Scientists applied desulfurization ash from some power plants to 40 mu of saline-alkali land in Inner Mongolia. As a result, corn and grass grew in this land. The scientists concluded that the desulfurized ash from coal-fired power plants can be used to transform saline-alkali land.
The saline-alkali land next to the 40-mu experimental field where no desulfurization ash was applied was covered with gray, and even weeds were rare, if true, best supports the scientist's conclusion.
