Analysis of grains grown on fly ash treated soils

One time application of fly ash was done at the rate of 200 t/hectare in the crop lands in Odisha, India. The increase in yield of maize grains was 28% and 34% over the control values whereas the increase in yield of rice grains was 40% and 13% at Malud and Dhenkanal, respectively. The results indicated that fly ash is an amendment for soil which can improve the physical and chemical properties of deficient soil and improves the soil fertility and crop yield.

► Fly ash was applied in the soil and some crops were harvested.
► Increase in yield of these grains was significant.
► Increase in maize yield was 28–34% and rice yield was 13–40%.
► Elemental composition was normal and well below the critical levels in the plants.
► Hence, fly ash treated grains are safe for consumption.
