EFFECT OF FLYASH ON SOME PROPERTIES AND NUTRIENT CATIONS STATUS OF THE SOILSamiullah Khan and Rakesh Kumar Bhardwar
The effect of flyash (FA) on certain soil parameters such as pH, Electrical Conductivity (EC) and nutrient metal cations availability was measured in alkaline sandy loam soil of Aligarh district, U.P. (India).The applications of varying quantitites 0-35 gm. FA Kg 1 soil amendments in pot experiments have indicated the decrease in soil pH, increase in a nutrient metal cations status such as Ca2-, Mg2, Fe2-, Mn't, Zn2+ Cu2+, and Co2+ at lower doses upto 15 gm. FA kg' soil and thereafter they tend to decline while in the case of EC is found continue to rise throughout the entire range of study.The results have been discussed on the basis of chemical and microbial changes occurring in soil amended with FA.
