Abstract：
 This invention relates to a new usage of desulfurized wastes of coal smoke and a method for improving alkali earth, in which, the method includes: sampling an earth-sample to test it and computing the volume of Na2CO3, NaHCO3, Mg(HCO3)2,+)Na and Mg, computing the mol volume of CaSO4 necessary for the reform then computing the necessary volume for getting the smoke desulfurized wastes based on their composition to spread the wastes on the earth¡¯s surface and irrigate it and applying the field management measure same to the ordinary earth.
