The coal ashs which are burned at low temperature for the purpose of inhibiting nitrogen oxide generation have small size pores and contain relatively large amounts (〜35wt%) of carbon because of mperfect burning. We ixammed how to utilize these waste coal ashs for the adsorbent of agncultual chemicals. First, we tested the method of hardening or graining these coal ashs with cement Mortar by the ashs did not harden because of high water/cement ratios The pellets which are grained by the pan type pelletizer have more holding capacities of water and agncultual chemicals than by other methods The smaller the quantities of the adding cement are, the higher these abilities are and but the weaker the hardness of the pellets is Secondaly, we examined the abilities of holding or adsorption of 13 kinds of agncultual chemicals on the pellets These chemicals can be well holded or adsorpted with a few exceptions for Captain. The larger the contents of carbon in coal ashs are, the greater these abilities are.
