OF FLY ASH IN AGRICULTURE
The study was
carried out from Oct' 90 to March'98. The
conclusion drawn from the studies are:
The presence of potentially toxic metals viz, Cd, Cr, Cu,
Fe, Ni, Mn, Pb, Zn and Hg have
been found in Permissible limits.
Levels of essential trace elements, nutritional parameter
such as starch, Protein, Vitamin 'C' and 'E' did not show any decrease in the crops produced in fly ash amended soil.
Consumption of fly ash amended crops did
not cause any hematological changes relative organ weight, body organ weight
ratio, blood glucose, liver glycogen etc.
Reproductive performance and growth of
next generation were also unaffected.
Enzyme profile confirmed that there is no
abnormality in vital organ function.
Thus it can be concluded that the
amendment of soil with fly ash is safe for agriculture purposes.
