Abstract： |
The method of utilizing fuel coal desulfurizing product in improving alkali soil includes first sampling soil; testing and calculating Na2CO3, NaHCO3, Mg(HCO3)2, Na and Mg amount to be increased or decreased and molar CaSO4 amount needed for improvement based on the formulae; calculating the needed desulfurizing product amount according to the desulfurizing product components; and applying the desulfurizing product to the surface of soil and irrigation. Compared with available technology, the present invention has the advantages of fast improving speed and high improving effect. |
