 and 40 t per hectare increased the groundnut pod yield and rice grain yield significantly. Further, they observed that the effect of fly ash was much pronounced when flyash was integrated with fertilizers and organic manures. 11Selvakumari et al.(2000) found that the application of fly ash @ 40 t
carbon content of the fly ash, as indicated by the loss on ignition by mass, was as low as less than 2%. The particle size distribution tests revealed that 80% of the fly ash particles were smaller than 50 µm [7, 8, 11-18]. The reactivity of low-calcium fly ash in geopolymer matrix has been studied by Fernandez-Jimenez, et al [19].
amount of fly ash was added in the soil. At harvest of wheat crop in the C.C.R. (P.G.)
